The Hansheng HS19264-1 LCD module user manual provides specifications, interface details, command set, wiring diagram and usage precautions.
The HS19264-1 is a 64×64‑dot LCD module with an 8‑bit parallel interface designed for M6800‑type timing. It offers low power consumption, simple command control, and optional backlight options.
The manual covers mechanical dimensions, pin‑out, electrical characteristics, timing diagrams, full command list, a sample C program for 89C52 MCU, and safety/handling guidelines for reliable operation. This manual is written in Chinese.
| Display resolution | 64×64 bits (512 bytes) |
|---|---|
| Logic supply voltage (Vcc) | 4.5 ~ 5.5 V |
| Input high level (VIH) | 2.0 ~ Vcc |
| Working frequency | 0.4 ~ 5.5 MHz |
| Backlight LED (yellow‑green side) | 4.1 V, 10 mA |
The module operates from a logic supply of 4.5 V to 5.5 V.
The module uses 20 pins: VSS (ground), VDD (+5 V), V0 (contrast), RS (register select), R/W (read/write), E (enable), DB0‑DB7 (data bus), /CS1‑/CS3 (chip selects), /RST (reset), VOUT (negative output), LEDA (backlight +).
Call the init_lcd function, which writes the initialization commands 0xC0 and 0x3F to each of the three chip sections using wr_lcd_1/2/3.
