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
