TMP47C834N

The TMP47C834N is designed as CMOS 4-bit microcontroller which has on-screen display circuit (OSD) to display characters and marks which indicate channel or time on TV screen, A/D converter input, D/A converter output such as TV.

TMP47C834N 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 92 basic instructions. The fourth one is 6 interrupt sources (external 2 and internal 4). The fifth one is input / output ports (30 pins). The sixth is two 12-bit timer / counters. The seventh one is serial interface with 8-bit buffer. The eighth one is watchdog timer. The ninth one is on-screen display circuit. The tenth one is D/A converter (pulse width modulation) outputs. And so on. That are the main features.

Some TMP47C834N 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 except R7 port. The fourth one is about TMP47C834N's output current (per 1 pin) which would be 3.2mA for R7, R8, R9 and would be 30mA for R6. The fifth one is about its output current total which would be 60mA. 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 TMP47C834N's operating temperature range which would be from -30°C to 70°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.
