DescriptionUSB 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, 8Kx16 ROM and 224 bytes data RAM.

The mask version HT82M9BAE is fully pin and functionally compatible with the OTPversion HT82M9BEE device. There are two dice in the HT82M9BEE/HT82M9BAE package: one is the HT82M9BE/HT82M9BA MCU, the other is a 128x8 bits EEPROM used for data memory purpose. The two dice are wrie-bonded to from HT82M9BEE/HT82M9BAE.
