HT16C24A/HT16C24AG
RAM Mapping 72×4/68×8/60×16 LCD Driver Controller
General Information
The HT16C24A/HT16C24AG devices are a memory mapping and multi-function LCD controller driver. The display segments of the devices are 288 patterns (72 segments and 4 commons), 544 patterns (68 segments and 8 commons) or 960 patterns (60 segments and 16 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.
