Smart Card Interface

Simplifying System Integration™

DATA SHEET

DESCRIPTION

FEATURES

The Teridian 73S8010C is a single smart card

interface IC. It provides full electrical compliance

with ISO-7816-3 and EMV 4.0 specifications.

•

Card Interface:

. Complies with ISO-7816-3 and EMV 4.0

. A DC-DC Converter provides 3V / 5V to the

card from an external power supply input

. High-efficiency converter: > 80% @ V_DD= 3.3 V,

V_CC= 5 V and I_CC= 65 mA

. Up to 100 mA supplied to the card

Interfacing with the host is done through the two-wire

I2C bus. Data exchange with the card is managed

from the system controller using the I/O line (and

eventually the auxiliary I/O lines).

. ISO-7816-3 Activation / Deactivation sequencer

with emergency automated deactivation on

card removal or fault detected by the protection

circuitry

. Protection include 2 voltage supervisors that

detect voltage drops on card V_CCand V_DD

power supplies

. The V_DDvoltage supervisor threshold value

can be externally adjusted

. True over-current detection (150 mA max.)

. 1 card detection input

An on-chip oscillator using an external crystal, or

connection to a clock signal coming from the

system controller can generate the card clock

signal.

The 73S8010C IC 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 DC-DC converter.

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

With its high-efficiency DC-DC converter, the

Teridian 73S8010C is a cost-effective solution for

any smart card reader application to be powered

from a single 2.7 V to 3.6 V power supply.

•

Host Interface:

. Fast mode, 400 kbps I²C slave bus

. 8 possible devices in parallel

. One control register and one status register

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

contacts, is provided.

. Interrupt output to the host for fault

detection

Emergency card deactivation is initiated upon card

extraction or upon any fault generated by the

protection circuitry. The fault can be a VDD (digital

power supply), a VCC (card power supply), a card

over-current, or an over-heating fault.

. Crystal oscillator or host clock, up to 27 MHz

Power Supply:

. V_DD: 2.7 V to 3.6 V

•

6 kV ESD Protection on the card interface

Package: SO28 or 32QFN

ADVANTAGES

•

Single smart card interface

The inductor-based DC-DC converter provides

higher current and efficiency than the usual

charge-pump capacitor-based converters

APPLICATIONS

•

Set-Top-Boxes, DVD / HDD Recorders:

Conditional Access and Pay-per-View slots

 Ideal for battery-powered applications

•

Point of Sales and Transaction Terminals

EMV slots in cell phones and PDAs

 Suitable for high current cards and

SAMs: (100 mA max)

•

Power down mode: 2 µA typical

Small Format (5x5mm) 32-QFN package option
