DESCRIPTION

The Teridian 73S8014RN 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 73S8014RN has been optimized to match most of the typical Set-Top Box / A/V Conditional Access applications. Optimization essentially involved a smaller pin-count and support for single I/O.

FEATURES

• Card Interface:

▪ Complies with ISO 7816-3, EMV 4.0 and NDS

▪ 73S8014RN device supports 3V / 5V cards up to 65mA

▪ 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 (EMV 4.0)

▪ 4.85V to 5.5V (NDS)

• 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
