73S8024RN

Low Cost Smart Card Interface

DATA SHEET

January 2009

DESCRIPTION

ADVANTAGES

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.

•

Traditional step-up converter is replaced by a LDO

regulator:

Æ Greatly reduced power dissipation

Æ Fewer external components are required

Æ Better noise performance

Interfacing with the system controller is done through a

control bus, composed of digital inputs to control the

interface, and one interrupt output to inform the system

controller of the card presence and faults.

Æ High current capability (90mA supplied to the card)

•

SO28 package is pin-to-pin compatible with

industry-standard TDA8004 and TDA8024

•

Card clock STOP (high and low) mode

Small format (4x4x0.85mm) 20QFN package option

True card over-current detection

The card clock can be generated by an on-chip oscillator

using an external crystal or by connection to a clock

signal.

FEATURES

The 73S8024RN incorporates an ISO-7816-3

activation/deactivation sequencer that controls the card

signals. Level-shifters drive the card signals with the

selected card voltage (3V or 5V), coming from an internal

Low Drop-Out (LDO) voltage regulator. This LDO

regulator is powered by a dedicated power supply input

V_PC. Digital circuitry is separately powered by a digital

•

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

power supply V_DD

ISO-7816-3 Activation / Deactivation sequencer with

emergency automated deactivation on card removal

or fault detected by the protection circuitry

With its embedded LDO regulator, the 73S8024RN is a

cost effective solution for any application where a 5V

(typically -5% +10%) power supply is available.

Hardware support for auxiliary I/O lines, C4 / C8 contacts,

is provided*.

Protection includes 3 voltage supervisors that detect

voltage drops on V_CC(card), V_DD(digital)**, and V_PC

(regulator) power supplies

The V_DDvoltage supervisor threshold value can be

externally adjusted**

Emergency card deactivation is initiated upon card

extraction or upon any fault generated by the protection

circuitry. The fault can be a card over-current, a V_DD

(digital power supply)**, a V_PC(regulator power supply), a

V_CC(card power supply) or an over-heating fault.

Over-current detection 150mA max

Card clock stop high or low*

2 card detection inputs, 1 for each possible user

polarity

The card over-current circuitry is a true current detection

function, as opposed to V_CCvoltage drop detection, as

usually implemented in ICC interface ICs.

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

Card CLK clock frequency up to 20MHz

•

System Controller Interface:

The V_DDvoltage fault has a threshold voltage that can be

adjusted with an external resistor or resistor network. It

allows automated card deactivation at a customized V_DD

voltage threshold value. It can be used, for instance, to

match the system controller operating voltage range.

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.

APPLICATIONS

•

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

View

Crystal oscillator or host clock, up to 27MHz

•

Point of Sales and Transaction Terminals

Control Access and Identification

•

Regulator Power Supply:

4.75V to 5.5V (EMV 4.0)

4.85V to 5.5V (NDS)

* Pins/functions not available on 20-pin QFN package.

** User V_{DD_FLT}threshold configuration not available on

20-pin QFN package.

•

Digital Interfacing: 2.7V to 5.5V

6kV ESD Protection on the card interface

Package: SO28, 20QFN or 32QFN
