73S8010R

Low Cost Smart Card Interface

Simplifying System Integration™

DATA SHEET

DS_8010R_022

APPLICATIONS

•

Set-Top-Box Conditional Access and

Pay-per-View

•

Point of Sales & Transaction Terminals

Control Access & Identification

Multiple card and SAM reader configurations

DESCRIPTION

The Teridian 73S8010R is a single smart card

interface IC that provides full electrical compliance

with ISO-7816-3 and EMV 4.0 (EMV2000)

specifications.

ADVANTAGES

•

Single smart card interface

IC firmware compatible with TDA8020

Traditional step-up converter is replaced by

an LDO regulator

 Greatly reduced power dissipation

 Fewer external components are required

 Better noise performance

Interfacing with the host is done through the two-wire

I²C bus and one interrupt output to inform the

system controller of the card presence and faults.

The card clock signal can be generated by an

on-chip oscillator using an external crystal, or by

connection to a clock signal.

 High current capability (90 mA supplied to

the card)

Small format (5x5x0.8 mm) QFN32 package option

The Teridian 73S8010R incorporates an ISO-7816-3

activation/deactivation sequencer that controls the

card signals. Level-shifters drive the card signals with

the selected card voltage (3 V or 5 V), 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

•

True card over-current detection

FEATURES

• Card Interface

• Complies with ISO-7816-3 and EMV 4.0

• An LDO voltage regulator provides 3 V / 5 V to

the card from an external power supply input

• ISO-7816-3 Activation / Deactivation

sequencer with emergency automated

deactivation on card removal or fault

With its embedded LDO regulator, the Teridian

73S8010R is a cost-effective solution for any

application where a 5 V (typically -5% +10%) power

supply is available. Hardware support for auxiliary

I/O lines, C4 / C8 contacts is provided.

detected by the protection circuitry

• Protection includes 3 voltage supervisors

that detect voltage drops on V_CCcard and

on power supplies V_DDand V_PC

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 150 mA max

• 1 card detection input

• Auxiliary I/O lines, for C4 / C8 contact

signals

The card over-current circuitry is a true current detect

function, as opposed to V_CCvoltage drop detection, as

usually implemented in ICC interface ICs.

•

Host Interface

•

Fast mode, 400 kbps I²C slave bus

8 possible devices in parallel

One control register and one status

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_DDvoltage threshold value. It can be

used, for instance, to match the system controller

operating voltage range.

•

Interrupt output to the host for fault

detection

•

Crystal oscillator or host clock, up to 27 MHz

•

6 kV ESD protection on the card interface

SO28 or QFN32 package
