TMP47C233AN

The TMP47C233AN is a kind of high speed and high performance 4-bit single chip microcomputer based on the TLC-47 CMOS series with D/A converter (pulse width modulation) outputs and A/D converter input. Besides, it is suitable for use in digital tuning systems for TV sets. It is organized as 2048*8-bit ROM and 128*4-bit RAM.

There are some TMP47C233AN features as follows: (1)instruction execution time: 1.9s (at 4.2 MHz); (2)90 basic instructions; (3)table look-up instructions; (4)5-bit and 8-bit data conversion instruction; (5)subroutine nesting: 15 levels max; (6)5 interrupt sources (external: 2, internal: 3): all sources have independent latches each, and multiple interrupt control is available; (7)I/O ports (36 pins); (8)interval timer; (9)two 12-bit timer/counters: timer, event counter, and pulse width measurement mode; (10)high current outputs: LED direct drive capability (typ. 20 mA*8 bits); (11)hold function: battery/capacitor back-up; (12)real time emulator: BM47217A.

The following is about the TMP47C233AN absolute maximum ratings: (1)supply voltage, VDD: -0.5 to 7 V; (2)input voltage, VIN: -0.5 to VDD+0.5 V; (3)output voltage, VOUT: -0.5 to VDD+0.5 V when except sink open drain pin, but included R92 pin and -0.5 to 10 V when sink open drain pin except R92 pin; (4)output current (per pin), IOUT: 30 mA when ports P1, P2 and 3.2 mA when ports R5, R7, R8, R9; (5)output current (total), IOUT: 120 mA when ports P1, P2; (6)power dissipation (TOPR=70): 600 mW; (7)soldering temperature (10 sec), Tsld: 260; (8)storage temperature, Tstg: -55 to +125; (9)operating temperature, Topr: -30 to 70.
