TMP47C433A

      The TMP47C433A is designed as high speed and high performance 4-bit single chip microcomputers based on the TLCS-47 CMOS series with D/A converter (pulse width modulation) outputs and A/D converter input, and are suitable application in digital tuning systems for TV sets.
      TMP47C433A has many features.The first one is that it would have 4-bit single chip microcomputer.The second one is that its instruction execution time would be 1.9us (at 4.2MHz).The third one is TMP47C433A would have 90 basic instructions.The next one is table-up instructions.The next one is subroutine nesting: 15 levels max.The next one is 5 interrupts sources.All sources have independent latches each, and multiple interrupt control is available.The next one is about its I/O port (36 pins) which means 2 ports 5 pins of input, 2 ports 8 pins of output, 6 ports 23 pins of I/O.The next one is interval timer.The next one is two 12-bit timer/counters.Timer, event counter, and pulse width measurement mode.The next one is D/A converter (pulse width modulation) outputs which means 1 channel for 14-bit resolution and 3-channel for 6-bit resolution.The next one is 3-bit A/D converter input of 1 channel.Auto frequency control signal (5-shaped curve) detection.The next one is TMP47C433A would have high current outputs which would means LED direct drive capability.The next one is TMP47C433A would have hold function which means battery/capacitor back-up.The next one is real time emulator would be BM47217A.That are all the features.
      Some absolute maximum rating have been concluded into several points as follow.The first one is about its supply voltage which would be from -0.5 to 7V.The second one is about its input voltage which would be from -0.5 to Vdd+0.5V.The third one is about its output voltage which would be from -0.5 to Vdd+0.5 V.The fourth one is about its output current which would be 30mA for ports P1, P2 and would be 3.2mA for ports R5, R7, R8, R9.The next one is about its output current (total) which would be 120mA.The next one is about its power dissipation which would be 600mW.The next one is about its soldering temperature which would be 260 (10 sec) °C.The next one is about TMP47C433A storage temperature which would be from -55°C to 125°C.The next one is about its operating temperature which would be from -30 to 70°C.And so on.For more information please contact us.
