General Description

The HT95CXXX family MCU are 8-bit high performance

RISC-like microcontrollers with built-in DTMF generator,

FSK decoder and dialer I/O which provide MCU dialer

implementation or system control features for telecom

product applications. The phone controller has a built-in

program ROM, data RAM, LCD driver and I/O lines for

high end products design. In addition, for power man-

agement purpose, it has a built-in frequency up conver-

sion circuit (32768Hz to 3.58MHz) which provides dual

system clock and four types of operation modes. For ex-

ample, it can operate with low speed system clock rate

of 32768Hz in green mode with little power consump-

tion. It can also operate with high speed system clock

rate of 3.58MHz in normal mode for high performance

operation. To ensure smooth dialer function and to

avoid MCU shut-down in extreme low voltage situation,

the dialer I/O circuit is built-in to generate hardware di-

aler signals such as on-hook, hold-line and hand-free.

Built-in real time clock and programmable frequency di-

vider are provided for additional fancy features in prod-

uct developments. The device is best suited for feature

phone products that comply with versatile dialer specifi-

cation requirements of different areas or countries.
