HT82M9BEE/HT82M9BAE -- 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, 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.
The HT82M9BAE is under development and will
be available soon.
