DESCRIPTION
The Teridian 73S8014RT is a single smart card (ICC) interface circuit. It is derived from the 73S8024RN industry-standard electrical interface but adds support for 1.8V smart card applications. The 73S8014RT 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
▪ 73S801RT device supports 3V / 5V cards up to
65mA and 1.8V up to 40mA
▪ 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)
• 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-perView
• General purpose smart card readers
