DISEGNO

Chip on Glass LCD Module 240x128 - WO240128B

Data source ref:WO240128B-TFH#

SPECIFICHE TECNICHE

Funzione dei Pin di Interfaccia

Pin No.

Simbolo

descrizione

ESD GND

Electro-Static discharge

VG is the power of SEG-drivers

XV0

Negative operating voltage of COM-drivers

Positive operating voltage of COM-drivers

VM is the non-select voltage level of COM-drivers.

VDDA

Power supply

VSS

Ground

VD1

Digital power source selection.

VDDI

VDD1 is the power of interface I/O circuit

CSB

Chip select input pin
CSB=“L”: This chip is selected and the MPU interface is active
CSB=“H”: This chip is not selected and the MPU interface is disabled
(D[7:0] are high impedance)

IF3

These pins select interface operation mode.

IF3	IF2	IF1	MPU interface type
H	H	L	80 series 8-bit parallel
H	L	L	68 series 8-bit parallel
L	H	H	8-bit serial (4-Line)
L	H	L	9-bit serial (3-Line)

IF2

IF1

RSTB

Reset input pin. When RSTB is “L”, internal initialization procedure is executed.

/RD(E)

Read / Write execution control pin. (This pin is only used in parallel interface)

MPU Type	ERD	Descriptin
6800-series	ERD	Read/Write control input pin R/W = "H" When E is "H", data bus is in output status. R/W = "L" The data are lunched at the failling edge of the E signal.
8080-series	/RD	Read enable inputpin. When /RD is "L". Data bus is in output status.

16~23

D7~D0

The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance.
If using serial interface:
D0 is the SDA signal in 4-Line & 3-Line interface.
D1 is the A0 signal in 4-Line interface

/WR/(R/W)

Read / Write execution control pin. (This pin is only used in parallel interface

MPU Type	RWR	Descriptin
6800-series	R/W	Read/Write control input pin R/W = "H" : Read R/W = "L" : write
8080-series	/WR	Write enable clock input pin. The data are layched at the rising edge of the /WR signal.

This pin is not used in serial interfaces and should be connected to VDD1

A0(SCL)

The function of this pin is different in parallel and serial interface
In parallel interface: A0 is register selection input
A0 = "H": inputs on data bus are display data
A0 = "L": inputs on data bus are command
In serial interface: this pad will be used as SCL (serial-clock) input

ESD GND

Electro-Static discharge
