Introduction

AI Translation

HT1621B is a peripheral device for expanding microcontroller I/O ports. Its display matrix is 32×4, making it a 128-dot memory-mapped multi-function LCD driver circuit. The software features of this device make it well suited for LCD display applications, including LCD modules and display subsystems. The interface between this device and the host controller requires only 3 or 4 ports. Power consumption can be reduced via the Power Down command.
