MODULE STRUCTURE NO.PC2002AR-ASO-A 2.1 Counter Drawing *See Appendix 2.2 Interface Pin Description Pin No. Symbol Signal Description 1 VSS Power Supply (V SS =0) 2 VDD Power Supply (V DD >V SS ) 3 VO Operating voltage for LCD 4 RS Register Selection input High = Data register Low = Instruction register (for write) Busy flag address counter (for read) 5 Read/Write signal input is used to select the read/write mode R/W High = Read mode, Low = Write mode 6 E Start enable signal to read or write the data 7~10 DB0 ~ DB3 Four low order bi-directional three-state data bus lines. Use for data transfer between the MPU and the LCD module. These four are not used during 4-bit operation. 11~14 DB4 ~ DB7 Four high order bi-directional three-state data bus lines. Used for data transfer between the MPU and the LCD module. DB7 can be used as a busy flag. 15 A Power supply for LED B / L (+ ) 16 K Power supply for LED B / L (- ) Contrast Adjust V DD 2 20KΩ V O V SS 3 1 LCD MODULE
