TMP47C451BN

The TMP47C451BN 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 reportory dialing applications which is suitable for application in telephones.

TMP47C451BN has many features. The first one is 4-bit single chip microcomputer. The second one is instruction execution time is 16.7us at 480KHz. 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 DTMF (dual tone multi frequency) output. The ninth one is BEEP output function. The tenth one is hold function. And so on. That are the main features.

Some TMP47C451BN 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 its output current (per 1 pin) which would be 3.2mA. The fifth one is about TMP47C451BN's 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 TMP47C451BN'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.
