JD12232A3 graphic dot matrix liquid crystal display module user manual, which introduces the basic characteristics of the liquid crystal driver IC, module basic characteristics, appearance size, working parameters, electrical characteristics, interface description and other content.
The JD12232A3 graphics lattice LCD module is a yellow‑background, black‑text LCD with a view size of 61.00 × 18.00 mm and a 1/32 duty, 1/6 bias driving scheme. It supports 16 common lines and 61 segment outputs, providing a 2560‑bit display RAM (80 × 8 × 4 bits) and compatible MPU interfaces for 68‑series and 80‑series controllers.
The manual details the electrical characteristics, pin definitions, command set, timing diagrams for both 68‑series and 80‑series MPU interfaces, and includes an application example with an 8031 microcontroller. Instructions for resetting, setting display parameters, and entering safety mode are also provided. This manual is written in Chinese.
