Description

WO13232A is a monochrome COG graphic LCD module made of 132 x 32 dots matrix with FPC pinout. This COG module is built-in with ST7567A IC; it supports I2C interface, viewing direction 6 o’clock, 1/33 duty, and 1/6 Bias. WO13232A module has the same outline dimension size as WG12232B / WG12232G (with PCB) but with a higher resolution.

The WO13232A is available for FSTN Positive Transflective LCD with a white LED backlight (WO13232A-TFH) and DFSTN Negative (Double film) Transmissive LCD (WO13232A-TDI). This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. The supply voltage for logic of WO13232A is 2.7V to 3.3V, the typical value of 3V.
