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
