HT16C21 SOP20

توضیحات محصول

The HT16C21 device is a memory mapping and multi-function LCD controller/driver. The display segments of the device are 80 patterns (20 segments and 4 commons) or 128 patterns (16 segments and 8 commons). The software configuration feature of the HT16C21 device makes it suitable for multiple LCD applications including LCD modules and display subsystems. The HT16C21 device communicates with most microprocessors/microcontrollers via a two-line bidirectional I2C interface.
