HT82K94E/HT82K94A

USB Multimedia Keyboard Encoder 8-Bit MCU

Rev. 1.50

1

October 11, 2007

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 and keyboard with calculator. A HALT fea-

ture is included to reduce power consumption.

The mask version HT82K94A is fully pin and function-

ally compatible with the OTP version HT82K94E device.

The HT82K94A is under development and will be avail-

able soon.
