HT95A40P HT95A40P

HT95A40P-- I/O Type Phone 8-Bit MCU

General Description

The HT95A40P 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 applications. The phone controller has a built-in program ROM, HT95A40P data RAM and I/O lines for high end products design. In addition, for power management purpose, HT95A40P 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, HT95A40P can operate with low speed system clock rate of 32768Hz in green mode with little power consumption. HT95A40P can also operate with high speed system clock rate of 3.58MHz in normal mode for high performance operation. HT95A40P To ensure smooth dialer function and to avoid MCU shut-down in extreme low voltage situation, HT95A40P dialer I/O circuit is built-in to generate hardware dialer signals such as on-hook, HT95A40P hold-line and hand-free. Built-in real time clock and programmable frequency divider are provided for additional fancy features in product developments. HT95A40P device is best suited for phone products that comply with versatile dialer specification requirements of different areas or countries.
