HT82M9BE/HT82M9BA -- USB Mouse Encoder 8-Bit MCU
General Description
The USB MCU OTP body is suitable for USB mouse and USB joystick devices. It consists of a Holtek high performance 8-bit MCU core for control unit, built-in USB SIE,
8Kx16 ROM and 224 bytes data RAM.
The mask version HT82M9BAis fully pin and functionally compatible with the OTP version HT82M9BE device.
The HT82M9BA is under development and will be available soon.
