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, 4Kx5 ROM and 224 bytes data RAM.
The mask version HT82M9AAE is fully pin and functionally
compatible with the OTP version HT82M9AEE device.
There are two dice in the HT82M9AEE/HT82M9AAE
package: one is the HT82M9AE/HT82M9AA MCU, the other is a 128x bits EEPROM used for data memory
purpose. The two dice are wrie-bonded to from HT82M9AEE/HT82M9AAE.
