Enhanced I/O Type 8-Bit OTP MCU

Rev. 1.00

April 7, 2011

General Description

The Enhanced I/O MCUs are a series of 8-bit high per-

formance, RISC architecture microcontrollers specifi-

cally designed for a wide range of applications. The

usual Holtek microcontroller features of low power con-

sumption, I/O flexibility, timer functions, oscillator op-

tions, power down and wake-up functions, watchdog

timer and low voltage reset, combine to provide devices

with a huge range of functional options while still main-

taining a high level of cost effectiveness. The fully inte-

grated system oscillator HIRC, which requires no

external components and which has three frequency

selections, opens up a huge range of new application

possibilities for these devices, some of which may in-

clude industrial control, consumer products, household

appliances subsystem controllers, etc.
