General Description
The HT95AXXX 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 and 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. Built-in real time clock
and programmable frequency divider are provided for
additional fancy features in product developments. The
device is best suited for phone products that comply
with versatile dialer specification requirements of differ-
ent areas or countries.
