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 HT82M9AAis fully pin and
functionally compatible with the OTP version HT82M9AE device.
The HT82M9AA is under development and will be
available soon.
