TMP47C454AN

The TMP47C454AN is designed as high performance 4-bit single chip microcomputer based on the TLCS-47 CMOS series with a DTMF generator and a large-capacity RAM for repertory dialing applications, which is suitable for utilization in telephones.

TMP47C454AN has many features. The first one is 4-bit single chip microcomputer. The second one is instruction execution time is 2.1us at 3.84MHz. The third one is 90 basic instructions. The fourth one is 5 interrupt sources (external 2 and internal 3). The fifth one is input / output ports (23 pins). The sixth is two 12-bit timer / counters. The seventh one is interval timer. The eighth one is RAM for reportory dial 768 x 4 bit max. The ninth one is BEEP output function. The tenth one is hold function. And so on. That are the main features.

Some TMP47C454AN absolute maximum ratings have been concluded into several points as follow. The first one is about its supply voltage which would be from -0.3V to 7V. The second one is about its input voltage which would be from -0.3V to Vdd+0.3V. The third one is about its output voltage which would be from -0.3V to Vdd+0.3V and it would be from -0.3V to 10V for sink open drain pin. The fourth one is about TMP47C454AN's output current (per 1 pin) which would be 3.2mA. The fifth one is about its power dissipation which would be 600mW. The sixth one is about its soldering temperature which would be 260°C (10s). The seventh one is about its storage temperature range which would be from -55°C to 125°C. The eighth one is about TMP47C454AN's operating temperature range which would be from -30°C to 60°C. It should be noted that the absolute maximum ratings are rated values which must not be exceeded during operation, even for an instant. Any one of the ratings must not be exceeded. And so on.
