DESCRIPTION
The 73S8009R is a very low-cost level shifter, single smart card (ICC) interface IC. The device includes a level shifter interface between a 3.3 V (typical) logic circuitry (host microcontroller) and an ISO-7816 / EMV smart card. The 73S8009R is designed to provide full electrical compliance with ISO-7816-3 EMV4.1 (EMV2000) and GSM11-11 specifications.
   
FEATURES
• Card Interface:
    • Complies with ISO-7816-3, EMV 4.0 and
        GSM 11-11 specifications
    • An LDO voltage regulator provides 1.8V /
        3V / 5V to the card from an external power
        supply input
    • Provides at least 90 mA to the card
    • ISO-7816-3 card emergency deactivation
        sequencer
    • Protection includes 3 voltage supervisors
        that detect voltage drops on VCC (card), VDD
        (digital) and VPC (regulator) power supplies
    • Over-current detection, 150 mA max.
    • 2 card detection inputs, 1 for each user
        polarity
    • Auxiliary I/O lines for C4 / C8 contact
        signals
    • Card CLK clock frequency up to 20 MHz   
• System Controller Interface
    • Five signal images of the card signals
        (RSTIN, CLKIN, IOUC, AUX1UC, AUX2UC)
    • Two inputs select card voltage (CMDVCC%,
        CMDVCC#)
    • Two Interrupt outputs (OFF, RDY) inform the
        system controller of card presence / faults
        and the interface status
    • Chip select input (CS)
    • Power down input (PWRDN)
• Regulator Power Supply (VPC):
    • Class A-B-C readers: 5V, 3V and 1.8V
        cards: 4.75 V to 6.0 V
• Digital Interface (VDD): 2.7 V to 3.6 V
• 6 kV ESD protection on the card interface
• SO28 or QFN20 package
   
APPLICATIONS
• Set-Top-Box Conditional Access and
    Pay-per-View
• SIM card readers in DECT and GSM phones,
    GPRS, WIFI and VOIP devices
• Point of Sales & Transaction Terminals
• General purpose smart card readers
