DESCRIPTION
The Teridian 73S8014R is a single smart card (ICC) interface circuit, firmware compatible with 8024-type devices for configurations where only asynchronous cards must be supported. It is derived from the 73S8024RN industry standard electrical interface. The 73S8014R has been optimized to match most of the typical Set-Top-Box / A/V Conditional Access applications. Optimization essentially involved a smaller pin-count, support for single I/O, and maximum card current of 65mA (ISO-7816 / EMV compliance).
   
FEATURES
• Card Interface:
    ▪ Complies with ISO 7816-3 and EMV 4.0
    ▪ Supports 3V / 5V cards
    ▪ ISO 7816-3 Activation / Deactivation sequencer
    ▪ Automated deactivation upon hardware fault (i.e. upon
        drop on VDD power supply or card overcurrent)
    ▪ The VDD voltage supervisor threshold value (fault) can
        be externally adjusted
    ▪ Over-current detection 130mA max
    ▪ Card CLK clock frequency up to 20MHz
• System Controller Interface:
    ▪ 3 Digital inputs control the card activation /
        deactivation, card reset and card voltage
    ▪ 2 Digital inputs control the card clock frequency
    ▪ 1 Digital output, interrupt to the system controller,
        reports to the host the card presence and faults
    ▪ Crystal oscillator or host clock, up to 27MHz
• Regulator Power Supply:
    ▪ 4.75V to 5.5V
• Digital Interfacing: 2.7V to 5.5V
• 6kV ESD protection on the card interface
• Package: SO 20-pin
• RoHS compliant (6/6) lead-free package
   
APPLICATIONS
• Set-Top-Box Conditional Access and Pay-per-View
• General purpose smart card readers
