Low Cost Versatile Smart Card
Interface
DATA SHEET
October 2009
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.
In normal operating mode, for maximum designer
flexibility, the host microcontroller is responsible for
card activation and deactivation. The 73S8009R
incorporates an ISO-7816-3 deactivation sequencer
that controls the card signals in case of fault detection
and card removal. Card presence and faults are
reported to the host through an interrupt output.
When the 73S8009R is ready to support a card with
the selected voltage, a RDY signal informs the host it
can initiate the card activation sequence.
The 73S8009R supports 5V, 3V and 1.8V cards.
Selection is done through 2 dedicated digital inputs.
Level-shifters drive the card signals with the selected
card voltage coming from an internal Low Drop-Out
(LDO) voltage regulator. The LDO regulator is
powered by a dedicated power supply input, VPC.
Digital circuitry is separately powered by a digital
power supply, VDD.
Emergency card deactivation is initiated upon card
extraction or any fault generated by the protection
circuitry. The fault can be a card over-current, a VDD
(digital power), a VPC (regulator power), a VCC
(card power output) or an over-heating fault.
A chip select digital input drives internal latches that
allow the host controller to control multiple
73S8009R ICs in parallel. A power down digital
input also allows the host microcontroller to place
the IC in a very low-power mode making the
73S8009R particularly suitable for low-power and
battery-powered applications.
Auxiliary I/O lines are also available (SO28 package
only) and make the 73S8009R suitable for all kind
of cards, including synchronous (memory) cards.
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
ADVANTAGES
• Lowest cost smart card interface IC on the
market
Ideal to replace discrete designs in POS
terminals and Set-Top-Boxes
• Traditional step-up converter is replaced by
an LDO regulator
Greatly reduced power dissipation
Fewer external components are required
Better noise performance
Very low power dissipation
• Small format (4x4x0.8 mm) QFN20 package
option
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
