This manual is the SMG12864K5 liquid crystal display module user manual, which mainly introduces the product overview, main technical parameters, interface signal description, appearance size, controller interface description, instruction description, initialization process, etc.
The SMG12864K5 is a standard dot‑matrix LCD display module with a 128 × 64 pixel resolution and 0.46 × 0.46 mm dot size. It incorporates an NT7532 LCD controller and can be directly connected to an MCU for a variety of instrument and electronic device applications.
The manual provides the module’s pin‑out (SI, SCL, A0, /RES, /CS, VDD, VSS, BG), power requirements (3.6‑5.2 V, 700 µA typical, 15 mA max) and the configuration registers needed to set LCD bias, ADC select, COM voltage and display mode. Wiring diagrams and example connections to an 8051 MCU are also included. This manual is written in Chinese.
