General Description
The Cost-Effective A/D Flash Type MCU with EEPROM
Devices are a series of 8-bit high performance RISC ar-
chitecture microcontrollers, designed especially for ap-
plications 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.
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.
