HT82M9AEE/HT82M9AAE -- USB Mouse Encoder 8-Bit
MCU with EEPROM
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 HT82M9AAE is fully pin and
functionally compatible with the OTPversion HT82M9AEE device. There
are two dice in the HT82M9AEE/HT82M9AAE package: one is the
HT82M9AE/HT82M9AA MCU, the other is a 128x8 bits EEPROM used for
data memory purpose. The two dice are wrie-bonded to from
HT82M9AEE/HT82M9AAE.
The HT82M9AAE is under development and will
be available soon.
