Description

The USB MCU HT82M99EE/HT82M99AE are 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, 2K×14 program memory and 96 bytes data RAM.

The mask version HT82M99AE is fully pin and functionally compatible with the OTP version HT82M99EE device.

There are two dice in the HT82M99EE/HT82M99AE package: one is the HT82M99EE/HT82M99AE MCU, the other is a 128×8 bits EEPROM used for data memory purpose. The two dice are wire-bonded to form HT82M99EE/HT82M99AE.
