General Description
The HT95C200/20P/300/30P are 8-bit high perfor-
mance 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 application. The phone controller
has a built-in program ROM, data RAM, LCD driver and
a maximum of 28 I/O lines for high end products design.
In addition, for power management purpose, 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 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 dialer signals such as
on-hook, hold-line and hand-free.
clock and programmable frequency divider are provided
for additional fancy features in product developments.
The device is best suitable for feature phone products
that comply with versatile dialer specification require-
ments of different areas or countries.
