73S8014RT-IL/F集成电路（IC）的专用规格书PDF中文资料

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
