January 6, 2009

General Description

The HT95R22 MCU is an 8-bit high performance, RISC

architecture microcontroller device specially designed

for telephone applications. Device flexibility is en-

hanced with its internal special features such as

power-down and wake-up functions, DTMF generator,

etc. These features combine to ensure applications re-

quire a minimum of external components and therefore

reduce overall product costs.

Having the advantages of low-power consumption,

high-performance, I/O flexibility as well as low-cost, the

device has the versatility to suit a wide range of applica-

tion possibilities such as deluxe feature phones, cord-

less phones, fax and answering machines, etc.

The device is best suited for phone products that com-

ply with versatile dialer specification requirements for

different areas or countries. The device is fully sup-

ported by the Holtek range of fully functional develop-

ment and programming tools, providing a means for fast

and efficient product development cycles.
