DESCRIPTION

The 73S8009R is a very low-cost level shifter, single smart card (ICC) interface IC. The device includes a level shifter interface between a 3.3 V (typical) logic circuitry (host microcontroller) and an ISO-7816 / EMV smart card. The 73S8009R is designed to provide full electrical compliance with ISO-7816-3 EMV4.1 (EMV2000) and GSM11-11 specifications.

FEATURES

• Card Interface:

• Complies with ISO-7816-3, EMV 4.0 and

GSM 11-11 specifications

• An LDO voltage regulator provides 1.8V /

3V / 5V to the card from an external power

supply input

• Provides at least 90 mA to the card

• ISO-7816-3 card emergency deactivation

sequencer

• Protection includes 3 voltage supervisors

that detect voltage drops on VCC (card), VDD

(digital) and VPC (regulator) power supplies

• Over-current detection, 150 mA max.

• 2 card detection inputs, 1 for each user

polarity

• Auxiliary I/O lines for C4 / C8 contact

signals

• Card CLK clock frequency up to 20 MHz

• System Controller Interface

• Five signal images of the card signals

(RSTIN, CLKIN, IOUC, AUX1UC, AUX2UC)

• Two inputs select card voltage (CMDVCC%,

CMDVCC#)

• Two Interrupt outputs (OFF, RDY) inform the

system controller of card presence / faults

and the interface status

• Chip select input (CS)

• Power down input (PWRDN)

• Regulator Power Supply (VPC):

• Class A-B-C readers: 5V, 3V and 1.8V

cards: 4.75 V to 6.0 V

• Digital Interface (VDD): 2.7 V to 3.6 V

• 6 kV ESD protection on the card interface

• SO28 or QFN20 package

APPLICATIONS

• Set-Top-Box Conditional Access and

Pay-per-View

• SIM card readers in DECT and GSM phones,

GPRS, WIFI and VOIP devices

• Point of Sales & Transaction Terminals

• General purpose smart card readers
