73S8010R Low Cost Smart Card Interface Simplifying System Integration DATA SHEET DS 8010R 022 August 2009 APPLICATIONS Set-Top-Box Conditional Access and Pay-per-View Point of Sales & Transaction Terminals DESCRIPTION Control Access & Identification The Teridian 73S8010R is a single smart card Multiple card and SAM reader configurations interface IC that provides full electrical compliance with ISO-7816-3 and EMV 4.0 (EMV2000) ADVANTAGES specifications. Single smart card interface IC firmware compatible with TDA8020 Interfacing with the host is done through the two-wire 2 Traditional step-up converter is replaced by I C bus and one interrupt output to inform the system controller of the card presence and faults. an LDO regulator The card clock signal can be generated by an Greatly reduced power dissipation on-chip oscillator using an external crystal, or by Fewer external components are required connection to a clock signal. Better noise performance High current capability (90 mA supplied to The Teridian 73S8010R incorporates an ISO-7816-3 the card) activation/deactivation sequencer that controls the Small format (5x5x0.8 mm) QFN32 package option card signals. Level-shifters drive the card signals with True card over-current detection the selected card voltage (3 V or 5 V), coming from an internal Low Drop-Out (LDO) voltage regulator. This FEATURES LDO regulator is powered by a dedicated power . Digital circuitry is separately Card Interface supply input, V PC powered by a digital power supply, V . DD Complies with ISO-7816-3 and EMV 4.0 An LDO voltage regulator provides 3 V / 5 V to With its embedded LDO regulator, the Teridian the card from an external power supply input 73S8010R is a cost-effective solution for any ISO-7816-3 Activation / Deactivation application where a 5 V (typically -5% +10%) power sequencer with emergency automated supply is available. Hardware support for auxiliary deactivation on card removal or fault I/O lines, C4 / C8 contacts is provided. detected by the protection circuitry Protection includes 3 voltage supervisors Emergency card deactivation is initiated upon that detect voltage drops on V card and card extraction or upon any fault generated by CC on power supplies V and V the protection circuitry. The fault can be a card DD PC over-current, a V (digital power supply), a V Over-current detection 150 mA max DD PC (regulator power supply), a V (card power supply) CC 1 card detection input or an over-heating fault. Auxiliary I/O lines, for C4 / C8 contact signals The card over-current circuitry is a true current detect Host Interface function, as opposed to V voltage drop detection, as CC 2 Fast mode, 400 kbps I C slave bus usually implemented in ICC interface ICs. 8 possible devices in parallel The V voltage fault has a threshold voltage that DD One control register and one status can be adjusted with an external resistor or resistor register network. It allows automated card deactivation at a Interrupt output to the host for fault customized V voltage threshold value. It can be DD detection used, for instance, to match the system controller Crystal oscillator or host clock, up to 27 MHz operating voltage range. 6 kV ESD protection on the card interface SO28 or QFN32 package Rev. 1.6 2009 Teridian Semiconductor Corporation 1 73S8010R Data Sheet DS 8010R 022 FUNCTIONAL DIAGRAM VDD VDDF ADJ GND VPC 20 21 17 18 2 5 3 6 4, 5, 6, 9, 16, 25, 32 7, 8, 9 NC VPC FAULT 1 4 21 22 VDD FAULT VDD VOLTAGE SUPERVISOR GND GND LDO VOLTAGE REFERENCE REGULATOR VCC FAULT 12 14 & GND VOLTAGE SUPERVISORS 18 19 15 17 SCL Int Clk R-C VCC 19 20 OSC.
