APPLICATIONS  
•
Set-Top-Box Conditional Access and  
Pay-per-View  
DESCRIPTION  
•
SIM card readers in DECT and GSM phones,  
GPRS, WIFI and VOIP devices  
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.

General purpose smart card readers  
ADVANTAGES  
•
Lowest cost smart card interface IC on the  
market  
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.  
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  
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.  
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  
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.  
• 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  
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.  
• Over-current detection, 150 mA max.  
• 2 card detection inputs, 1 for each user  
polarity  
• Auxiliary I/O lines for C4 / C8 contact  
signals  
Auxiliary I/O lines are also available (SO28 package  
only) and make the 73S8009R suitable for all kind  
of cards, including synchronous (memory) cards.  
• Card CLK clock frequency up to 20 MHz
