TMP47C456ADF

The TMP47C456ADF is designed as high speed and high performance 4-bit single chip microcomputer based on the TLCS-47 CMOS series which has LCD driver, DTMF generator and large-capacity RAM for repertory dial, which is suitable for application in telephones.

TMP47C456ADF has many features. The first one is 4-bit single chip microcomputer. The second one is instruction execution time is 8.3us at 960KHz. The third one is 90 basic instructions. The fourth one is 6 interrupt sources (external 2 and internal 4). The fifth one is input / output ports (34 pins). The sixth is two 12-bit timer / counters. The seventh one is serial interface with 4-bit buffer. The eighth one is watchdog timer. The ninth one is DTMF (dual tone multi frequency) output. The tenth one is LCD driver (automatic display). And so on. That are the main features.

Some TMP47C456ADF 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 supply voltage (LCD drive) which would be from -0.5V to Vdd+0.5V. The third one is about its input voltage which would be from -0.5V to Vdd+0.5V. The fourth one is about its output voltage which would be from -0.5V to Vdd+0.5V and it would be from -0.5V to 10V for sink open drain pin. The fifth one is about TMP47C456ADF's output current (per 1 pin) which would be 3.2mA. The sixth one is about its power dissipation which would be 600mW. The seventh one is about its soldering temperature which would be 260°C (10s). The eighth one is about its storage temperature range which would be from -55°C to 125°C. The ninth one is about TMP47C456ADF'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.
