General Description
The ET6625 is a peripheral device specially designed for I/O type MCU used to expand the display capability. The max. display segment of the device are 512 patterns (64×8). It also supports serial interface, buzzer sound, Watchdog Timer or time base timer functions. The ET6625 is a memory mapping and multi-function LCD controller. The software configuration feature of the ET6625 make it suitable for multiple LCD applications including LCD modules and display subsystems. Only three lines are required for the interface between the MCU and the ET6625.
