TMP47C446ADF

The TMP47C446ADF is designed as high speed and high performance 4-bit single chip microcomputer, integrating LCD driver, the 8-bit AD converter and watchdog timer based on the TLCS-47 series.

TMP47C446ADF has many features. The first one is 4-bit single chip microcomputer. The second one is instruction execution time is 1.9us at 4.2MHz. The third one is 89 basic instructions. The fourth one is 6 interrupt sources (external 2 and internal 4). The fifth one is input / output ports (24 pins). The sixth is two 12-bit timer / counters. The seventh one is serial interface with 4-bit buffer. The eighth one is LCD driver (automatic display). The ninth one is 8-bit successive approximate type AD converter. The tenth one is dual clock operation. And so on. That are the main features.

Some absolute maximum ratings of TMP47C446ADF 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 -0.3V to Vdd+0.3V. The third one is about its input voltage which would be from -0.3V to Vdd+0.3V. The fourth 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 except R4. The fifth one is about its 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 TMP47C446ADF 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.
