TMP47C440AN

TMP47C440AN is a kind of 4-bit single chip microcomputer.

There are some features about TMP47C440AN as follows. First is instrution execution time which is 1.9s (at 4.2 MHz). The second is interval timer. Then is two 12-bit timers/counters (timer, event counter, and pulse width measurement mode). Next is watchdog timer. The fifth is serial interface with 4-bit buffer (external/internal clock, leading/trailing edge shift mode). The sixth is 8-bit sucessive approximate type A/D converter. The seventh is high current outputs. The eighth is hold function (battery/capacitor back-up). The last one is real time emulator which is BM47214A.

What comes next is about the TMP47C440AN absolute maximum ratings (VSS=0 V). The VDD (supply voltage) is from -0.5 to 7 V. The VIN (input voltage) is from -0.5 to VDD+0.5 V. The VOUT1 (output voltage) is from -0.5 to VDD+0.5 V excep sink open drain pin. The VOUT2 (output voltage) is from -0.5 to 10 V for ports P1, P2, R6, R9. The VOUT3 (output voltage) is from -0.5 to VDD+0.5 V for analog inputs. The IOUT1 (output current) is 30 mA for ports P1, P2. The IOUT2 (output current) is 3.2 mA for ports R6-R9. The IOUT1 (output current (total)) is 120 mA for ports P1, P2. The PD (power dissipation) is 600 mW at Topr=70. The Tstg (storage temperature) is from -55 to 125. The Topr (operating temperature) is from -30 to 70.
