Pin Assignments (Top View) 4.1 Pin Descriptions Table 1. Pin Descriptions Pin Number Pin Name Description 1 DIN Data input. Data is programmed into the 16Bit shift register on the rising CLK edge 2, 3, 5:8, 10, 11 DIG 0 : DIG 7 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. 4, 9 GND Both GND pins must be connected. 12 LOAD/CS Strobe input. With the rising edge of the LOAD signal the 16 bit of serial data is latched into the register. 13 CLK 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. 14:17, 20:23 SEGA:G, DP Seven segment driver lines including the decimal point. When a segment is turned off the output is connected to GND. 18 ISET The current into ISET determines the peak current through the segments and therefore the brightness. 19 VDD Positive Supply Voltage (+5V) 24 DOUT Serial data output for cascading drivers. The output is valid after 16.5 clock cycles. The output is never set to high impedance. 11 12 13 14 15 16 17 18 19 20 21 22 23 DIG4 AS1100 10 1 2 3 4 5 6 7 8 9 24 DOUT DIN DIG0 GND DIG6 DIG2 GND DIG3 LOAD SEG D SEG DP SEG E SEG C VDD ISET SEG G SEG B SEG F SEG A CLK DIG7 DIG5 DIG1 |
