Serially Interfaced, 4-Digit LED Driver
1 General Description
2 Key Features
Cost effective version of AS1100 functionality for applications
The AS1105 is an LED driver for 7-segment numeric displays of up
to 4 digits. The AS1105 can be programmed via a conventional 4wire serial interface.
up to 4-Digits
10MHz Serial Interface
The device includes a BCD code-B decoder, a multiplex scan
circuitry, segment and display drivers, and a 32-bit memory. The
memory is used to store the LED settings, so that continuous
reprogramming is not necessary.
Individual LED Segment Control
Decode/No-Decode Digit Selection
20µA Low-Power Shutdown (Data Retained)
Every individual segment can be addressed and updated separately.
Only one external resistor is required to set the current through the
LED display.
Extremely low Operating Current 0.5mA in open loop
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.
Display Blanked on Power-Up
Digital and Analog Brightness Control
Drive Common-Cathode LED Display
Software Reset
The AS1105 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.
Optional External clock
20-pin SOIC Package
The AS1105 can be reset by software and an external clock can be
used. Several test modes support easy debugging.
3 Applications
AS1105 is offered in a 20-pin SOIC package.
The AS1105 is an ideal solution for Bar-Graph Displays, Industrial
Controllers, Panel Meters, LED Matrix Displays and White Goods
such as washing machines, dishwasher, etc.

8 Detailed Description
8.1 Serial-Addressing Modes
The programming of the AS1105 is done via the 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.

8.2 Digit and Control Registers
The AS1105 incorporates 12 registers, which are listed in Table 5. The digit and control registers are selected via the 4Bit address word. The 4
digit registers are realized with a 32bit 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.
8.3 Shutdown Mode
The AS1105 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 AS1105 needs typically 250µs to exit the shutdown mode. During shutdown, the
AS1105 is fully programmable. Only the display test function overrides the shutdown mode.

8.4 Initial Power-up
After powering up the system, all register are reset, so that the display is blank. The AS1105 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.
8.5 Decode-Mode Register
In the AS1105, a BCD decoder is included. Every digit can be selected via register 09h to be decoded. The BCD code consists of the numbers 09, 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 AS1105. 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 10 the correspondence of the register to the appropriate segments of a 7 segment display is
shown (see Figure 6).
8.6 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.
8.7 Scan-Limit Register
The scan limit register 0Bh selects the number of digits displayed. When all 4 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. 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).

8.8 Display Test Register
With the display test register 0Fh all LED can be tested. In the test mode all LEDs are switched on at maximum brightness (duty cycle 31/32). All
programming of digit and control registers is maintained. The format of the register is given in Table 13.

Note: The AS1105 remains in display-test mode until the display-test register is reconfigured for normal operation.
8.9 No-Op Register (Cascading of AS1105)
The no-operation register 00h is used when AS1105s are cascaded in order to support more than 4 digit displays. The cascading must be done
in a way that all DOUT are connected to DIN of the following AS1105. 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.
8.10 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
9.1 Supply Bypassing and Wiring
In order to achieve optimal performance the AS1105 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.
9.2 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 12. The maximum current the AS1105 can drive is 40mA. If higher currents are needed, external drivers must
be used. In that case it is no longer necessary that the AS1105 drives high currents. A recommended value for RSET is 47kΩ. In cases that the
AS1105 only drives few digits Table 10 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.
9.3 4x8 LED Dot Matrix Driver
The example in Figure 7 uses the AS1105 to drive an 4x8 LED dot matrix. The LED columns have common cathode and are connected to the
DIG0-3 outputs. The rows are connected to the segment drivers. Each of the 32 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 7. The single LEDs
in a column can be addressed as stated in Table 10, where D0 corresponds to segment G and D7 to segment DP. For a multiple digit dot matrix
several AS1105 have to be cascaded.

9.4 Cascading Drivers
The AS1105 can be cascaded as well. The DOUT pin must be connected to the DIN pin of the following AS1105.

Thermal Resistance (θJA)
20 Wide SO
+85°C/W
Maximum Junction Temperature (TJ) = +150°C
Maximum Ambient Temperature (TA) = +85°C
9.5 Computing Power Dissipation
The upper limit for power dissipation (PD) for the AS1105 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 4)
VLED = LED forward voltage
ISEG = segment current set by RSET
Dissipation Example:
ISEG = 40mA, N = 4, 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 4) = 0.54W
Thus, for a SO package θJA = +85ºC/W (see Table 13), the maximum allowed ambient temperature TA is given by:
TJ,MAX = TA + PD x θJA = 150ºC = TA +0.54W x 85ºC/W
(EQ 2)
Where: TA = +104ºC
