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, 8K´16 ROM and 224 bytes data RAM.

There are two dice in the HT82M9BEE/HT82M9BAE

package: one is the HT82M9BE/HT82M9BA MCU, the

other is a 128´8 bits EEPROM used for data memory

purpose. The two dice are wrie-bonded to from

HT82M9BEE/HT82M9BAE.

The mask version HT82M9BAE is fully pin and function-

ally compatible with the OTP version HT82M9BEE device.
