Serially Interfaced, 8-Digit LED Driver
1 General Description
2 Key Features
The AS1100 is an LED driver for 7 segment numeric
displays of up to 8 digits. The AS1100 can be
programmed via a conventional 4 wire serial interface.
The device includes a BCD code-B decoder, a multiplex
scan circuitry, segment and display drivers, and a 64 Bit
memory. The memory is used to store the LED settings,
so that continuous reprogramming is not necessary.
Every individual segment can be addressed and
updated separately. Only one external resistor is
required to set the current through the LED display.
Brightness can be controlled either in an analog or
digital way. The user can choose the internal code-B
decoder to display numeric digits or to address each
segment directly.
The AS1100 features an extremely low shutdown
current of only 20µA and an operational current of less
than 500µA. The number of visible digits can be
programmed as well. The AS1100 can be reset by
software and an external clock can be used. Several test
modes support easy debugging.
The AS1100 is offered in a 24-pin DIP and SOIC
packages.

Description
Data input. Data is programmed into the 16Bit shift register on the rising
CLK edge
8 digit driver lines that sink the current from the common cathode of the
display. In shutdown mode the AS1100 switches the outputs to VDD.
Both GND pins must be connected.
Strobe input. With the rising edge of the LOAD signal the 16 bit of serial
data is latched into the register.
Clock input. The interface is capable to support clock frequencies up to
10MHz. The serial data is clocked into the internal shift register with the
rising edge of the CLK signal. On the DOUT pin the data is applied with the
falling edge of CLK.
Seven segment driver lines including the decimal point. When a
segment is turned off the output is connected to GND.
The current into ISET determines the peak current through the segments
and therefore the brightness.
Positive Supply Voltage (+5V)
Serial data output for cascading drivers. The output is valid after 16.5
clock cycles. The output is never set to high impedance.

8 Detailed Description
Serial-Addressing Modes
Programming of the AS1100 is done via 4 wire serial interface. A programming sequence consists of 16-bit packages.
The data is shifted into the internal 16 Bit register with the rising edge of the CLK signal. With the rising edge of the
LOAD signal the data is latched into a digital or control register depending on the address. The LOAD signal must go to
high after the 16th rising clock edge. The LOAD signal can also come later but just before the next rising edge of CLK,
otherwise data would be lost. The content of the internal shift register is applied 16.5 clock cycles later to the DOUT
pin. The data is clocked out at the falling edge of CLK. The Bits of the 16Bit-programming package are described in
Table 4. The first 4 Bits D15-D12 are don’t care, D11-D8 contain the address and D7-D0 contain the data. The first bit
is D15, the most significant bit (MSB). The exact timing is given in Figure 5.

Digit and Control Registers
The AS1100 incorporates 15 registers, which are listed in Table 5. The digit and control registers are selected via the
4Bit address word. The 8 digit registers are realized with a 64bit memory. Each digit can be controlled directly without
rewriting the whole contents. The control registers consist of decode mode, display intensity, number of scanned digits,
shutdown, display test, and reset/external clock register.
Shutdown Mode
The AS1100 features a shutdown mode, where it consumes only 20µA current. The shutdown mode is entered via a
write to register 0Ch. Then all segment current sources are pulled to ground and all digit drivers are connected to VDD,
so that nothing is displayed. All internal digit registers keep the programmed values. The shutdown mode can either be
used for power saving or for generating a flashing display by repeatedly entering and leaving the shutdown mode. The
AS1100 needs typically 250µs to exit the shutdown mode. During shutdown the AS1100 is fully programmable. Only
the display test function overrides the shutdown mode.

Initial Power-Up
After powering up the system all register are reset, so that the display is blank. The AS1100 starts the shutdown mode.
All registers should be programmed for normal operation. The default settings enable only scan of one digit, the
internal decoder is disabled, data register and intensity register are set to the minimum value.
Decode-Mode Register
In the AS1100 a BCD decoder is included. Every digit can be selected via register 09h to be decoded. The BCD code
consists of the numbers 0-9, E,H, L,P and -. In register 09h a logic high enables the decoder for the appropriate digit.
In case that the decoder is bypassed (logic low) the data Bits D7-D0 correspond to the segment lines of the AS1100. In
Table 7 some possible settings for register 09h are shown. Bit D7, which corresponds to the decimal point, is not
affected by the settings of the decoder. Logic high means that the decimal point is displayed. In Table 8 the font of the
Code B decoder is shown. In Table 9 the correspondence of the register to the appropriate segments of a 7 segment
display is shown (see Figure 6).
Intensity Control and Interdigit Blanking
Brightness of the display can be controlled in an analog way by changing the external resistor (RSET). The current,
which flows between VDD and ISET, defines the current that flows through the LEDs. The LED current is 100 times the
ISET current. The minimum value of RSET should be 9.53kΩ, which corresponds to 40mA segment current. The
brightness of the display can also be controlled digitally via register 0Ah. The brightness can be programmed in 16
steps and is shown in Table 10. An internal pulse width modulator controls the intensity of the display.
Scan-Limit Register
The scan limit register 0Bh selects the number of digits displayed. When all 8 digits are displayed the update frequency
is typically 800Hz. If the number of digits displayed is reduced, the update frequency is reduced as well. The frequency
can be calculated using 8fOSC/N, where N is the number of digits. Since the number of displayed digits influences the
brightness, the resistor RSET should be adjusted accordingly. The Table 12 shows the maximum allowed current, when
fewer than 4 digits are used. To avoid differences in brightness the scan limit register should not be used to blank
portions of the display (leading zeros).

No-Op Register (Cascading of AS1100)
The no-operation register 00h is used when AS1100s are cascaded in order to support more than 8 digit displays. The
cascading must be done in a way that all DOUT are connected to DINof the following AS1100. The LOAD and CLK
signals are connected to all devices. For a write operation for example to the fifth device the command must be
followed by four no-operation commands. When the LOAD signal finally goes to high all shift registers are latched. The
first four devices have got no-operation commands and only the fifth device sees the intended command and updates
its register.
Reset and external Clock Register
This register is addressed via the serial interface. It allows to switch the device to external clock mode (If D0=1 the
CLK pin of the serial interface operates as system clock input.) and to apply an external reset (D1). This brings all
registers (except reg. E) to default state. For standard operation the register contents should be "00h".

9 Application Information
Supply Bypassing and Wiring
In order to achieve optimal performance the AS1100 shall be placed very close to the LED display to minimize effects
of electromagnetic interference and wiring inductance. Furthermore, it is recommended to connect a 10µF electrolytic
and a 0.1µF ceramic capacitor between VDD and GND to avoid power supply ripple. Also, both GNDs must be
connected to ground.
Selecting RSET Resistor and Using External Drivers
The current through the segments is controlled via the external resistor RSET. Segment current is about 100 times the
current in ISET. The right values for ISET are given in Table 15. The maximum current the AS1100 can drive is 40mA.
If higher currents are needed, external drivers must be used. In that case it is no longer necessary that the AS1100
drives high currents. A recommended value for RSET is 47kΩ. In cases that the AS1100 only drives few digits, Table 12
specifies the maximum currents and RSET must be set accordingly. Refer to absolute maximum ratings to calculate
acceptable limits for ambient temperature, segment current, and the LED forward-voltage drop.

8x8 LED Dot Matrix Driver
The example in Figure 7 uses the AS1100 to drive an 8x8 LED dot matrix. The LED columns have common cathode
and are connected to the DIG0-7 outputs. The rows are connected to the segment drivers. Each of the 64 LEDs can be
addressed separately. The columns are selected via the digits as shown in Table 5. The decode mode register (0xX9)
has to be programmed to ‘00000000’ as stated in Table 4. The single LEDs in a column can be addressed as stated in
Table 9, where D0 corresponds to segment G and d/ to segment DP. For a multiple digit dot matrix several AS1100
have to be cascaded.

Computing Power Dissipation
The upper limit for power dissipation (PD) for the AS1100 is determined from the following equation:
PD = (VDD x 0.5mA) + (VDD - VLED)(DUTY x ISEG x N)
(EQ 1)
Where:
VDD = supply voltage
DUTY = duty cycle set by intensity register
N = number of segments driven (worst case is 8)
VLED = LED forward voltage
ISEG = segment current set by RSET
Dissipation Example:
ISEG = 40mA, N = 8, DUTY = 31/32, VLED = 1.8V at 40mA, VDD = 5.25V
PD = 5.25V(0.5mA) + (5.25V - 1.8V)(31/32 x 40mA x 8) = 1.07W
Thus, for a PDIP package θJA = +75°C/W (from Table 13), the maximum allowed ambient temperature TA is given by:
TJ,MAX = TA + PD x θJA = 150°C = TA +1.07W x 75°C/W.
Where:
TA = +69.7°C.
The TA limit for SO Packages in the dissipation example above is +59.0°C.
