VSEL0
Input
Allows selecting card VCC power supply voltage mode (5V/3V or 1.8V/3V)
VSEL0 = Low; CVCC = 5 V when VSEL1 = High or 3 V when VSEL1 = Low
VSEL0 = High; CVCC = 1.8 V when VSEL1 = High or 3 V when VSEL1 = Low

VDDP
Power
Regulator power supply.
3
PRES
Input
Card presence pin active (card present) when PRES = Low. A builtin debounce timer of
about 8 ms is activated when a card is inserted. Convenient for Normally Open (NO)
Smart card connector.
4
PRES
Input
Card presence pin active (card present) when PRES = High. A builtin debounce timer of
about 8 ms is activated when a card is inserted. Convenient for Normally Closed (NC)
smart card connector.

CI/O
Input/
Output
This pin handles the connection to the serial I/O (C7) of the card connector. A
bidirectional level translator adapts the serial I/O signal between the card and the micro
controller. A 11 kW (typical) pull up resistor to CVCC provides a High impedance state for
the smart card I/O link.
