HT16L21中文资料RAM Mapping 32×4 LCD Driver数据手册Holtek规格书

描述 Description

The HT16L21 device is a memory mapping and multi-function LCD controller/driver. The display segments of the device are 128 patterns (32 segments and 4 commons) display. It can also support LED drive outputs on certain Segment pins. The software configuration feature of the HT16L21 device makes it suitable for multiple LCD applications including LCD modules and display subsystems. TheHT16L21 device communicates with most microprocessors/microcontrollers via a two-wire bidirectional I2C or a three-wire SPI interface.
