Mô tả chung
The ET6621 is a 128 patterns (32×4), memory mapping, and multi-function LCD driver. The S/W configuration feature of the ET6621 makes it suitable for multiple LCD applications including LCD modules and display subsystems. Only three or four lines are required for the interface between the MCU and the ET6621. The ET6621 contains a power down command to reduce power consumption.
