VIF amplifier, Tuner and VIF-AGC, VIF-AGC detector, Frequency Phase-Locked Loop (FPLL) detector, VCO
and divider, Digital acquisition help and AFC, Video demodulator and amplifier, Sound carrier trap, SIF
amplifier, SIF-AGC detector, Single reference QSS mixer, AM demodulator, FM demodulator and acquisition
help, Audio amplifier and mute time constant, I²C-bus transceivers and MAD (module address), Internal
voltage stabilizer.
4. MULTI STANDARD SOUND PROCESSOR
The MSP34x1G family of single-chip Multistandard Sound Processors covers the sound processing of
all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip.
These TV sound processing ICs include versions for processing the multichannel television sound
(MTS) signal conforming to the standard recommended by the Broadcast Television Systems
Committee (BTSC). The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is
performed alignment free. Other processed standards are the Japanese FM-FM multiplex standard
(EIA-J) and the FM Stereo Radio standard.
Current ICs have to perform adjustment procedures in order to achieve good stereo separation for
BTSC and EIA-J. The MSP34x1G has optimum stereo performance without any adjustments.
5. 4.VIDEO SWITCH TEA6415
In case of three or more external sources are used, the video switch IC TEA6415 is used. The main
function of this device is to switch 8 video-input sources on the 6 outputs.
Each output can be switched on only one of each input. On each input an alignment of the lowest level
of the signal is made (bottom of sync. top for CVBS or black level for RGB signals).
Each nominal gain between any input and output is 6.5dB.For D2MAC or Chroma signal the alignment
is switched off by forcing, with an external resistor bridge, 5VDC on the input. Each input can be used
as a normal input or as a MAC or Chroma input (with external Resistor Bridge). All the switching
possibilities are changed through the BUS. Driving 75ohm load needs an external resistor. It is possible
to have the same input connected to several outputs.
6. AUDIO AMPLIFIER STAGE WITH TPA3002D2
The TPA3002D2 is a 9-W (per channel) efficient, Class-D audio amplifier for driving bridged-tied stereo
speakers. The TPA3002D2 can drive stereo speakersas low as 8 &. The high efficiency of the
TPA3002D2 eliminates the need for external heatsinks when playing music.

7. MAIN POWER SUPPLY (SMPS) AND POWER INTERFACE BOARD
The DC voltages required at various parts of the chassis and inverters are provided by an main power
supply unit and power interface board. The main power supply unit is designed for 24V and 12V DC
supply. Power interface board generates +12V for audio amplifier, 5V and 3.3V stand by voltage and
8V, 12V, 5V and 3V3 supplies for other different parts of the chassis.
An optocoupler is used to control the regulation of line voltage and stand-by power consumption. There
is a regulation circuit in secondary side. During the switch on period of the transistor, energy is stored in
the transformer. During the switch off period energy is fed to the load via secondary winding. By varying
switch-on time of the power transistor, it controls each portion of energy transferred to the second side
such that the output voltage remains nearly independent of load variations.
8. MICROCONTROLLER
The microprocessor is embedded inside PW181 chip which also handles scaling, frame rate conversion
and OSD generation. The on-chip 16-bit microprocessor is a Turbo x86-compatible processor core with
on-chip peripherals (timers, interrupt controller, 2-wire serial master/slave interface, UART, I/O ports,
and more). Special peripherals such as Infrared (IR) pulse decoders and a digital pulse width modulator
(PWM) are also included. There are two independent 2-wire serial master/slave interface modules that
can be multiplexed to control up to five 2-wire serial ports. The slave 2-wire interface is designed for
HDCP use only (and requires the use of HDCP Image Processors). On-chip RAM of up to 64 Kbytes is
available. A complete microprocessor system can be implemented simply by adding external ROM. The
on-chip processor can be disabled to allow external processor control of all internal functions.
9. SERIAL ACCESS CMOS 4K x 8 (32K bit) EEPROM 24C32A
The Microchip Technology Inc. 24C32A is a 4K x 8 (32K bit) Serial Electrically Erasable PROM. It has
been developed for advanced, low power applications such as personal communications or data
acquisition. The 24C32A also has a page-write capability of up to 32 bytes of data. The 24C32A is
capable of both random and sequential reads up to the 32K boundary. Functional address lines allow
up to eight 24C32A devices on the same bus, for up to 256K bits address space. Advanced CMOS
technology and broad voltage range make this device ideal for low-power/low-voltage, non-volatile code
and data applications.
10. CLASS AB STEREO HEADPHONE DRIVER TDA1308
The TDA1308 is an integrated class AB stereo headphone driver contained in a DIP8 plastic package.
The device is fabricated in a 1 mm CMOS process and has been primarily developed for portable digital
audio applications.

12.2.1. General Description
The main function of the IC is to switch 8 video input sources on 6 outputs. Each output can be
switched on only one of each input. On each input an alignment of the lowest level of the signal is made
(bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input
and output is 6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an
external resistor bridge, 5 VDC on the input. Each input can be used as a normal input or as a MAC or
Chroma input (with external resistor bridge). All the switching possibilities are changed through the
BUS. Driving 75Ω load needs an external transistor. It is possible to have the same input connected to
several outputs. The starting configuration upon power on (power supply: 0 to 10V) is undetermined. In
this case, 6 words of 16 bits are necessary to determine one configuration. In other case, 1 word of 16
bits is necessary to determine one configuration.

• 20MHz Bandwidth
• Cascadable with another TEA6415C (Internal address can be changed by pin 7 voltage)
• 8 Inputs (CVBS, RGB, MAC, CHROMA,...)
• 6 Outputs
• Possibility of MAC or chroma signal for each input by switching-off the clamp with an external resistor
bridge

12.3.4. Functional Descriptions
The 24C32A supports a Bi-directional 2-wire bus and data transmission protocol. A device that sends
data onto the bus is defined as transmitter, and a device receiving data as receiver. The bus must be
controlled by a master device which generates the Serial Clock (SCL), controls the bus access, and
generates the START and STOP conditions, while the 24C32A works as slave. Both master and slave
can operate as transmitter or receiver but the master device determines which mode is activated.

12.7. TLC7733
12.7.1. Description
The TLC77xx family of micropower supply voltage supervisors are designed for reset control, primarily
in microcomputer and microprocessor systems.
During power-on, RESET is asserted when VDD reaches 1 V. After minimum VDD (. 2 V) is established,
the circuit monitors SENSE voltage and keeps the reset outputs active as long as SENSE voltage
(VI(SENSE) )
remains below the threshold voltage. An internal timer delays return of the output to the inactive state to
ensure proper system reset. The delay time, td, is determined by an external capacitor:
td = 2.1 x 10 4 x CT
where
CT is in farads
td is in seconds
The TLC77xx has a fixed SENSE threshold voltage set by an internal voltage divider. When SENSE
voltage drops below the threshold voltage, the outputs become active and stay in that state until
SENSE voltage returns above threshold voltage and the delay time, td, has expired.
In addition to the power-on-reset and undervoltage-supervisor function, the TLC77xx adds power-down
control support for static RAM. When CONTROL is tied to GND, RESET will act as active high. The
voltage monitor contains additional logic intended for control of static memories with battery backup
during power failure. By driving the chip select (CS) of the memory circuit with the RESET output of the
TLC77xx and with the CONTROL driven by the memory bank select signal (CSH1) of the
microprocessor (see Figure 10), the memory circuit is automatically disabled during a power loss. (In
this application the TLC77xx power has to be supplied by the battery.)
The TLC77xxQ is characterized for operation over a temperature range of –40°C to 125°C, and the
TLC77xxI is characterized for operation over a temperature range of –40°C to 85°C.

The 74LVC257A is a quad 2-input multiplexer with 3-state outputs, which select 4 bits of data from two
sources and are controlled by a common data select input (S). The data inputs from source 0 (1l 0 to 4l
0 ) are selected when input S is LOW and the data inputs from source 1 (1l 1 to 4l 1 ) are selected
when S in HIGH. Data appears at the outputs (1Y to 4Y) in true (non-inverting) form from the selected
inputs. The 74LVC257A is the logic implementation of a 4-pole, 2-position switch, where the position of
the switch is determined by the logic levels applied to S. The outputs are forced to a high impedance
OFF-state when OE is HIGH.

12.14.1. General Description
The DS90C385 transmitter converts 28 bits of LVCMOS/LVTTL data into four LVDS (Low Voltage
Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the
data streams over a fifth LVDS link.
Every cycle of the transmit clock 28 bits of input data are sampled and transmitted. At a transmit clock
frequency of 85 MHz, 24 bits of RGB data and 3 bits of LCD timing and control data (FPLINE,
FPFRAME, DRDY) are transmitted at a rate of 595 Mbps per LVDS data channel. Using an 85 MHz
clock, the data throughput is 297.5 Mbytes/sec. Also available is the DS90C365 that converts 21 bits of
LVCMOS/LVTTL data into three LVDS (Low Voltage Differential Signaling) data streams. Both
transmitters can be programmed for Rising edge strobe or falling edge strobe through a dedicated pin.
A Rising edge or Falling edge strobe transmitter will interoperate with a Falling edge strobe Receiver
(DS90CF386/DS90CF366) without any translation logic.

12.15. MSP34X1G
MSP3411G
Multistandard Sound Processor Family
12.15.1. Introduction
The MSP 34x1G family of single-chip Multistandard Sound Processors covers the sound processing of
all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip. Figure shows a simplified functional block diagram of the MSP 34x1G.
The MSP 34x1G has all functions of the MSP 34x0G with the addition of a virtual surround sound
feature.
Surround sound can be reproduced to a certain extent with two loudspeakers. The MSP 34x1G
includes the Micronas virtualizer algorithm “3D-PANORAMA” which has been approved by the Dolby 1)
Laboratories for with the "Virtual Dolby Surround" technology. In addition, the MSP 34x1G includes the
“PAN-ORAMA” algorithm.
These TV sound processing ICs include versions for processing the multichannel television sound
(MTS) signal conforming to the standard recommended by the Broadcast Television Systems
Committee (BTSC). The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is
performed alignment free.
Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM Stereo
Radio standard.
Current ICs have to perform adjustment procedures in order to achieve good stereo separation for
BTSC and EIA-J. The MSP 34x1G has optimum stereo performance without any adjustments.
The MSP 34x1G has built-in automatic functions: The IC is able to detect the actual sound standard
automat-ically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can
be evaluated internally with subsequent switching between mono/stereo/bilingual; no I 2 C interaction is
necessary (Automatic Sound Selection).
Source Select
I2S bus interface consists of five pins:
1. I2S_DA_IN1, I2S_DA_IN2: For input, four channels (two channels per line, 2*16 bits) per sampling
cycle (32 kHz) are transmitted.
2. I2S _DA_OUT: For output, two channels (2*16 bits) per sampling cycle (32 kHz) are transmitted.
3. I2S _CL: Gives the timing for the transmission of I2S serial data (1.024 MHz).
4. I2S _WS: The I2S _WS word strobe line defines the left and right sample.

12.18. PI5V330
12.18.1. General Description
The PI5V330 is well suited for video applications when switching composite or RGB analog. A picturein-picture application will be described in this brief. The pixel-rate creates video overlays so two or more
pictures can be viewed at the same time. An inexpensive NTSC titler can be implemented by
superimposing the output of a character generator on a standard composite video background.
12.19. AD9883A
12.19.1. General Description
The AD9883A is a complete 8-bit, 140 MSPS, monolithic analog interface optimized for capturing RGB
graphics signals from personal computers and workstations. Its 140 MSPS encode rate capability and
full power analog bandwidth of 300 MHz supports resolutions up to SXGA (1280 × 1024 at 75 Hz).
The AD9883A includes a 140 MHz triple ADC with internal 1.25 V reference, a PLL, and programmable
gain, offset, and clamp control. The user provides only a 3.3 V power supply, analog input, and Hsync
and COAST signals. Three-state CMOS outputs may be powered from 2.5 V to 3.3 V.
The AD9883A’s on-chip PLL generates a pixel clock from the Hsync input. Pixel clock output
frequencies range from 12 MHz to140 MHz. PLL clock jitter is 500 ps p-p typical at 140 MSPS. When
the COAST signal is presented, the PLL maintains its output frequency in the absence of Hsync. A
sampling phase adjustment is provided. Data, Hsync, and clock output phase relationships are
maintained. The AD9883A also offers full sync processing for composite sync and sync-on-green
applications. A clamp signal is generated internally or may be provided by the user through the CLAMP
input pin. This interface is fully programmable via a 2-wire serial interface.
Fabricated in an advanced CMOS process, the AD9883A is provided in a space-saving 80-lead LQFP
surface-mount plastic package and is specified over the –40.˚C to +85. ˚C temperature range.

A reconstructed and phase-aligned version of the Hsync input. Both the polarity
and duration of this output can be pro-grammed via serial bus registers. By
maintaining alignment with DATACK and Data, data timing with respect to
horizontal sync can always be determined.
VSOUT
Vertical Sync Output
A reconstructed and phase-aligned version of the video Vsync. The polarity of this
output can be controlled via a serial bus bit. The placement and duration in all
modes is set by the graphics transmitter.
SOGOUT
Sync-On-Green Slicer Output
This pin outputs either the signal from the Sync-on-Green slicer comparator or an
unprocessed but delayed version of the Hsync input. See the Sync Processing
Block Diagram (Figure 12) to view how this pin is connected. (Note: Besides slicing
off SOG, the output from this pin gets no other additional processing on the
AD9883A. Vsync separation is performed via the sync separator.)

For a full description of the 2-wire serial register and how it works, refer to the 2Wire Serial Control Port section.
Data Output, Red Channel
Data Output, Green Channel
Data Output, Blue Channel
The main data outputs. Bit 7 is the MSB. The delay from pixel sampling time to
output is fixed. When the sampling time is changed by adjusting the PHASE
register, the output timing is shifted as well. The DATACK and HSOUT outputs are
also moved, so the timing relationship among the signals is maintained. For exact
timing information, refer to Figures 7, 8, and 9.
Data Output Clock
This is the main clock output signal used to strobe the output data and HSOUT into
external logic. It is produced by the internal clock generator and is synchronous
with the internal pixel sampling clock. When the sampling time is changed by
adjusting the PHASE register, the output timing is shifted as well. The Data,
DATACK, and HSOUT outputs are all moved, so the timing relationship among the
signals is maintained.
Analog Input for Red Channel
Analog Input for Green Channel
Analog Input for Blue Channel
High impedance inputs that accept the Red, Green, and Blue channel graphics
signals, respectively. (The three channels are identical, and can be used for any
colors, but colors are assigned for convenient reference.) They accommodate
input signals ranging from 0.5 V to 1.0 V full scale. Signals should be ac-coupled to
these pins to support clamp operation.
HSYNC
Horizontal Sync Input
This input receives a logic signal that establishes the horizontal timing reference
and provides the frequency reference for pixel clock generation. The logic sense of
this pin is controlled by serial register 0EH Bit 6 (Hsync Polarity). Only the leading
edge of Hsync is active; the trailing edge is ignored. When Hsync Polarity = 0, the
falling edge of Hsync is used. When Hsync Polarity = 1, the rising edge is active.
The input includes a Schmitt trigger for noise immunity, with a nominal input
threshold of 1.5 V.
VSYNC
Vertical Sync Input
This is the input for vertical sync.
SOGIN
Sync-on-Green Input
This input is provided to assist with processing signals with embedded sync,
typically on the Green channel. The pin is connected to a high speed comparator
with an internally generated threshold. The threshold level can be programmed in
10 mV steps to any voltage between 10 mV and 330 mV above the negative peak
25
32” TFT TV Service Manual
26/07/2005
of the input signal. The default voltage threshold is 150 mV. When connected to an
ac-coupled graphics signal with embedded sync, it will produce a noninverting
digital output on SOGOUT. (This is usually a composite sync signal, containing
both vertical and horizontal sync infor mation that must be separated before
passing the horizontal sync signal to Hsync.) When not used, this input should be
left unconnected. For more details on this function and how it should be
configured, refer to the Sync-on-Green section.
CLAMP
External Clamp Input
This logic input may be used to define the time during which the input signal is
clamped to ground. It should be exercised when the reference dc level is known to
be present on the analog input channels, typically during the back porch of the
graphics signal. The CLAMP pin is enabled by setting control bit Clamp Function to
1, (register 0FH, Bit 7, default is 0). When disabled, this pin is ignored and the
clamp timing is determined internally by counting a delay and duration from the
trailing edge of the Hsync input. The logic sense of this pin is controlled by Clamp
Polarity register 0FH, Bit 6. When not used, this pin must be grounded and Clamp
Function programmed to 0.
COAST
Clock Generator Coast Input (Optional)
This input may be used to cause the pixel clock generator to stop synchronizing
with Hsync and continue producing a clock at its current frequency and phase.
This is useful when processing signals from sources that fail to produce horizontal
sync pulses during the vertical interval. The COAST signal is generally not
required for PC-generated signals. The logic sense of this pin is controlled by
Coast Polarity (register 0FH, Bit 3). When not used, this pin may be grounded and
Coast Polarity programmed to 1, or tied HIGH (to VD through a 10 k resistor) and
Coast Polarity programmed to 0. Coast Polarity defaults to 1 at power-up.
REF BYPASS
Internal Reference BYPASS
Bypass for the internal 1.25 V band gap reference. It should be connected to
ground through a 0.1 µF capacitor. The absolute accuracy of this reference is
±4%, and the temperature coefficient is ±50 ppm, which is adequate for most
AD9883A applications. If higher accuracy is required, an external reference may
be employed instead.
MIDSCV
Midscale Voltage Reference BYPASS
Bypass for the internal midscale voltage reference. It should be connected to
ground through a 0.1 µF capacitor. The exact voltage varies with the gain setting
of the Blue channel.
FILT
External Filter Connection
For proper operation, the pixel clock generator PLL requires an external filter.
Connect the filter shown in Figure 6 to this pin. For optimal performance, minimize
noise and parasitics on this node.
POWER SUPPLY
VD
Main Power Supply
These pins supply power to the main elements of the circuit. They should be
filtered and as quiet as possible.
VDD
Digital Output Power Supply
A large number of output pins (up to 25) switching at high speed (up to 110 MHz)
generates a lot of power supply transients (noise). These supply pins are identified
separately from the VD pins so special care can be taken to minimize output noise
transferred into the sensitive analog circuitry. If the AD9883A is interfacing with
lower voltage logic, V DD may be connected to a lower supply voltage (as low as
2.5 V) for compatibility.
PVD
Clock Generator Power Supply
The most sensitive portion of the AD9883A is the clock generation circuitry. These
pins provide power to the clock PLL and help the user design for optimal
performance. The designer should provide quiet, noise-free power to these pins.
GND
Ground
The ground return for all circuitry on-chip. It is recommended that the AD9883A be
assembled on a single solid ground plane, with careful attention given to ground
current paths.

12.20. SAA7118E
12.20.1. General Description
The SAA7118E is a video capture device for applications at the image port of VGA controllers. Philips
X-VIP is a new multistandard comb filter video decoder chip with additional component processing,
providing high quality, optionally scaled, video.
The SAA7118E is a combination of a four-channel analog preprocessing circuit including source
selection, anti-aliasing filter and ADC, an automatic clamp and gain control, a Clock Generation Circuit
(CGC), a digital multistandard decoder containing two-dimensional chrominance/luminance separation
by an adaptive comb filter and a high performance scaler, including variable horizontal and vertical up
and downscaling and a brightness, contrast and saturation control circuit.
It is a highly integrated circuit for desktop video and similar applications. The decoder is based on the
principle of line-locked clock decoding and is able to decode the colour of PAL, SECAM and NTSC
signals into ITU 601 compatible colour component values. The SAA7118E accepts CVBS or S-video
(Y/C) as analog inputs from TV or VCR sources, including weak and distorted signals as well as
baseband component signals Y-PB -PR or RGB. An expansion port (X-port) for digital video
(bidirectional half duplex, D1 compatible) is also supported to connect to MPEG or video phone codec.
At the so called image port (I-port) the SAA7118E supports 8 or 16-bit wide output data with auxiliary
reference data for interfacing to VGA controllers.
The target application for the SAA7118E is to capture and scale video images, to be provided as digital
video stream through the image port of a VGA controller, for capture to system memory, or just to
provide digital baseband video to any picture improvement processing.

12.21. TPS72501
12.21.1. General Description
The TPS725xx family of 1-A low-dropout (LDO) linear regulators has fixed voltage options available that
are commonly used to power the latest DSPs, FPGAs, and microcontrollers. An adjustable option
ranging from 1.22 V to 5.5 V is also available. The integrated supervisory circuitry provides an active
low RESET signal when the output falls out of regulation. The no capacitor/any capacitor feature allows
the customer to tailor output transient performance as needed. Therefore, compared to other regulators
capable of providing the same output current, this family of regulators can provide a stand alone power
supply solution or a post regulator for a switch mode power supply.
These regulators are ideal for higher current applications. The family operates over a wide range of
input voltages (1.8 V to 6 V) and has very low dropout (170 mV at 1-A).
Ground current is typically 210 µA at full load and drops to less than 80 µA at no load. Standby current
is less than 1 µA.
Each regulator option is available in either a SOT223–5, D (TPS72501 only), or DDPAK package. With
a low input voltage and properly heatsinked package, the regulator dissipates more power and
achieves higher efficiencies than similar regulators requiring 2.5 V or more minimum input voltage and
higher quiescent currents. These features make it a viable power supply solution for portable, battery
powered equipment.
Although an output capacitor is not required for stability, transient response and output noise are
improved with a 10-µF output capacitor.
32
32” TFT TV Service Manual
26/07/2005
Unlike some regulators that have a minimum current requirement, the TPS725 family is stable with no
output load current. The low noise capability of this family, coupled with its high current operation and
ease of power dissipation, make it ideal for telecom boards, modem banks, and other noise sensitive
applications.

12.23. PCF8591
12.23.1. General Description
The PCF8591 is a single-chip, single-supply low power 8-bit CMOS data acquisition device with four
analog inputs, one analog output and a serial I2C-bus interface.
Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of
up to eight devices connected to the I2C-bus without additional hardware. Address, control and data to
and from the device are transferred serially via the two-line bidirectional I2C-bus.
The functions of the device include analog input multiplexing, on-chip track and hold function, 8-bit
analog-to-digital conversion and an 8-bit digital-to-analog conversion. The maximum conversion rate is
given by the maximum speed of the I2C-bus.

12.27. SDRAM 4M x 16 (MT48LC4M16A2TG-75)
12.27.1. General Description
The Micron ® 64Mb SDRAM is a high-speed CMOS, dynamic random-access memory containing
67,108,864 bits. It is internally configured as a quad-bank DRAM with a synchronous interface (all
signals are registered on the positive edge of the clock signal, CLK). Each of the x4’s 16,777,216-bit
banks is organized as 4,096 rows by 1,024 columns by 4 bits. Each of the x8’s 16,777,216-bit banks is
organized as 4,096 rows by 512 columns by 8 bits. Each of the x16’s 16,777,216- bit banks is
organized as 4,096 rows by 256 columns by 16 bits.
Read and write accesses to the SDRAM are burst oriented; accesses start at a selected location and
continue for a programmed number of locations in a programmed sequence. Accesses begin with the
registration of an ACTIVE command, which is then followed by a READ or WRITE command. The
address bits registered coincident with the ACTIVE command are used to select the bank and row to be
accessed (BA0, BA1 select the bank; A0-A11 select the row). The address bits registered coincident
with the READ or WRITE command are used to select the starting column location for the burst access.
The SDRAM provides for programmable READ or WRITE burst lengths of 1, 2, 4, or 8 locations, or the
full page, with a burst terminate option. An auto precharge function may be enabled to provide a selftimed row precharge that is initiated at the end of the burst sequence.
The 64Mb SDRAM uses an internal pipelined architecture to achieve high-speed operation. This
architecture is compatible with the 2n rule of prefetch architectures, but it also allows the column
address to be changed on every clock cycle to achieve a high-speed, fully random access. Precharging
one bank while accessing one of the other three banks will hide the precharge cycles and provide
seamless, high-speed, random-access operation.
The 64Mb SDRAM is designed to operate in 3.3V memory systems. An auto refresh mode is provided,
along with a power-saving, power-down mode. All inputs and outputs are LVTTL-compatible.
SDRAMs offer substantial advances in DRAM operating performance, including the ability to
synchronously burst data at a high data rate with automatic column-address generation, the ability to
interleave between internal banks in order to hide precharge time and the capability to randomly
change column addresses on each clock cycle during a burst access.

DESCRIPTION
Clock: CLK is driven by the system clock. All SDRAM input
signals are sampled on the positive edge of CLK. CLK also
increments the internal burst counter and controls the output
registers.
Clock Enable: CKE activates (HIGH) and deactivates (LOW)
the CLK signal. Deactivating the clock provides PRECHARGE
POWER-DOWN and SELF REFRESH operation (all banks
idle), ACTIVE POWER-DOWN (row active in any bank) or
CLOCK SUSPEND operation (burst/access in progress). CKE
is synchronous except after the device enters power-down and
self refresh modes, where CKE becomes asynchronous until
after exiting the same mode. The input buffers, including CLK,
are disabled during power-down and self refresh modes,
providing low standby power. CKE may be tied HIGH.
Chip Select: CS# enables (registered LOW) and disables
(registered HIGH) the command decoder. All commands are

Input/Output Mask: DQM is an input mask signal for write
accesses and an output enable signal for read accesses. Input
data is masked when DQM is sampled HIGH during a WRITE
cycle. The output buffers are placed in a High-Z state (twoclock latency) when DQM is sampled HIGH during a READ
cycle. On the x4 and x8, DQML (Pin 15) is a NC and DQMH is
DQM. On the x16, DQML corresponds to DQ0-DQ7 and
DQMH corresponds to DQ8-DQ15. DQML and DQMH are
considered same state when referenced as DQM.
Bank Address Inputs: BA0 and BA1 define to which bank the
ACTIVE, READ, WRITE or PRECHARGE command is being
applied.
Address Inputs: A0-A11 are sampled during the ACTIVE
command (row-address A0-A11) and READ/WRITE command
(column-address A0-A9 [x4]; A0-A8 [x8]; A0-A7 [x16]; with A10
defining auto precharge) to select one location out of the
memory array in the respective bank. A10 is sampled during a
PRECHARGE command to determine if all banks are to be
precharged (A10[HIGH]) or bank selected by BA0, BA1
(A1[LOW]). The address inputs also provide the op-code
during a LOAD MODE REGISTER command.
Data Input/Output: Data bus for x16 (4, 7, 10, 13, 42, 45, 48,

12.28. FLASH 16MBit
12.28.1. Description
The M29W160E is a 16 Mbit (2Mb x8 or 1Mb x16) non-volatile memory that can be read, erased and
reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V)
supply. On power-up the memory defaults to its Read mode where it can be read in the same way
as a ROM or EPROM. The memory is divided into blocks that can be erased independently so it is
possible to preserve valid data while old data is erased. Each block can be protected independently to
prevent accidental Program or Erase commands from modifying the memory. Program and Erase
commands are written to the Command Interface of the memory. An on-chip Program/Erase Controller
simplifies the process of programming or erasing the memory by taking care of all of the special
operations that are required to update the memory contents. The end of a program or erase operation
can be detected and any error conditions identified. The command set required to control the memory is
consistent with JEDEC standards. The blocks in the memory are asymmetrically arranged, ee Figures 5
and 6, Block Addresses. he first or last 64 KBytes have been divided into our additional blocks. The 16
KByte Boot Block can be used for small initialization code to start the microprocessor, the two 8 KByte
Parameter Blocks can be used for parameter storage and the remaining 32K is a small Main Block
where the application may be stored. Chip Enable, Output Enable and Write Enable signals
control the bus operation of the memory. They allow simple connection to most microprocessors,
often without additional logic. The memory is offered TSOP48 (12 x 20mm) and TFBGA48 (0.8mm
pitch) packages. The memory is supplied with all the bits erased (set to ’1’).
