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 5. 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. lv Figure 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. ch 8.3 Shutdown Mode Te 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. 8.4 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. www.austriamicrosystems.com/LED-Driver-ICs/AS1100 Revision 1.37 6 - 16 AS1100 Datasheet - D e t a i l e d D e s c r i p t i o n 8.5 Decode-Mode Register al id 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 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 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). 8.6 Intensity Control and Interdigit Blanking lv 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 am lc s on A te G nt st il 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). Table 5.

In the test mode all LEDs are switched on at maximum brightness (duty cycle 31/32). All programming of digit and control registers are maintained. The format of the register is given in Table 13.

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. 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". Table 14.

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. al id 9.2 Selecting RSET Resistor and Using External Drivers lv 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. Table 15.

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 D7 corresponds to segment DP. Note: For a multiple-digit dot matrix, multiple AS1100 devices must be cascaded. Figure 7.
