The CS1671 is a dot‑matrix LCD column driver with 64×64‑bit display memory, 8‑bit parallel MCU interface and a 8 V‑17 V drive voltage range.
The CS1671 driver provides column driving for dot‑matrix LCD panels. It contains a built‑in 64×64‑bit (512 bytes) display memory that can be directly written by an MCU via an 8‑bit parallel interface. The device works with a complementary row driver (CS1670) to form a complete LCD control system, reducing system cost.
The manual details pin functions, command set, timing diagrams, electrical characteristics and typical application circuits. It also specifies power‑supply requirements, clock frequencies and temperature limits for reliable operation. This manual is written in Chinese.

The busy flag shows whether the circuit is processing an internal operation; a high level means the device is busy and cannot accept new data or commands, while a low level means it is ready.
