General Description

The device is an 8-bit high performance, RISC architec-

ture microcontroller devices specifically designed for

multiple I/O control product applications.

The advantages of low power consumption, I/O flexibil-

ity, timer functions, Power Down and wake-up functions,

Watchdog timer, motor driving, industrial control, con-

sumer products, subsystem controllers, etc.

There are two dice in the HT82K74EE package: one is

the HT82K74E MCU, the other is a 128

´8 bits EEPROM

used for data memory purpose. The two dice are

wire-bonded to form HT82K74EE
