GENERAL DESCRIPTION
The HY29DS162/HY29DS163 (HY29DS16x) is a
16 Mbit, 1.8 volt-only CMOS Flash memory organized as 2,097,152 (2M) bytes or 1,048,576 (1M)
words. The device is available in 48-pin TSOP
and 48-ball FBGA packages. Word-wide data
(x16) appears on DQ[15:0] and byte-wide (x8) data
appears on DQ[7:0].
The HY29DS16x Flash memory array is organized
into 39 sectors in two banks. Bank 1 contains
eight 8 Kbyte boot/parameter sectors and 3 or 7
larger sectors of 64 Kbytes each, depending on
the version of the device. Bank 2 contains the
rest of the memory array, organized as 28 or 24
sectors of 64 Kbytes:

28 x 64KB/32KW
HY29DS163
8 x 8KB/4KW
7 x 64KB/32KW
24 x 64KB/32KW
The device features simultaneous read/write operation which allows the host system to invoke a
program or erase operation in one bank and immediately and simultaneously read data from the
other bank, except if that bank has any sectors
marked for erasure, with zero latency. This releases the system from waiting for the completion
of program or erase operations, thus improving
overall system performance.
The HY29DS16x can be programmed and erased
in-system with a single 2.0 volt ± 10% VCC supply.
Internally generated and regulated voltages are
provided for program and erase operations, so that
the device does not require a higher voltage VPP
power supply to perform those functions. The device can also be programmed in standard EPROM
programmers. Access times as low as 120 ns are
offered for timing compatibility with the zero wait
state requirements of high speed microprocessors. To eliminate bus contention, the HY29DS16x
has separate chip enable (CE#), write enable
(WE#) and output enable (OE#) controls.
The device is compatible with the JEDEC singlepower-supply Flash command set standard. Commands are written to the command register using
standard microprocessor write timings, from where
they are routed to an internal state-machine that
controls the erase and programming circuits.
2
Device programming is performed a byte/word at
a time by executing the four-cycle Program Command write sequence. This initiates an internal
algorithm that automatically times the program
pulse widths and verifies proper cell margin. Faster
programming times can be achieved by placing
the HY29DS16x in the Unlock Bypass mode, which
requires only two write cycles to program data instead of four.
The HY29DS16x’s sector erase architecture allows any number of array sectors, in one or both
banks, to be erased and reprogrammed without
affecting the data contents of other sectors. Device erasure is initiated by executing the Erase
Command sequence. This initiates an internal algorithm that automatically preprograms the sector before executing the erase operation. As during programming cycles, the device automatically
times the erase pulse widths and verifies proper
cell margin. Hardware Sector Group Protection
optionally disables both program and erase operations in any combination of the sector groups,
while Temporary Sector Group Unprotect, which
requires a high voltage on one pin, allows in-system erasure and code changes in previously protected sector groups. Erase Suspend enables the
user to put erase on hold in a bank for any period
of time to read data from or program data to any
sector in that bank that is not selected for erasure. True background erase can thus be
achieved. Because the HY29DS16x features simultaneous read/write capability, there is no need
to suspend to read from a sector located within a
bank that does not contain sectors marked for erasure. The device is fully erased when shipped
from the factory.
Addresses and data needed for the programming
and erase operations are internally latched during
write cycles. The host system can detect completion of a program or erase operation by observing
the RY/BY# pin or by reading the DQ[7] (Data#
Polling) and DQ[6] (Toggle) status bits. Hardware
data protection measures include a low VCC detector that automatically inhibits write operations
during power transitions.
After a program or erase cycle has been completed, or after assertion of the RESET# pin (which
terminates any operation in progress), the device
is ready to read data or to accept another comr1.3/Apr 01
HY29DS162/HY29DS163
mand. Reading data out of the device is similar to
reading from other Flash or EPROM devices.
The Secured Sector is an extra 64 KByte sector
capable of being permanently locked at the factory or by customers. The Secured Indicator Bit
(accessed via the Electronic ID mode) is permanently set to a 1 if the part is factory locked, and
permanently set to a 0 if customer lockable. This
way, customer lockable parts can never be used
to replace a factory locked part. Factory locked
parts provide several options. The Secured Sector may store a secure, random 16-byte ESN (Electronic Serial Number), customer code programmed
at the factory, or both. Customer Lockable parts
may utilize the Secured Sector as bonus space,
reading and writing like any other Flash sector, or
may permanently lock their own code there.
The WP#/ACC pin provides access to two functions. The Write Protect function provides a hardware method of protecting certain boot sectors
without using a high voltage. The Accelerate function speeds up programming operations, and is
intended primarily to allow faster manufacturing
throughput.
Two power-saving features are embodied in the
HY29DS16x. When addresses have been stable
for a specified amount of time, the device enters
the automatic sleep mode. The host can also place
the device into the standby mode. Power consumption is greatly reduced in both these modes.
Common Flash Memory Interface (CFI)
To make Flash memories interchangeable and to
encourage adoption of new Flash technologies,
major Flash memory suppliers developed a flexible method of identifying Flash memory sizes and
configurations in which all necessary Flash device
parameters are stored directly on the device.
Parameters stored include memory size, byte/word
configuration, sector configuration, necessary voltages and timing information. This allows one set
of software drivers to identify and use a variety of
different, current and future Flash products. The
standard which details the software interface necessary to access the device to identify it and to
determine its characteristics is the Common Flash
Memory Interface (CFI) Specification. The
HY29DS16x is fully compliant with this specification.

Type
Description
Inputs
Address, active High. In word mode, these 20 inputs select one of 1,048,576
(1M) words within the array for read or write operations. In byte mode, these
inputs are combined with the DQ[15]/A[-1] input (LSB) to select one of 2,097,152
(2M) bytes within the array for read or write operations.
Data Bus, active High. In word mode, these pins provide a 16-bit data path
Inputs/Outputs for read and write operations. In byte mode, DQ[7:0] provide an 8-bit data path
Tri-state
and DQ[15]/A[-1] is used as the LSB of the 21-bit byte address input. DQ[14:8]
are unused and remain tri-stated in byte mode.
BY TE#
Input
Byte Mode, active Low. Controls the Byte/Word configuration of the device.
Low selects Byte mode, High selects Word mode.
CE#
Input
Chip Enable, active Low. This input must be asserted to read data from or
write data to the HY 29DS16x. When High, the data bus is tri-stated and the
device is placed in the Standby mode.
Input
Output Enable, active Low. This input must be asserted for read operations
and negated for write operations. BY TE# determines whether a byte or a word
is read during the read operation. When High, data outputs from the device are
disabled and the data bus pins are placed in the high impedance state.
Input
Write Enable, active Low. Controls writing of command sequences in order to
program data or erase sectors of the memory array. A write operation takes
place w hen WE# is asser t ed w hile CE# is Low and O E# is High. BY TE#
determines whether a byte or a word is written during the write operation.
RESET#
Input
Hardware Reset, active Low. Provides a hardware method of resetting the
HY 29DS16x to the read array state. When the device is reset, it immediately
terminates any operation in progress. The data bus is tri-stated and all read/write
commands are ignored while the input is asserted. While RESET# is asserted,
the device will be in the Standby mode.

CONVENTIONS
Unless otherwise noted, a positive logic (active
High) convention is assumed throughout this document, whereby the presence at a pin of a higher,
more positive voltage (VIH) causes assertion of the
signal. A ‘#’ symbol following the signal name,
e.g., RESET#, indicates that the signal is asserted
in the Low state (VIL). See DC specifications for
VIH and VIL values.
Whenever a signal is separated into numbered
bits, e.g., DQ[7], DQ[6], ..., DQ[0], the family of
bits may also be shown collectively, e.g., as
DQ[7:0].
The designation 0xNNNN (N = 0, 1, 2, . . . , 9, A, .
. . , E, F) indicates a number expressed in hexadecimal notation. The designation 0bXXXX indicates a
number expressed in binary notation (X = 0, 1).
MEMORY ARRAY ORGANIZATION
The 16 Mbit Flash memory array is organized into
39 blocks called sectors (S0, S1, . . . , S38). A
sector or several contiguous sectors are defined
as a sector group. A sector is the smallest unit
that can be erased and a sector group is the smallest unit that can be protected to prevent accidental or unauthorized erasure.
Sectors are also
combined into two ‘super’ groups designated as
banks.
In the HY29DS16x, eight of the sectors, which
comprise the boot block, are sized at eight Kbytes
(four Kwords), while the remaining 31 sectors are
sized at 64 Kbytes (32 Kwords). The boot block
can be located at the bottom of the address range
(HY29DS16xB) or at the top of the address range
(HY29DS16xT).
Tables 1 and 2 define the sector addresses and
corresponding array address ranges for the top
and bottom boot block versions of the HY29DS16x.
Table 3 specifies the bank organizations and corresponding bank addresses. See Tables 7 and 8
for sector group definitions.
Secured Sector Flash Memory Region
The Secured Sector (Sec2) feature provides a 64
Kbyte (32 Kword) Flash memory region that enables permanent part identification through an
Electronic Serial Number (ESN). An associated
‘Sec2 Indicator’ bit, which is permanently set at
the factory and cannot be changed, indicates
whether or not the Sec2 is locked when shipped
from the factory.
The device is offered with the Sec2 either factory
locked or customer lockable. The factory-locked
version is always protected when shipped from
the factory, and has the Sec2 Indicator bit permanently set to a ‘1’. The customer-lockable version
is shipped with the Sec2 unprotected, allowing
6
customers to utilize the sector in any manner they
choose, and has the Sec2 Indicator bit permanently
set to a ‘0’. Thus, the Sec2 Indicator bit prevents
customer-lockable devices from being used to replace devices that are factory locked. The bit prevents cloning of a factory locked part and thus
ensures the security of the ESN once the product
is shipped to the field.
The system accesses the Sec2 through a command sequence (see “Enter/Exit Secured Sector
Command Sequence”). After the system has written the Enter Secured Sector command sequence,
it may read the Sec2 by using the addresses normally occupied by the boot sectors, as specified
in Table 4. This mode of operation continues until
the system issues the Exit Secured Sector command sequence, or until power is removed from
the device. On power-up, or following a hardware
reset, the device reverts to addressing the boot
sectors.
Sec2 Programmed and Protected At the Factory
In a factory-locked device, the Sec2 is protected
when the device is shipped from the factory and
cannot be modified in any way. The device is available preprogrammed with one of the following:
n A random, secure ESN only
n Customer code
n Both a random, secure ESN and customer
code
In devices that have an ESN, it will be located at
the bottom of the lowest 8 Kbyte boot sector: starting at byte address 0x000000 and ending at
0x00000F for a Bottom Boot device, and starting
at byte address 0x1F0000 and ending at 0x1F000F
for a Top Boot device.

Sec2 NOT Programmed or Protected at the Factory
If the security feature is not required, the Sec2 can
be treated as an additional Flash memory space
of 64 Kbytes. The Sec2 can be read, programmed,
and erased as often as required. The Sec2 area
can be protected using the following procedure:
n Write the three-cycle Enter Secure Sector Region command sequence
n Then follow the sector protect algorithm shown
in Figure 1, except that RESET# may be at
either VIH or VID. This allows in-system protection of the Secure Sector without raising any
device pin to a high voltage. Note that this
method is only applicable to the Secure Sector.
n Once the Secure Sector is locked and verified,
the system must write the Exit Secure Sector
command sequence to return to reading and
writing the remainder of the array.
Sec2 protection must be used with caution since,
once protected, there is no procedure available
for unprotecting the Sec2 area and none of the
bits in the Sec2 memory space can be modified in
any way.
BUS OPERATIONS
Device bus operations are initiated through the
internal command register, which consists of sets
of latches that store the commands, along with
the address and data information, if any, needed
to execute the specific command. The command
register itself does not occupy any addressable
memory location. The contents of the command
register serve as inputs to an internal state machine whose outputs control the operation of the
device. Table 5 lists the normal bus operations,
the inputs and control levels they require, and the
resulting outputs. Certain bus operations require
r1.3/Apr 01
a high voltage on one or more device pins. Those
are described in Table 6.
Read Operation
Data is read from the HY29DS16x by using standard microprocessor read cycles while placing the
byte or word address on the device’s address inputs. The host system must drive the CE# and
OE# pins Low and drive WE# High for a valid read
operation to take place. The BYTE# pin determines whether the device outputs array data in
words (DQ[15:0]) or in bytes (DQ[7:0]).

r1.3/Apr 01
HY29DS162/HY29DS163
The HY29DS16x is automatically set for reading
array data after device power-up and after a hardware reset to ensure that no spurious alteration of
the memory content occurs during the power transition. No command is necessary in this mode to
obtain array data, and both banks of the device
remain enabled for read accesses until the command register contents are altered.
This device features the capability of reading data
from one bank of the memory while a program or
erase operation is in progress in the other bank.
If the host reads from an address within an erasing or erase-suspended sector, or from a bank
where a programming operation is taking place,
the device outputs status data instead of array data
(see Write Operation Status section). After completing an Automatic Program or Automatic Erase
algorithm within a bank, that bank automatically
returns to the read array data mode.
When the host issues an Erase Suspend command, the bank specified in the command enters
the Erase- Suspended Read mode. While in that
mode, the host can read data from, or program
data into, any sector in that bank except the
sector(s) being erased. After completing a programming operation in the Erase Suspend mode,
the system may once again read array data with
the same exception noted above.
The host must issue a hardware reset or the software reset command to return a sector to the read
array data mode if DQ[5] goes high during a program or erase cycle, or to return the device to the
read array data mode while it is in the Electronic
ID mode.
Write Operation
Certain operations, including programming data
and erasing sectors of memory, require the host
to write a command or command sequence to the
HY29DS16x. Writes to the device are performed
by placing the byte or word address on the device’s
address inputs while the data to be written is input
on DQ[15:0] (BYTE# = High) or DQ[7:0] (BYTE#
= Low). The host system must drive the CE# and
WE# pins Low and drive OE# High for a valid write
operation to take place. All addresses are latched
on the falling edge of WE# or CE#, whichever
happens later. All data is latched on the rising
edge of WE# or CE#, whichever happens first.
r1.3/Apr 01
The “Device Commands” section of this data sheet
provides details on the specific device commands
implemented in the HY29DS16x.
Accelerated Program Operation
This device offers improved performance for programming operations through the ‘Accelerate
(ACC)’ function. This is one of two functions provided by the WP#/ACC pin and is intended primarily to allow faster manufacturing throughput at the
factory.
If VHH is applied to this input, the device enters the
Unlock Bypass mode, temporarily unprotects any
protected sectors, and uses the higher voltage on
the pin to reduce the time required for program
operations. The host system would then use the
two-cycle program command sequence as required by the Unlock Bypass mode. Removing
VHH from the pin returns the device to normal operation.
This pin must not be at VHH for operations other
than accelerated programming, or device damage
may result. Leaving the pin floating or unconnected may result in inconsistent device operation.
Write Protect Function
The Write Protect function provides a hardware
method of protecting certain boot sectors without
using VID. This is the second function provided by
the WP#/ACC pin.
Placing this pin at VIL disables program and erase
operations in two of the eight 8 Kbyte (4 Kword)
boot sectors. The affected sectors are sectors S0
and S1 in a bottom-boot device, or S37 and S38
in a top-boot device. If the pin is placed at VIH, the
protection state of those two sectors reverts to
whether they were last set to be protected or unprotected using the method described in the Sector Group Protection and Unprotection sections.
Standby Operation
When the system is not reading or writing to the
device, it can place the device in the Standby
mode. In this mode, current consumption is greatly
reduced, and the data bus outputs are placed in
the high impedance state, independent of the OE#
input. The Standby mode can invoked using two
methods.
11
HY29DS162/HY29DS163
The device enters the CE# controlled Deep
Standby mode when the CE# and RESET# pins
are both held at VCC ± 0.3V. Note that this is a
more restricted voltage range than VIH. If both CE#
and RESET# are held at VIH , but not within VCC ±
0.3V, the device will be in the Normal Standby
mode, but the standby current will be greater.
The device enters the RESET# controlled Deep
Standby mode when the RESET# pin is held at
VSS ± 0.3V. If RESET# is held at VIL but not within
VSS ± 0.3V, the standby current will be greater.
See RESET# section for additional information on
the reset operation.
The device requires standard access time (tCE) for
read access when the device is in any of the
standby modes, before it is ready to read data. If
the device is deselected during erasure or programming, it continues to draw active current until
the operation is completed.
Sleep Mode
The Sleep mode automatically minimizes device
power consumption. This mode is automatically
entered when addresses remain stable for tACC +
30 ns (typical) and is independent of the state of
the CE#, WE#, and OE# control signals. Standard address access timings provide new data
when addresses are changed. While in Sleep
mode, output data is latched and always available
to the system.
NOTE: Sleep mode is entered only when the device is
in Read mode. It is not entered if the device is executing
an automatic algorithm, if it is in erase suspend mode,
or during receipt of a command sequence.
Output Disable Operation
When the OE# input is at VIH, output data from the
device is disabled and the data bus pins are placed
in the high impedance state.
Reset Operation
The RESET# pin provides a hardware method of
resetting the device to reading array data. When
the RESET# pin is driven low for the minimum
specified period, the device immediately terminates any operation in progress, tri-states the data
bus pins, and ignores all read/write commands for
the duration of the RESET# pulse. The device also
resets the internal state machine to reading array
data. If an operation was interrupted by the as12
sertion of RESET#, it should be reinitiated once
the device is ready to accept another command
sequence to ensure data integrity.
Current is reduced for the duration of the RESET#
pulse as described in the Standby Operation section above.
If RESET# is asserted during a program or erase
operation, the RY/BY# pin remains Low (busy) until
the internal reset operation is complete, which requires a time of tREADY (during Automatic Algorithms). The system can thus monitor RY/BY# to
determine when the reset operation completes,
and can perform a read or write operation tRB after
RY/BY# goes High. If RESET# is asserted when
a program or erase operation is not executing (RY/
BY# pin is High), the reset operation is completed
within a time of tRP. In this case, the host can perform a read or write operation tRH after the RESET# pin returns High .
The RESET# pin may be tied to the system reset
signal. Thus, a system reset would also reset the
device, enabling the system to read the boot-up
firmware from the Flash memory.
Sector Group Protect Operation
The hardware sector group protection feature disables both program and erase operations in any
combination of sector groups. A sector group consists of a single sector or a group of adjacent sectors, as specified in Tables 7 and 8. This function
can be implemented either in-system or by using
programming equipment. It requires a high voltage (VID) on the RESET# pin and uses standard
microprocessor bus cycle timing to implement
sector protection. The flow chart in Figure 1 illustrates the algorithm.
The HY29DS16x is shipped with all sector groups
unprotected. It is possible to determine whether
a sector is protected or unprotected. See the Electronic ID Mode section for details.
Sector Unprotect Operation
The hardware sector unprotection feature re-enables both program and erase operations in previously protected sector groups. This function can
be implemented either in-system or by using programming equipment. Note that to unprotect any
sector, all unprotected sector groups must first be
protected prior to the first sector unprotect write

cycle. Also, the unprotect procedure will cause
all sectors to become unprotected, thus, sector
groups that require protection must be protected
again after the unprotect procedure is run.
Electronic ID Operation (High Voltage Method)
The Electronic ID mode provides manufacturer and
device identification, sector protection verification
and Sec2 region protection status through identifier codes output on DQ[7:0]. This mode is intended primarily for programming equipment to automatically match a device to be programmed with
its corresponding programming algorithm.
This procedure requires VID on the RESET# pin
and uses standard microprocessor bus cycle timing to implement sector unprotection. The flow
chart in Figure 2 illustrates the algorithm.
Two methods are provided for accessing the Electronic ID data. The first requires VID on address
pin A[9], with additional requirements for obtaining specific data items listed in Table 6. The Electronic ID data can also be obtained by the host
through specific commands issued via the command register, as described later in the ‘Device
Commands’ section of this data sheet.
Temporary Sector Unprotect Operation
This feature allows temporary unprotection of protected sectors to allow changing the data in-system. Temporary Sector Unprotect mode is activated by setting the RESET# pin to VID. While in
this mode, formerly protected sectors can be programmed or erased by invoking the appropriate
commands (see Device Commands section).
Once VID is removed from RESET#, all the previously protected sector groups are protected again.
Figure 3 illustrates the algorithm.
While in the high-voltage Electronic ID mode, the
system may read at specific addresses to obtain
certain device identification and status information:
NOTE: If WP#/ACC = VIL, the two outermost boot sectors remain protected.
n A read cycle at address 0xXXX00 retrieves the
manufacturer code.
n A read cycle at address 0xXXX01 in word mode
or 0xXXX02 in byte mode returns the device
code.

DEVICE COMMANDS
Device operations are initiated by writing designated address and data command sequences into
the device. Addresses are latched on the falling
edge of WE# or CE#, whichever happens later.
Data is latched on the rising edge of WE# or CE#,
whichever happens first.
A command sequence is composed of one, two
or three of the following sub-segments: an unlock
cycle, a command cycle and a data cycle. Table
9 summarizes the composition of the valid command sequences implemented in the HY29DS16x,
and these sequences are fully described in Table
10 and in the sections that follow.
Writing incorrect address and data values or writing them in the improper sequence resets the
HY29DS16x to the Read mode.
Reading Data
The device automatically enters the Read mode
after device power-up, after the RESET# input is
asserted and upon the completion of certain commands. Commands are not required to retrieve
data in this mode. See Read Operation section
for additional information.

Legend and notes for Table 10:
Legend:

RA/RD = Memory address/data for the read operation
PA/PD = Memory address/data for the program operation
SA = A[19:12], sector address of the sector to be erased or verified (see Note 3 and Tables 1 and 2).
BA = A[19:18] or A[19:17], depending on the device version, bank address, see Note 3 and Table 3.
Notes:
1. All values are in hexadecimal. DQ[15:8] are don’t care for unlock and command cycles.
2. All bus cycles are write operations unless otherwise noted.
3. Address is A[10:0] in Word mode and A[10:0, -1] in Byte mode. A[19:11] are don’t care except as follows:
• For RA and PA, A[19:11] are the upper address bits of the byte to be read or programmed.
• Where ‘SA’ is indicated, A[19:12] are the sector address.
• Where ‘BA’ is indicated, A[19:18] or A[19:17], depending on the device version, are the bank address.
4. The Erase Suspend command is valid only during a sector erase operation. The system may read and program in nonerasing sectors, or enter the Electronic ID mode, while in the Erase Suspend mode.
5. The Erase Resume command is valid only during the Erase Suspend mode.
6. The fourth bus cycle is a read cycle.
7. The command is required only to return to the Read mode when the device is in the Electronic ID command mode or in
the CFI Query mode. It must also be issued to return to read mode if DQ[5] goes High during a program or erase
operation. It is not required for normal read operations.
8 This command is valid only when the device is in Read mode or in Electronic ID mode.
9. The Unlock Bypass command is required prior to the Unlock Bypass Program command.
As described above, a Reset command is not normally required to begin reading array data. However, a Reset command must be issued in order
to read array data in the following cases:
n If the device is in the Electronic ID mode, a
Reset command must be written to return to
the Read mode. If the device was in the Erase
Suspend mode when the device entered the
Electronic ID mode, writing the Reset command
returns the device to the Erase Suspend mode.
Note: When in the Electronic ID bus operation mode,
the device returns to the Read mode when VID is removed from the A[9] pin. The Reset command is not
required in this case.
n If the device is in the CFI Query mode, a Reset
command must be written to return to the array Read mode.
n If DQ[5] (Exceeded Time Limit) goes High during a program or erase operation, a Reset command must be invoked to return the sectors to
the Read mode (or to the Erase Suspend mode
if the device was in Erase Suspend when the
Program command was issued).
The Reset command may also be used to abort
certain command sequences:
n In a Sector Erase or Chip Erase command sequence, the Reset command may be written
at any time before erasing actually begins, including, for the Sector Erase command, ber1.3/Apr 01
tween the cycles that specify the sectors to be
erased (see Sector Erase command description). This aborts the command and resets the
device to the Read mode. Once erasure begins, however, the device ignores the Reset
command until the operation is complete.
n In a Program command sequence, the Reset
command may be written between the sequence cycles before programming actually begins. This aborts the command and resets the
device to the Read mode, or to the Erase Suspend mode if the Program command sequence
is written while the device is in the Erase Suspend mode. Once programming begins, however, the device ignores the Reset command
until the operation is complete.
n The Reset command may be written between
the cycles in an Electronic ID command sequence to abort that command. As described
above, once in the Electronic ID mode, the
Reset command must be written to return to
the array Read mode.
Enter /Exit Sec2 Command Sequence
The system can access the Sec2 region of the
device by issuing the Enter Sec2 Region command
sequence. The device continues to access the
Sec2 region until the system issues the Exit Sec2
Region command sequence, which returns the
device to normal operation.
17
HY29DS162/HY29DS163
Note: A hardware reset will reset the device to the read
array mode.
Program Command
The system programs the device a word or byte
at a time by issuing the appropriate four-cycle Program command sequence, as shown in Table 10.
The sequence begins by writing two unlock cycles,
followed by the program setup command and,
lastly, the program address and data. This initiates the Automatic Program algorithm that automatically provides internally generated program
pulses and verifies the programmed cell margin.
The host is not required to provide further controls or timings during this operation. When the
Automatic Program algorithm is complete, that
bank returns to the Read mode. Several methods are provided to allow the host to determine
the status of the programming operation, as described in the Write Operation Status section.
While the Automatic Program algorithm is in
progress in one bank, the host may read data from
the non-programming bank.
Commands written to the device during execution
of the Automatic Program algorithm are ignored.
Note that a hardware reset immediately terminates
the programming operation. To ensure data integrity, the aborted program command sequence
should be reinitiated once the reset operation is
complete.
Programming is allowed in any sequence. Only
erase operations can convert a stored ‘0’ to a ‘1’.
Thus, a bit cannot be programmed from a ‘0’ back
to a ‘1’. Attempting to do so may cause that bank
to halt the operation and set DQ[5] to ‘1’, or cause
the Data# Polling algorithm to indicate the operation was successful. However, a succeeding read
will show that the data is still ‘0’.
Unlock Bypass/Bypass Program/Bypass Reset
Commands
Unlock Bypass provides a faster method than the
normal Program command for the host system to
program bytes or words to a bank. As shown in
Table 10, the Unlock Bypass command sequence
consists of two unlock write cycles followed by a
third write cycle containing the Unlock Bypass
command, 0x20. That bank then enters the Unlock Bypass mode. In this mode, a two-cycle Unlock Bypass Program command sequence is used
18
instead of the standard four-cycle program sequence to invoke a programming operation. The
first cycle in this sequence contains the Unlock
Bypass Program command, 0xA0, and the second cycle specifies the program address and data,
thus eliminating the initial two unlock cycles required in the standard Program command sequence. Additional data is programmed in the
same manner.
During the Unlock Bypass mode, only the Unlock
Bypass Program and Unlock Bypass Reset commands are valid. To exit the Unlock Bypass mode,
the host must issue the two-cycle Unlock Bypass
Reset command sequence shown in Table 10.
The bank specified in the first cycle of that command then returns to the Read array data mode.
Figure 4 illustrates the procedures for the normal
and Unlock Bypass program operations.
Note: The device automatically enters the Unlock Bypass mode when it is placed in Accelerate mode via the
WP#/ACC pin.
Chip Erase Command
The Chip Erase command sequence consists of
two unlock cycles, followed by a set-up command,
two additional unlock cycles and then the Chip
Erase command. This sequence invokes the Automatic Erase algorithm that automatically
preprograms (if necessary) and verifies the entire
memory for an all zero data pattern prior to electrical erase. The host system is not required to
provide any controls or timings during these operations.
If all sectors in the device are protected, the device returns to reading array data after approximately 100 µs. If at least one sector is unprotected, the erase operation erases the unprotected
sectors, and ignores the command for the sectors
that are protected. However, even if every sector
in one of the banks is protected, reads from that
bank are not permitted until the completion of the
Automatic Erase algorithm for the unprotected
sectors in the other bank.
Commands written to the device during execution
of the Automatic Erase algorithm are ignored. Note
that a hardware reset immediately terminates the
chip erase operation. To ensure data integrity,
the aborted Chip Erase command sequence
should be reissued once the reset operation is
complete.

mand, two additional unlock cycles and then the
Sector Erase command, which specifies which
sector is to be erased. This sequence invokes
the Automatic Erase algorithm that automatically
preprograms (if necessary) and verifies the specified sector for an all zero data pattern prior to electrical erase. The host system is not required to
provide any controls or timings during these operations.
After the sector erase data cycle (the sixth cycle)
of the command sequence is issued, a sector
erase time-out of 50 µs (min) begins, measured
from the rising edge of the final WE# pulse in the
command sequence. During this time, an additional sector address and sector erase data cycle
may be written into an internal sector erase buffer.
This buffer may be loaded in any sequence, and
the number of sectors designated for erasure may
be from one sector to all sectors. The only restriction is that the time between these additional
cycles must be less than 50 µs, otherwise erasure may begin before the last address and command are accepted. To ensure that all commands
are accepted, it is recommended that host processor interrupts be disabled during the time that
Figure 5. Chip Erase Procedure
r1.3/Apr 01

HY29DS162/HY29DS163
the additional sector erase commands are being
issued and then be re-enabled afterwards.
The system can monitor DQ[3] to determine if the
50 µs sector erase time-out has expired, as described in the Write Operation Status section. If
the time between additional sector erase commands can be assured to be less than the timeout, the system need not monitor DQ[3].
Any command other than Sector Erase or Erase
Suspend during the time-out period resets the
bank(s) to reading array data. The system must
then rewrite the command sequence, including any
additional sector addresses. Once the sector
erase operation itself has begun, only the Erase
Suspend command is valid. All other commands
are ignored.
As for the Chip Erase command, note that a hardware reset immediately terminates the erase operation. To ensure data integrity, the aborted Sector Erase command sequence should be reissued
once the reset operation is complete.
If all sectors designated for erasing are protected,
the device returns to reading array data after approximately 100 µs. If at least one designated
sector is unprotected, the erase operation erases
the unprotected sectors, and ignores the command
for the sectors that are protected. If sectors in a
bank are designated for erasure, read array operations from that bank cannot take place until the
Automatic Erase algorithm terminates, even if all
of those sectors are protected. However, the
HY29DS16x’s simultaneous read feature allows
data to be read from a bank that does not contain
any sectors that are designated for erasure while
the erase algorithm is in progress in the other bank.
When the Automatic Erase algorithm is complete,
the device returns the erased sector(s) to the Read
array data mode. Several methods are provided
to allow the host to determine the status of the
erase operation, as described in the Write Operation Status section.
Figure 6 illustrates the sector erase procedure.
Erase Suspend/Erase Resume Commands
The Erase Suspend command allows the system
to interrupt a sector erase operation to program

quires the bank address, causes the erase operation to be suspended in all sectors designated for
erasure in the specified bank. This command is
valid only during the sector erase operation, including during the 50 µs time-out period at the end
of the command sequence, and is ignored if it is
issued during chip erase or programming operations.
The HY29DS16x requires a maximum of 20 µs to
suspend the erase operation if the erase suspend
command is issued during active sector erasure.
However, if the command is written during the
sector erase time-out, the time-out is terminated
and the erase operation is suspended immediately.
Once the erase operation has been suspended in
the bank, the system can read array data from or
program data into any sector in that bank that is
not designated for erasure. Normal read and write
timings and command definitions apply. Reading
at any address within erase-suspended sectors
produces status data on DQ[7:0]. The host can
use DQ[7], or DQ[6] and DQ[2] together, to determine if a sector is actively erasing or is erase-suspended. See ‘Write Operation Status’ for information on these status bits.
After an erase-suspended program operation is
complete, the bank returns to the erase-suspended
read state and the host can initiate another programming operation (or read operation) within nonsuspended sectors. The host can determine the
status of a program operation during the erase-
suspended state just as in the standard programming operation.
The host may also write the Electronic ID command sequence when the bank is in the Erase
Suspend mode. The device allows reading Electronic ID codes even at addresses within erasing
sectors, since the codes are not stored in the
memory array. When the device exits the Electronic ID mode, the bank reverts to the Erase Suspend mode, and is ready for another valid operation. See the Electronic ID Command section for
more information.
The system must write the Erase Resume command to the erase-suspended bank to exit the
Erase Suspend mode and continue the sector
erase operation. Further writes of the Resume
command are ignored. Another Erase Suspend
command can be written after the device has resumed erasing.
Table 11 summarizes the erase operations in the
HY29DS16x.
Electronic ID Command
The Electronic ID mode provides manufacturer and
device identification and sector protection verification through identifier codes output on DQ[7:0].
This mode is intended primarily for programming
equipment to automatically match a device to be
programmed with its corresponding programming
algorithm.

HY29DS162/HY29DS163
Two methods are provided for accessing the Electronic ID data. The first requires VID on address
pin A[9], as described previously in the Device
Operations section.
The Electronic ID data can also be obtained by
the host through specific commands issued via
the command register, as shown in Table 10. This
method does not require VID. The Electronic ID
command sequence may be written to an address
within a bank that is in the read mode or in the
Erase Suspend mode. The command may not be
written while the device is actively programming
or erasing in the other bank.
The Electronic ID command sequence is initiated
by writing two unlock cycles, followed by a third
write cycle that contains the bank address and the
Electronic ID command. The addressed bank then
enters the Electronic ID mode, and the system may
read at any address in that bank any number of
times, without initiating another command sequence.
n A read cycle at address 0x(BA)X00, where BA
is the Bank Address, retrieves the manufacturer code.
n A read cycle at address 0x(BA)X01 in word
mode or 0x(BA)X02 in byte mode returns the
device code.
n A read cycle containing a sector address (SA)
within the designated bank in A[19:12] and the
address 0x04 in A[6:0, A-1] in byte mode, or
0x02 in A[7:0] in word mode, returns 0x01 if
that sector is protected, or 0x00 if it is unprotected.
n A read cycle at address 0x(BA)X03 in word
mode or 0x(BA)X06 in byte mode returns 0x80
if the Sec2 region is protected and locked at
the factory and 0x00 if it is not.
Array data may be read from the other bank while
the designated bank is in the Electronic ID mode.
The system must write the Reset command to exit
the Electronic ID mode and return the bank to the
normal Read mode, or to the Erase-Suspended
read mode if the bank was in that mode when the
Electronic ID command was invoked. In the latter
case, an Erase Resume command to that bank
will continue the suspended erase operation.
22
Query Command and Common Flash Interface (CFI) Mode
The HY29DS16x is capable of operating in the
Common Flash Interface (CFI) mode. This mode
allows the host system to determine the manufacturer of the device, its operating parameters, its
configuration and any special command codes that
the device may accept. With this knowledge, the
system can optimize its use of the chip by using
appropriate timeout values, optimal voltages and
commands necessary to use the chip to its full
advantage.
Two commands are employed in association with
CFI mode. The first places the device in CFI mode
(Query command) and the second takes it out of
CFI mode (Reset command). These are described
in Table 10.
The single cycle Query command is valid only
when the device is in the Read mode, including
during Erase Suspend and Standby states and
while in Electronic ID command mode, but is ignored otherwise. The command is not valid while
the HY29DS16x is in the Electronic ID bus operation mode. The command places the Bank designated in the ‘Bank Address’ field of the command
in the CFI Query mode. Array data may be read
from the other bank while the designated bank is
in the CFI Query mode. Read cycles at appropriate addresses within the designated bank while in
the Query mode provide CFI data as described
later in this section. Write cycles are ignored, except for the Reset command.
The Reset command returns the device from the
CFI mode to the array Read mode (even if it was
in the Electronic ID mode when the Query command was issued), or to the Erase Suspend mode
if the device was in that mode prior to entering
CFI mode. The Reset command is valid only when
the device is in the CFI mode and as otherwise
described for the normal Reset command.
Tables 12 - 15 specify the data provided by the
HY29DS16x during CFI mode. Data at unspecified addresses reads out as 0x00. Note that a
value of 0x00 for a data item normally indicates
that the function is not supported. All values in
these tables are in hexadecimal.

WRITE OPERATION STATUS
The HY29DS16x provides a number of facilities
to determine the status of a program or erase operation. These are the RY/BY# (Ready/Busy#)
pin and certain bits of a status word which can be
read from the device during the programming and
erase operations. Table 16 summarizes the status indications and further detail is provided in the
subsections which follow.
RY/BY# - Ready/Busy#
RY/BY# is an open-drain output pin that indicates
whether a programming or erase Automatic Algorithm is in progress or has completed. A pull-up
resistor to VCC is required for proper operation. RY/
BY# is valid after the rising edge of the final WE#
pulse in the corresponding command sequence,
including during the sector erase time-out.
If the output is Low (busy), the device is actively
erasing or programming, including programming
while in the Erase Suspend mode. If the output is
High (ready), the device has completed the operation and is ready to read array data, is in the
standby mode, or at least one bank is in the erasesuspend read mode.
DQ[7] - Data# Polling
The Data# Polling bit, DQ[7], indicates to the host
system whether an Automatic Algorithm is in
progress or completed, or whether a bank is in
Erase Suspend mode. Data# Polling is valid after
the rising edge of the final WE# pulse in the program or erase command sequence.
While a programming operation is in progress, the
device outputs the complement of the value programmed to DQ[7]. When the programming operation is complete, the device outputs the value
programmed to DQ[7]. If a program operation is
attempted within a protected sector, Data# Polling on DQ[7] is active for approximately 1 µs, then
the device returns to reading array data. The host
system must do a read at the program address to
obtain valid programming status information on this
bit.
During an erase operation, Data# Polling produces
a “0” on DQ[7]. When the erase operation is complete, or if the bank enters the Erase Suspend
mode, Data# Polling produces a “1” on DQ[7]. The
host must read at an address within any of the
non-protected sectors designated for erasure to

Notes:
1. A valid address within the bank where an Automatic algorithm is in progress is required when reading status information
except RY/BY#. For a programming operation, the address used for the read cycle should be the program address. For
an erase operation, the address used for the read cycle should be any address within a non-protected sector marked for
erasure (any address for the chip erase operation).
2. DQ[5] status switches to a ‘1’ when a program or erase operation exceeds the maximum timing limit.
3. A ‘1’ during sector erase indicates that the 50 µs time-out has expired and active erasure is in progress. DQ[3] is not
applicable to the chip erase operation.
4. Equivalent to ‘No Toggle’ because data is obtained in this state. For ‘Erase Completed’,

the final WE# pulse in the Program or Erase command sequence, including during the sector erase
time-out. The system may use either OE# or CE#
to control the read cycles.
When the system detects that DQ[7] has changed
from the complement to true data (or “0” to “1” for
erase), it should do an additional read cycle to
ensure that valid data is read on DQ[7:0] or
DQ[15:0]. This is because DQ[7] may change
asynchronously with respect to the other data bits
while Output Enable (OE#) is asserted low.
During an Automatic Program algorithm operation
(including programming while in Erase Suspend
mode), successive read cycles at any address in
the bank where the program operation is taking
place cause DQ[6] to toggle. DQ[6] stops toggling when the operation is complete. If a program address falls within a protected sector, DQ[6]
toggles for approximately 1 µs after the Program
command sequence is written, then returns to
reading array data.
Figure 7 shows the Data# Polling test algorithm.
DQ[6] - Toggle Bit I
Toggle Bit I on DQ[6] indicates whether an Automatic Program or Erase algorithm is in progress
or complete, or whether the device has entered
the Erase Suspend mode. Toggle Bit I may be
read at any address within the programming or
erasing bank and is valid after the rising edge of
While erasing, successive read cycles within any
sector designated for erasure (or any sector for
the chip erase operation) cause DQ[6] to toggle.
DQ[6] stops toggling when the erase operation is
complete or when the device is placed in the Erase
Suspend mode. The host may use DQ[2] to determine which sectors are erasing or erase-suspended (see below).

After an Erase command sequence is written, if
all the sectors designated for erasure are protected, DQ[6] toggles for approximately 100 µs,

DQ[2] toggles when the host reads at addresses
within sectors that have been designated for erasure, but cannot distinguish whether the sector is
actively erasing or is erase-suspended. DQ[6],
by comparison, indicates whether the device is
actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are designated for

sector and mode information.

HY29DS162/HY29DS163
DQ[5] - Exceeded Timing Limits
DQ[5] is set to a ‘1’ when the program or erase
time has exceeded a specified internal pulse count
limit. This is a failure condition that indicates that
the program or erase cycle was not successfully
completed. DQ[5] status is valid only while DQ[7]
or DQ[6] indicate that the Automatic Algorithm is
in progress.
The DQ[5] failure condition will also be signaled if
the host tries to program a ‘1’ to a location that is
previously programmed to ‘0’, since only an erase
operation can change a ‘0’ to a ‘1’.
For both of these conditions, the host must issue
a Reset command to return the device to the Read
mode.
DQ[3] - Sector Erase Timer
After writing a Sector Erase command sequence,
the host may read DQ[3] to determine whether or
not an erase operation has begun. When the
sector erase time-out expires and the sector erase
operation commences, DQ[3] switches from a ‘0’
to a ‘1’. Refer to the “Sector Erase Command”
section for additional information. Note that the
sector erase timer does not apply to the Chip Erase
command.
After the initial Sector Erase command sequence
is issued, the system should read the status on
DQ[7] (Data# Polling) or DQ[6] (Toggle Bit I) to
ensure that the device has accepted the command
sequence, and then read DQ[3]. If DQ[3] is a ‘1’,
the internally controlled erase cycle has begun and
all further sector erase data cycles or commands
(other than Erase Suspend) are ignored until the
erase operation is complete. If DQ[3] is a ‘0’, the
device will accept a sector erase data cycle to mark
an additional sector for erasure. To ensure that
the data cycles have been accepted, the system
software should check the status of DQ[3] prior to
and following each subsequent sector erase data
cycle. If DQ[3] is high on the second status check,
the last data cycle might not have been accepted.

HARDWARE DATA PROTECTION
The HY29DS16x provides several methods of protection to prevent accidental erasure or programming which might otherwise be caused by spurious system level signals during VCC power-up and
power-down transitions, or from system noise.
These methods are described in the sections that
follow.
Command Sequences
Commands that may alter array data require a
sequence of cycles as described in Table 10. This
provides data protection against inadvertent writes.
Low VCC Write Inhibit
To protect data during VCC power-up and powerdown, the device does not accept write cycles
when VCC is less than VLKO (typically 1.4 volts). The
command register and all internal program/erase
circuits are disabled, and the device resets to the
Read mode. Writes are ignored until VCC is greater
than VLKO. The system must provide the proper
signals to the control pins to prevent unintentional
writes when VCC is greater than VLKO.
28
Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on OE#,
CE# or WE# do not initiate a write cycle.
Logical Inhibit
Write cycles are inhibited by asserting any one of
the following conditions: OE# = VIL , CE# = VIH, or
WE# = VIH. To initiate a write cycle, CE# and WE#
must be a logical zero while OE# is a logical one.
Power-Up Write Inhibit
If WE# = CE# = VIL and OE# = VIH during power
up, the device does not accept commands on the
rising edge of WE#. The internal state machine is
automatically reset to the Read mode on powerup.
Sector Protection
Additional data protection is provided by the
HY29DS16x’s sector protect features, described
previously, which can be used to protect sensitive
areas of the Flash array from accidental or unauthorized attempts to alter the data.

stress rating only; functional operation of the device at these or any other conditions above those indicated in the
operational sections of this data sheet is not implied. Exposure of the device to absolute maximum rating conditions for
extended periods may affect device reliability.
2. Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions, input or I/O pins may undershoot VSS to
-2.0V for periods of up to 20 ns. See Figure 9. Maximum DC voltage on input or I/O pins is VCC + 0.5 V. During voltage
transitions, input or I/O pins may overshoot to VCC +2.0 V for periods up to 20 ns. See Figure 10.
3. Minimum DC input voltage on pins WP#/ACC, A[9], OE#, and RESET# is -0.5 V. During voltage transitions, A[9], OE#
and RESET# may undershoot VSS to -2.0 V for periods of up to 20 ns. See Figure 9. Maximum DC input voltage on pins
A[9], OE#, and RESET#] is +11.0 V which may overshoot to 12.5 V for periods up to 20 ns. Maximum DC input voltage
on pin WP#/ACC is +10.5 V which may overshoot to 12.0 V for periods up to 20 ns.
4. No more than one output at a time may be shorted to VSS. Duration of the short circuit should be less than one second.

Notes:
1. Not 100% tested.
2. Typical program and erase times assume the following conditions: 25 °C, VCC = 2.0 volts, 100,000 cycles. In addition,
programming typicals assume a checkerboard pattern. Maximum program and erase times are under worst case conditions of 90 °C, VCC = 1.8 volts, 100,000 cycles.
3. Excludes system-level overhead, which is the time required to execute the four-bus-cycle sequence for the Program
command. See Table 10 for further information on command sequences.
4. Excludes 0x00 programming prior to erasure. In the preprogramming step of the Automatic Erase algorithm, all bytes
are programmed to 0x00 before erasure.
5. The typical chip programming time is considerably less than the maximum chip programming time listed since most
bytes/words program faster than the maximum programming times specified. The device sets DQ[5] = 1 only If the
maximum byte/word program time specified is exceeded. See Write Operation Status section for additional information.
