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-

Rev. 1.40

Application Note

Operating voltage:

Up to 0.33 s instruction cycle with 12MHz system

clock at V

Idle/Sleep mode and wake-up functions to reduce

power consumption

Oscillator types:

External high freuency Crystal -- HXT

External RC -- ERC

Internal high frequency RC -- HIRC

External low frequency crystal -- LXT

Four operational modes: Normal, Slow, Idle, Sleep

Fully integrated internal 4MHz, 8MHz and 12MHz

oscillator requires no external components

Watchdog Timer function

LIRC oscillator function for watchdog timer

All instructions executed in one or two instruction

cycles

Peripheral Features

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.
