General Description
The HT95L100/10P are 8-bit high performance
RISC-like microcontrollers with built-in DTMF generator
and dialer I/O which provide MCU dialer implementation
or system control features for telecom product applica-
tion. The phone controller has a built-in program ROM,
data RAM, LCD driver and a maximum of 20 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 consumption. It
can also operate with high speed system clock rate of
3.58MHz in normal mode for high performance opera-
tion.ToensuresmoothdialerfunctionandtoavoidMCU
shut-down in extreme low voltage situation, the dialer
I/O circuit is built-in to generate hardware dialer signals
such as on-hook, hold-line and hand-free. Built-in real
time clock and programmable frequency divider are pro-
vided for additional fancy features in product develop-
ments. The device is best suitable for feature phone
products that comply with versatile dialer specification
requirements of different areas or countries.
