General Description
These TinyPower
TM
A/D Type 8-bit high performance
RISC architecture microcontrollers are specifically, de-
signed for applications that interface directly to analog sig-
nals. The devices include an integrated multi-channel
Analog to Digital Converter, Pulse Width Modulation and
and DAC outputs.
With their fully integrated SPI and I
2
C functions, design-
ers are provided with a means of easy communication
with external peripheral hardware. The benefits of inte-
grated A/D, PWM and DAC functions, in addition to low
power consumption, high performance, I/O flexibility
and low-cost, provides the device with the versatility for
a wide range of products in the home appliance and in-
dustrial application areas. Some of these products
could include electronic metering, environmental moni-
toring, handheld instruments, electronically controlled
tools, motor driving in addition to many others.
The unique Holtek TinyPower technology also gives the
devices extremely low current consumption characteris-
tics, an extremely important consideration in the present
trend for low power battery powered applications. The
usual Holtek MCU features such as power down and
wake-up functions, oscillator options, programmable
frequency divider, etc. combine to ensure user applica-
tions require a minimum of external components.
