Note: These are stress ratings only. Stresses exceeding the range specified under Absolute Maximum Ratings may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

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, 4K×15 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 128
8 bits EEPROM used for data memory purpose. The two dice are wrie-bonded to from HT82M9AEE/HT82M9AAE.
