General Description
The HT95LXXX family MCU 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-
tions. The phone controller has a built-in program ROM,
data RAM, LCD driver and I/O lines for high end prod-
ucts design. In addition, for power management pur-
pose, it has a built-in frequency up conversion circuit
(32768Hz to 3.58MHz) which provides dual system
clock and four types of operation modes. For example, 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. 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 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 suited for feature phone
products that comply with versatile dialer specification
requirements of different areas or countries.
