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.
