2.7" 128x64 COG SSD1357 OLED with Capacitive Touchscreen + PCB + Frame

Model No. REP012864U-CTP

REP012864U-CTP is a dot matrix 128x64, 2.7 inch diagonal COG OLED display with capacitive touchscreen. The capacitive touch panel has built-in IC GT911, supporting 1-point touch. The size of the active area is 2.7” diagonal with module dimension 82×47.5 mm. The additional PCB on this OLED display helps users to save time on developing PCB on their own. Also, there's an added frame with four screw holes allowing users for quick mounting.

This 128x64 OLED module has built-in SSD1357 driver IC, and boasts high contrast ratio 10,000 : 1. There are many interface options to choose from, including 8-bits 6800 and 8080 parallel, 4-line SPI, I2C interface. Logic supply voltage ranges from 2.8V-3.3V, the typical value is 3V. There are 2 emitting colors (White / Yellow) available for this OLED module and it also features grayscale. The module can operate within the range of -20℃ to +70℃; storage temperature ranges from -30℃ to +80℃.

No. Symbol Function
1 VSS This is a ground pin.
2 VDD Power supply pin for core logic operation
3 NC Reserved Pin
The N.C. pin between function pins is reserved for compatible and flexible design.
4 D/C# This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.
When 3-wire serial interface is selected, this pin must be connected to VSS.
5 R/W#
(WR#)		 This pin is read / write control input pin connecting to the MCU interface.
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW.
When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.
6 E/RD# This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal.
Read/write operation is initiated when this pin is pulled HIGH and the chip is selected.
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.
7 DB0 These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN.
When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.

15 NC No connection
16 RES# This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.
17 CS# Chip Select
This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low.
18 NC No connection
19 BS2 Communicating Protocol Select.
These pins are MCU interface selection input. See the following table:
  BS1 BS2

4-wire Serial 0 0
8-bit 8080 Parallel 1 1
8-bit 6800 Parallel 0 1
20 BS1
21 TP_SCK I2C clock signal
22 TP_SDA I2C data signal
23 TP_INT Interrupt signal, active low, asserted to request
