HT82M9AE/HT82M9AA -- 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, 4Kx15 ROM and 224 bytes data RAM.

The mask version HT82M9AA is fully pin and functionally compatible with the OTP version HT82M9AE device.

The HT82M9AA is under development and will be available soon.
