General Description
The Cost-Effective A/D Type MCU Devices are a series
of 8-bit high performance RISC architecture
microcontrollers, designed especially for applications
that interface directly to analog signals, such as those
from sensors. All devices include an integrated
multi-channel Analog to Digital Converter in addition to
one or two Pulse Width Modulation outputs. The usual
Holtek MCU features such as power down and wake-up
functions, oscillator options, programmable frequency
divider, etc. combine to ensure user applications require
a minimum of external components.

Cost-Effective A/D Type 8-Bit MCU
Up to 0.5 s instruction cycle with 8MHz system clock
at V
=5V
DD
4 or 6-level subroutine nesting
4 channels 8 or 9-bit resolution A/D converter
1 or 2 channel 8-bit PWM output shared with I/O lines
Bit manipulation instruction
Table read instructions
63 powerful instructions
All instructions executed in one or two machine
cycles
Low voltage reset function
Range of packaging types
The benefits of integrated A/D and PWM functions, in
addition to low power consumption, high performance,
I/O flexibility and low-cost, provide these devices with
the versatility to suit a wide range of application possibil-
ities such as sensor signal processing, motor driving, in-
dustrial control, consumer products, subsystem
controllers, etc. Many features are common to all de-
vices, however, they differ in areas such as I/O pin
count, Program Memory capacity, A/D resolution, stack
capacity and package types.
