TMP47C655F

The TMP47C655F is designed as a high speed and high performance 4-bit single chip microcomputers based on the TLCS-470 CMOS series. It has LCD driver, DTMF generator and large capacity RAM for repertory dial, which are suitable for application in telephones.

TMP47C655F 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 92 basic instructions. The fourth one is 6 interrupt sources (external 2 and internal 4). The fifth one is input / output ports (36 pins). The sixth is two 12-bit timer / counters. The seventh one is serial interface with 8-bit buffer. The eighth one is LCD driver. The ninth one is DTMF (dual tone multi frequency) output. The tenth one is BEEP output function. And so on. That are the main features.

Some absolute maximum ratings of TMP47C655F 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 driver) 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 R7, P142, P143. 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 its 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.
