FEATURES
•
Smart card Interface:
•
Complies with ISO-7816-3 and EMV 4.1
and derivative standards
•
A DC-DC Converter provides 1.8 V/3 V/5 V
to the card from a wide range of external
power supply inputs
•
Provides up to 65 mA to the card
•
ISO-7816-3 Card emergency deactivation
sequencer
•
2 voltage supervisors detect voltage drops
on the V
CC
(card) and V
DD
(digital) power
supplies
•
Card over-current detection 150 mA max.
•
2 card detection inputs, 1 for either user
polarity
•
Auxiliary I/O lines for synchronous and
ISO-7816-12 USB card support

the card interface
•
System Controller Interface:
•
5 Signal images of the card signals
(RSTIN, CLKIN, I/OUC, AUX1UC and
AUX2UC)
•
2 Inputs activate and select the card
voltage (CMDVCC% and
CMDVCC#)
•
2 Outputs, interrupt to the system controller
(OFF and RDY), to inform the system
controller of the card presence / faults and
status of the interface
•
1 Chip Select input (CS - QFN32 only)
•
2 Handshaking signals for proper shutdown
sequencing of all output supply voltages
(OFF_REQ, OFF_ACK)
