General Description

These TinyPower^TMA/D Type with LCD 8-bit high perfor-

mance RISC architecture microcontrollers are specifi-

cally, designed for applications that interface directly to

analog signals and which require an LCD or LED inter-

face. The devices include an integrated multi-channel An-

alog to Digital Converter, Pulse Width Modulation outputs

and an LCD/LED driver.

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.

With their fully integrated SPI and I²C functions, design-

ers are provided with a means of easy communication

with external peripheral hardware. The benefits of inte-

grated A/D, LCD, and PWM 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

Mask type devices, the HT56C668 and HT56C678, are

also available for volume production products.
