产品叙述

技术总览：图形 OLED 彩色显示模块

WEO012864MX 是一款高对比度的 0.96" OLED 彩色显示模块，具备 128x64 分辨率。该型号采用固定双色布局（上方黄色，下方天蓝色），为 UI 设计提供自然的视觉层次。作为 COG (Chip on Glass) 结构的图形 OLED，其厚度仅为 1.26mm，是空间受限型手持设备的理想无边框解决方案。

集成 SSD1306 与内置电源方案

集成的 SSD1306 IC 内置电荷泵（DC/DC 转换器），支持内部生成 VCC。这使得彩色 OLED 可在 3V 单电源下工作，无需外部升压电路，从而降低 BOM 成本和 PCB 复杂度。该模块支持硬件可选接口，包括 8-bit 6800/8080 并口、3/4-wire SPI 和 I2C 协议。

UI 优化： 固定双色区域（黄/天蓝）简化了数据分类，无需复杂的 RGB 编程。
简化集成： 内置升压电路允许低压逻辑源驱动高压显示。
机械效率： COG 结构减小了设备尺寸并提升了耐用性。
宽温范围： -40°C 至 +80°C 工业级工作温度。

功能说明

N.C. (GND)

Reserved Pin (Supporting Pin)
The supporting pins can reduce the influences from stresses on the function pins. These pins must be connected to external ground.

C2N

Positive Terminal of the Flying Inverting CapacitorNegative Terminal of the Flying Boost CapacitorThe charge-pump capacitors are required between the terminals. They must be floated when the converter is not used.

C2P

C1P

C1N

VBAT

Power Supply for DC/DC Converter Circuit
This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be connected to VDD when the converter is not used.

VSS

Ground of Logic Circuit
This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground.

VDD

Power Supply for Logic
This is a voltage supply pin. It must be connected to external source.

BS0

Communicating Protocol Select
These pins are MCU interface selection input. See the
following table:

	BS0	BS1	BS2
I2C	0	1	0
3-wire SPI	1	0	0
4-wire SPI	0	0	0
8-bit 68XX Parallel	0	0	1
8-bit 80XX Parallel	0	1	1

BS1

BS2

CS#

Chip Select
This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low.

RES#

Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low, initialization of the chip is executed.

D/C#

Data/Command Control
This pin is Data/Command control pin. When the pin is pulled high, the input at D7~D0 is treated as display data.
When the pin is pulled low, the input at D7~D0 will be transferred to the command register. For detail relationship to MCU interface signals, please refer to the Timing Characteristics Diagrams.
When the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is pulled low, the data at SDIN will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection.

R/W#

Read/Write Select or Write
This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it to “Low” for write mode.
When 80XX 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 CS# is pulled low.

E/RD#

Read/Write Enable or Read
This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low.
When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low.

18~25

D0~D7

Host Data Input/Output Bus
These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. When I2C mode is selected, D2 & D1 should be tired together and serve as SDAout & SDAin in application and D0 is the serial clock input SCL.

IREF

Current Reference for Brightness Adjustment
This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 30uA.

VCOMH

Voltage Output High Level for COM Signal
This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS.

VCC

Power Supply for OEL Panel
This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used.

VLSS

Ground of Analog Circuit
This is an analog ground pin. It should be connected to VSS externally.
