Description

WEO012832M-CTP model is a 0.91″ COG Graphic OLED display with In-Cell Capacitive Touch Panel, which is made of resolution 128×32 pixels. This module is built-in with SSD7317 TDDI IC (Touch with Display Driver IC); it supports 4-Wire SPI and I2C interface. This SSD7317 IC is a Touch and Display Driver Integration IC (TDDI IC), which integrates touch and display microelectronics into a single chip for use on PMOLED panels, targeting applications including wearables, smart home appliances, and smart healthcare devices.

WEO012832M-CTP model adopted In-Cell Touch Panel technology, which supports SPI and I2C interface featuring four touch keys (areas) and one direction slide (supports right or left direction). The supply voltage for logic (VDD) is from 1.65V to 3.5V, typical value 3.3V, 1/32 driving duty, the display with 50% Checkboard current is 4mA @8.5V VCC (typical value), driving duty 1/32. This module can be operating at temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃.

The WEO012832M-CTP model OLED module features a high contrast ratio of 10,000:1, allowing for more vibrant and deeper blacks, and brighter whites. This results in enhanced image quality, sharper details, and improved readability.

SPECIFICATIONS

Interface Pin Function

No.

Symbol

Function

VCI

Power supply pin for touch analog driving. VCI must be greater than or equal to VDD.

VSS

Ground pin.

VCC

Power Supply for Display. Most positive voltage. Connect to external source.

VSL

This is segment voltage (output low level) reference pin.
When external VSL is not used, connect externally to VSS. When external VSL is used, connect with resistor and diode to ground

DCDCEN0

Enable output pin for external DCDC circuit. NC if not used

DCDCEN1

Enable input pin for external DCDC circuit. Tie low if not used.

VDD

Power supply pin for core logic operation.

This pin outputs RAM write synchronization signal.
It should be kept NC if it is not used.

DCS

This pin is the chip select input connecting to the MCU for display interface.

TCS

This pin is the chip select input connecting to the MCU for touch.

RES#

This pin is the reset signal input for display interface.

TRES

This pin is the reset signal input for touch.

This pin is Data/Command control pin for display interface.
In I2C mode, this pin acts as SA0 for slave address selection.

E/RD#

In I2C mode, this pin acts as SA1 for slave address selection.

IRQ

Interrupt signal for touch reporting.

TD0

Serial Data Input/Output and clock for Touch
In SPI mode TD2 serves as SDOUT, TD1 serves as SDIN, and TD0 serves as the serial clock SCLK.
In I2C mode TD2 and TD1 should be tied together and serve as SDA and TD0 is the serial clock SCL. External pull up resistors.

TD1

TD2

VSS

Ground pin.
