HT82K95EE/HT82K95AE

USB Multimedia Keyboard Encoder 8-Bit MCU

Rev. 1.50

1

April 13, 2012

General Description

This device is an 8-bit high performance RISC architec-

ture microcontroller designed for USB product applica-

tions. It is particularly suitable for use in products such

as keyboards. A HALT feature is included to reduce

power consumption.

The mask version HT82K95A is fully pin and function-

ally compatible with the OTP version HT82K95E device.

There are two dice in the HT82K95EE/HT82K95AE

package: one is the HT82K95E/HT82K95A MCU, the

other is a 128

´8 bits EEPROM used for data memory

purpose. The two dice are wire-bonded to from
