TMP47C423ADF

The TMP47C423ADF is designed as high speed and high performance 4-bit single chip microcomputer with LCD driver, high speed event counter and pulse output circuit based on the TLCS-47 series.

TMP47C423ADF 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 (28 pins). The sixth is two 12-bit timer / counters. The seventh one is serial interface with 4-bit buffer. The eighth one is 16 bit high speed event counter. The ninth one is hold function. The tenth one is real time emulator: BM47219A. And so on. That are the main features.

TMP47C423ADF Some absolute maximum ratings have been concluded into several points as follow. The first one is about its supply voltage which would be from -0.5V 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 its output current (per 1 pin) which would be 3.2mA except R4 and would be 30mA for R40, R41. 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 TMP47C423ADF storage temperature range which would be from -55°C to 125°C. The ninth one is about its operating temperature range which would be from -30°C to 70°C. TMP47C423ADF 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.
