Smart Card Interface

APPLICATIONS

DESCRIPTION

•

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

General purpose smart card readers

The Teridian 73S8014RN is a single smart card (ICC) interface

circuit, firmware compatible with 8024-type devices for

configurations where only asynchronous cards must be

supported. It is derived from the 73S8024RN industry-

standard electrical interface. The 73S8014RN 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.

ADVANTAGES

•

NDS compliant

All NDS frequency divider rates of 4.5, 6.75 and

13.5MHz are supported from a 27MHz clock source

•

Same advantages as the Teridian 73S80xxR family:

The 73S8014RN interfaces with the host processor through the

same bus (digital I/Os) as the 73S8024RN, which is compatible

with any other 8024-type IC. As a result, the 73S8014RN is a

very attractive cost-reduction path from traditional 8024

ICs.

Card V_CCgenerated by an LDO regulator

Very low power dissipation (saves up to 1/2W)

Fewer external components are required

Better noise performance

•

True card over-current detection

Firmware compatibility with all 8024 ICs

Small format 20SO package

The 73S8014RN has been designed to provide full electrical

compliance with ISO 7816-3, EMV 4.0 and NDS specifications.

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.

FEATURES

•

Card Interface:

Complies with ISO 7816-3, EMV 4.0 and NDS

73S8014RN device supports 3V / 5V cards up to 65mA

ISO 7816-3 Activation / Deactivation sequencer

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

an external crystal or by connection to an externally supplied

clock signal. In addition, the clock divider provides divisor

values of divide by 1, 2, 4 and 6 that are compatible with NDS

requirements.

Automated deactivation upon hardware fault (i.e. upon

drop on V_DDpower supply or card overcurrent)

The 73S8014RN incorporates an ISO 7816-3

The V_DDvoltage supervisor threshold value (fault) can

be externally adjusted

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 powered

separately by a digital power supply V_DD. With its embedded

LDO regulator, the 73S8014RN is a cost-effective solution for

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

is available.

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

Emergency card deactivation is initiated upon card extraction

or upon any fault detected by the protection circuitry. The fault

can be a card over-current, V_CCundervoltage or power supply

fault (V_DD). The card over-current circuitry is a true current

detection function, as opposed to V_CCvoltage drop detection,

as usually implemented in non-Teridian 8024 interface ICs.

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: SO 20-pin

The V_DDvoltage fault has a threshold voltage that can be

adjusted with an external 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.

RoHS compliant (6/6) lead-free package
