73S8009R Low Cost Versatile Smart Card Interface Simplifying System Integration DATA SHEET DS 8009R 056 October 2009 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 Point of Sales & Transaction Terminals level shifter interface between a 3.3 V (typical) logic General purpose smart card readers circuitry (host microcontroller) and an ISO-7816 / EMV smart card. The 73S8009R is designed to ADVANTAGES provide full electrical compliance with ISO-7816-3 Lowest cost smart card interface IC on the EMV4.1 (EMV2000) and GSM11-11 specifications. market In normal operating mode, for maximum designer Ideal to replace discrete designs in POS flexibility, the host microcontroller is responsible for terminals and Set-Top-Boxes card activation and deactivation. The 73S8009R Traditional step-up converter is replaced by incorporates an ISO-7816-3 deactivation sequencer an LDO regulator that controls the card signals in case of fault detection Greatly reduced power dissipation and card removal. Card presence and faults are reported to the host through an interrupt output. Fewer external components are required When the 73S8009R is ready to support a card with Better noise performance the selected voltage, a RDY signal informs the host it Very low power dissipation can initiate the card activation sequence. 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. FEATURES Level-shifters drive the card signals with the selected card voltage coming from an internal Low Drop-Out Card Interface: (LDO) voltage regulator. The LDO regulator is Complies with ISO-7816-3, EMV 4.0 and powered by a dedicated power supply input, VPC. GSM 11-11 specifications Digital circuitry is separately powered by a digital power supply, VDD. An LDO voltage regulator provides 1.8V / 3V / 5V to the card from an external power Emergency card deactivation is initiated upon card supply input extraction or any fault generated by the protection Provides at least 90 mA to the card circuitry. The fault can be a card over-current, a VDD ISO-7816-3 card emergency deactivation (digital power), a VPC (regulator power), a VCC sequencer (card power output) or an over-heating fault. Protection includes 3 voltage supervisors A chip select digital input drives internal latches that that detect voltage drops on V (card), V CC DD allow the host controller to control multiple (digital) and V (regulator) power supplies PC 73S8009R ICs in parallel. A power down digital Over-current detection, 150 mA max. input also allows the host microcontroller to place 2 card detection inputs, 1 for each user the IC in a very low-power mode making the polarity 73S8009R particularly suitable for low-power and battery-powered applications. Auxiliary I/O lines for C4 / C8 contact signals Auxiliary I/O lines are also available (SO28 package Card CLK clock frequency up to 20 MHz only) and make the 73S8009R suitable for all kind of cards, including synchronous (memory) cards.
