DESCRIPTION

1

general purpose I/O

2

general purpose I/O; card clock generation up to 20 MHz with three times synchronous

frequency doubling (fXTAL, 1/2fXTAL, 1/4fXTAL and 1/8fXTAL)

3

supply voltage

4

ground connection

5

shut-down signal input; active LOW

6

connection for an external capacitor determining the Power-on reset pulse width

(typically 1 ms per 2 nF)

7

data input/output to/from the card (C7); 14 kΩ integrated pull-up resistor to VCC

8

card presence detection contact (active HIGH); do not connect to any external pull-up

or pull-down resistor; use with a normally open presence switch

9

card ground (C5); connect to GND in the application

10 clock to the card (C3)

11 card supply voltage (C1)

12 card reset (C2)

13 output of the DC/DC converter (low ESR 220 nF to PGND)

14 DC/DC converter capacitor connection (low ESR 220 nF between SAP and SAM)

15 DC/DC converter capacitor connection (low ESR 220 nF between SBP and SBM)

16 power input for the DC/DC converter

17 DC/DC converter capacitor connection (low ESR 220 nF between SBP and SBM)

18 ground for the DC/DC converter

19 DC/DC converter capacitor connection (low ESR 220 nF between SAP and SAM)

20 used for test purpose; connect to GND in the application

21 control signal for microcontroller; connect to VDD in the application

22 control signal for the microcontroller; leave open in the application

23 control signal for the microcontroller; leave open in the application

24 general purpose I/O

25 general purpose I/O

26 external crystal connection or input for an external clock signal

27 external crystal connection; leave open if an external clock is applied to XTAL1

28 reset input from the host (active HIGH); integrated pull-down resistor to GND

29 interrupt signal from the smart card interface; leave open in the application

30 external interrupt input or general purpose I/O; may be left open if not used

31 transmission line for serial communication with the host

32 reception line for serial communication with the host
