64x32 Micro OLED Display Module 0.49-inch COG Graphic (SSD1306BZ IC)

Model No. REX006432A

The REX006432A is a 0.49-inch COG (Chip-on-Glass) micro OLED display module designed for space-constrained embedded systems. This micro OLED screen features a 64×32 dots resolution in monochrome mode and uses the SSD1306BZ driver IC with 1/32 driving duty. With its compact outline of 14.5×11.6 mm and active area of 11.18×5.58 mm, the module is ideal for applications requiring a small but sharp micro display, such as wearables, handheld instruments, and portable control units. This 64x32 OLED micro module offers two emitting color options: white and yellow.

It operates over a wide temperature range (-40°C to +80°C) with typical power consumption of only 5 mA at 7.5 V. Logic voltage ranges from 2.8 V to 3.3 V, and panel voltage from 7.0 V to 7.8 V. Thanks to its COG construction, this OLED micro display simplifies integration in compact devices while delivering stable performance.

Features of the 64x32 OLED Micro Display

Pin No. Symbol Function
1 C2N Positive Terminal of the Flying Inverting Capacitor Negative Terminal of the Flying Boost Capacitor The charge-pump capacitors are required between the terminals. They must be floated when the converter is not used.   
2 C2P
3 C1P
4 C1N
5 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.
6 NC No connection.
7 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.
8 VDD Power Supply for Logic
This is a voltage supply pin. It must be connected to external source.
9 RES# Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low, initialization of the chip is executed.
10 SCL Host Data Input/Output BusWhen 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. 
11 SDA
12 IREF This is segment output current reference pin.
When external IREF is used, a resistor should be connected between this pin and Vss to maintain the IREF current at a maximum of 30uA. When internal IREF is used, this pin should be kept NC.
13 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.
14 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.
