FEATURES
Smart card Interface:
Complies with ISO-7816-3 and EMV 4.1
and derivative standards
A DC-DC Converter provides 1.8V/3V/5V to
the card from a wide range of external
power supply inputs
Provides up to 65mA to the card
ISO-7816-3 Card emergency deactivation
sequencer
2 voltage supervisors detect voltage drops
on the VCC (card) and VDD (digital) power
supplies
Card over-current detection 150mA max.
2 card detection inputs, 1 for either user
polarity
Auxiliary I/O lines for synchronous and
ISO-7816-12 USB card support
Card CLK clock frequency up to 20MHz
6kV ESD and short circuit protection on the
card interface
System Controller Interface:
5 Signal images of the card signals
(RSTIN, CLKIN, IOUC, 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)
ON/OFF Main System Switch:
Input for an SPST momentary switch to
ground
DC-DC Converter:
Step-up converter
Generates an intermediary voltage V
P
Requires a single 10H Inductor
System Power Supply requirements:
When using VBUS: Standard USB +5V
input (range +4.4V to 5.5V)
When using V
BAT: 4.0V to 6.5V
When using V
PC: 2.7V to 6.5V
Automated detection of voltage presence -
Priority on VBUS over VBAT
Power Supply Output:
V
DD supply output available to power up
external circuitry: 3.3V
±0.3V, 40mA
Industrial temperature range
Small format QFN20 and QFN packages
RoHS compliant (6/6) lead-free package
