HT16C23A/HT16C23AG

RAM Mapping 56×4 / 52×8 LCD Driver Controller

General Information

The HT16C23A/HT16C23AG devices are a memory mapping and multi-function LCD controller driver. The display segments of the devices are 224 patterns (56 segments and 4 commons) or 416 patterns (52 segments and 8 commons). The software configuration feature of the devices make it suitable for multiple LCD applications including LCD modules and display subsystems. The devices communicate with most microprocessors/microcontrollers via a two-line bidirectional I²C bus.
