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.

Programmable frequency divider (PFD)
