DESCRIPTION

The Teridian 73S8024RN is a single smart card (ICC) interface IC that can be controlled by a dedicated control bus. The 73S8024RN has been designed to provide full electrical compliance with ISO-7816-3, EMV 4.0 (EMV2000) and NDS specifications.

FEATURES

• Card Interface:

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

▪ A LDO voltage regulator provides 3V / 5V to the card

from an external power supply input

▪ Provides at least 90mA to the card

▪ ISO-7816-3 Activation / Deactivation sequencer with

emergency automated deactivation on card removal

or fault detected by the protection circuitry

▪ Protection includes 3 voltage supervisors that detect

voltage drops on VCC (card), VDD (digital)**, and VPC

(regulator) power supplies

▪ The VDD voltage supervisor threshold value can be

externally adjusted**

▪ Over-current detection 150mA max

▪ Card clock stop high or low*

▪ 2 card detection inputs, 1 for each possible user

polarity

▪ Auxiliary I/O lines, for C4 / C8 contact signals*

▪ Card CLK clock frequency up to 20MHz

• System Controller Interface:

▪ 3 Digital inputs control the card activation /

deactivation, card reset and card voltage

▪ 4 Digital inputs control the card clock (division rate

and card clock stop modes)

▪ 1 Digital output, interrupt to the system controller,

allows the system controller to monitor 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: SO28, 20QFN or 32QFN

APPLICATIONS

• Set-Top-Box Conditional Access and Pay-per
