DESCRIPTION

The Teridian 73S8009C is a versatile power management and single smart card interface circuit that is ideally suited for smart card reader products that are battery and/or USB buspowered. In addition to its EMV 4.1 and ISO-7816-3 compliant smart card-to-host interface circuitry; it provides control, conversion, and regulation of power for a companion host processor circuit and power for the smart card.

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 VCC (card) and VDD (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

? Card CLK clock frequency up to 20 MHz

? 6 kV ESD and short circuit protection on

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) (Continue ...)

APPLICATIONS

? Handheld PINpad smart card readers for

e-commerce, secure login, e-health, Gov’t ID

and loyalty

? Point of Sales & Transaction Terminals

? General Purpose Smart Card Readers
