4.1 Interface signals

Table 4 Pin Symbol Description No. 1 CSA Chip select 1 for segment driver 1: In order to interface data for input or output. The terminals must be CSA=L, CS1=H. 2 CSB Chip select 2 for segment driver 2:In order to interface data for input or output. The terminals must be CSB=L, CS2=H. 3 VSS Ground: 0V 4 VDD Power supply voltage for internal logic (+5V) 5 V0 External negative power supply voltage for LCD driver. 6 D/I Data or instruction select input D/I = High: Display RAM data on D0-D7. D/I = Low: Instruction data on D0-D7. 7 R/W Read / Write control signal input pin. R/W = High: CPU to read data appearing at DB0 to DB7 while E=H, CSA=L & CS1=H. R/W = Low: Display data of DB0 to DB7 is written at the falling edge of E while E=H, CSA=L & CS1=H. 8 E Chip Enable. E = High: Read mode. Data appears at DB0 to DB7 as E is at high level. E = Low: Write mode. Data of DB0 to DB7 is latched at the falling edge of E. 9 DB0 Data input/output (LSB) 10 DB1 Data input/output 11 DB2 Data input/output 12 DB3 Data input/output 13 DB4 Data input/output 14 DB5 Data input/output 15 DB6 Data input/output 16 DB7 Data input/output (MSB) 17 CS1 Chip select 1 for segment driver 1: In order to interface data for input or output. The terminals must be CSA=L, CS1=H. 18 CS2 Chip select 2 for segment driver 2: In order to interface data for input or output. The terminals must be CSB=L, CS2=H. 19 RES Reset signal. When RES=L, 1.) ON / OFF register becomes set by 0. (display off) 2.) Display start line register line becomes set by 0 (Z-address 0 set, display from line 0) After releasing reset, this condition can be changed only by instruction. 20 VEE External negative power supply voltage for LCD driver 21 LED+ LED Power Supply (Anode) 22 LED- LED Power Ground (Cathode)
