تراشه LCD کنترلر HT1623 پکیچ LQFP-100

Introduction

HT1623 is a peripheral device specially designed for I/O type MCU used to expand the display capability. The max. display segment of the device are 384 patterns (48×8). It also supports serial interface, buzzer sound, watchdog timer or time base timer functions. The HT1623 is a memory mapping and multi-function LCD controller. The software configuration feature of the HT1623 make it suitable for multiple LCD applications including LCD modules and display subsystems. Only three lines are required for the interface between the host controller and the HT1623. The HT162X series have many kinds of products that match various applications.
