Chip on Glass  LCD Module 240x128 - WO240128B

Technische Daten

Schnittstelle Pin-Funktion

Pin No. Symbol Beschreibung
1 ESD GND Electro-Static discharge
2 VG VG is the power of SEG-drivers
3 XV0 Negative operating voltage of COM-drivers
4 V0 Positive operating voltage of COM-drivers
5 VM VM is the non-select voltage level of COM-drivers
6 VDDA Power supply
7 VSS Ground
8 VD1 Digital power source selection
9 VDDI VDD1 is the power of interface I/O circuit
10 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)

These pins select interface operation mode

Note: Refer to “Interface Selection” for detailed information
14 RSTB Reset input pin. When RSTB is “L”, internal initialization procedure is executed
15 /RD(E) Read / Write execution control pin. (This pin is only used in parallelinterface)

This pin is not used in serial interfaces and should be connected to VDD1
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
24 /WR/(R/W) Read / Write execution control pin. (This pin is only used in parallel interface)

This pin is not used in serial interfaces and should be connected to VDD1
25 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
26 ESD GND Electro-Static discharge
