Introduction

AI Translation

HT16C21A is a memory-mapped, multi-function LCD controller/driver IC. The display modes support 80 dots (20×4) or 128 dots (16×8). Its software-configurable features make it suitable for a wide range of LCD applications, including LCD modules and display subsystems. The HT16C21A communicates with most microprocessors/microcontrollers via a two-wire bidirectional I2C interface.
