DESCRIPTION

1 8xC51 general purpose I/O port

2 8xC51 general purpose I/O port

3 reset input: a HIGH on this pin for 2 machine cycles while the oscillator is running, resets the

device. An internal diffused resistor connected to GNDD permits a Power-on reset using an

external capacitor connected to VDDD.

4 analog supply voltage

5 analog ground

6 pin for an external delay capacitor

7 test pin (must be left open-circuit in the application)

8 card 2 presence contact input (active HIGH or LOW by mask option)

9 data line to/from card 2 (ISO C7 contact)

10 auxiliary I/O for ISO C8 contact for card 2 (i.e. synchronous cards)

11 auxiliary I/O for ISO C4 contact for card 2 (i.e. synchronous cards)

12 card 2 reset output (ISO C2 contact)

13 card 2 output supply voltage (ISO C1 contact)

14 clock output of card 2 (ISO C3 contact)

15 ground for card 2

16 contact 2 for the step-up converter (connect a low ESR 220 nF capacitor between pins SAP

and SAM)

17 ground for the step-up converter

18 contact 4 for the step-up converter (connect a low ESR 220 nF capacitor between pins SBP

and SBM)

19 not connected

20 not connected

21 not connected

22 not connected

23 supply voltage for the step-up converter

24 contact 3 for the step-up converter (connect a low ESR 220 nF capacitor between pins SBP

and SBM)

25 contact 1 for the step-up converter (connect a low ESR 220 nF capacitor between pins SAP

and SAM)

26 output of the step-up converter

27 ground for card 1

28 clock output of card 1 (ISO C3 contact)

29 card 1 output supply voltage (ISO C1 contact)

30 card 1 reset output (ISO C2 contact)

31 auxiliary I/O for ISO C4 contact for card 1 (i.e. synchronous cards)

32 card 1 presence contact input (active HIGH or LOW by mask option)

33 auxiliary I/O for ISO C8 contact for card 1 (i.e. synchronous cards)

34 data line to and from card 1 (ISO C7 contact)

35 auxiliary interrupt input
