HT82K94E/HT82K94A

USB Multimedia Keyboard Encoder 8-Bit MCU

Rev. 1.00

1

November 22, 2005

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 functionally

compatible with the OTP version HT82K94E device.

HT82K94A under development, available in 2Q, 2006.
