SPÉCIFICATIONS

Fonction PIN sur l'interface

Pin No.

Symbol

Description

No connection

PSB

Interface selection

C86

C86 selects the microprocessor type in parallel interface mode

5~9

No connection

VG is the LCD driving voltage for segment circuits.

No connection

XV0

XV0 is the LCD driving voltage for common circuits at positive frame.

V0 is the LCD driving voltage for common circuits at negative frame

15~19

No connection

VSS

Ground

VDD

Power supply

22~29

D7~D0

8-bit bi-directional data bus. Connect to the data bus of 8-bit
microprocessor. When CSB is non-active (CSB=“H”),
D[7:0] pins are high impedance.

ERD

C86	MPU Type	ERD	Description
H	6800 series	E	Read/Write control input pin. R/W=”H”: When E is “H”, D[7:0] are in output mode. R/W=”L”: Signals on D[7:0] are latched at the failing edge of E signal.
L	8080 series	/RD	Read enable input pin. When /RD is “L”, D[7:0] are in output mode.

RWR

C86	MPU Type	RWR	Description
H	6800 series	R/W	Read/Write control input pin. R/W=”H”: read. R/W=”L”: write.
L	8080 series	/WR	Write enable input pin. Signals on D[7:0] will be latched at the rising edge of /WR signal.

It determines whether the access is related to data or command

RSTB

Hardware reset input pin

CSB

Chip select input pin.
