73S8010C Smart Card Interface Simplifying System Integration DATA SHEET April 2009 DESCRIPTION FEATURES The Teridian 73S8010C is a single smart card Card Interface: interface IC. It provides full electrical compliance Complies with ISO-7816-3 and EMV 4.0 with ISO-7816-3 and EMV 4.0 specifications. A DC-DC Converter provides 3V / 5V to the card from an external power supply input Interfacing with the host is done through the two-wire High-efficiency converter: > 80% V = 3.3 V, DD I2C bus. Data exchange with the card is managed V = 5 V and I = 65 mA CC CC from the system controller using the I/O line (and Up to 100 mA supplied to the card eventually the auxiliary I/O lines). ISO-7816-3 Activation / Deactivation sequencer with emergency automated deactivation on An on-chip oscillator using an external crystal, or card removal or fault detected by the protection connection to a clock signal coming from the circuitry system controller can generate the card clock signal. Protection include 2 voltage supervisors that detect voltage drops on card V and V CC DD The 73S8010C IC incorporates an ISO-7816-3 power supplies activation/deactivation sequencer that controls the The V voltage supervisor threshold value DD card signals. Level shifters drive the card signals can be externally adjusted with the selected card voltage (3 V or 5 V), coming True over-current detection (150 mA max.) from an internal DC-DC converter. 1 card detection input Auxiliary I/O lines, for C4 / C8 contact signals With its high-efficiency DC-DC converter, the Teridian 73S8010C is a cost-effective solution for Host Interface: any smart card reader application to be powered 2 from a single 2.7 V to 3.6 V power supply. Fast mode, 400 kbps I C slave bus 8 possible devices in parallel Hardware support for auxiliary I/O lines, C4 / C8 One control register and one status register contacts, is provided. Interrupt output to the host for fault detection Emergency card deactivation is initiated upon card Crystal oscillator or host clock, up to 27 MHz extraction or upon any fault generated by the protection circuitry. The fault can be a VDD (digital Power Supply: power supply), a VCC (card power supply), a card over-current, or an over-heating fault. V : 2.7 V to 3.6 V DD 6 kV ESD Protection on the card interface ADVANTAGES Package: SO28 or 32QFN Single smart card interface The inductor-based DC-DC converter provides APPLICATIONS higher current and efficiency than the usual charge-pump capacitor-based converters Set-Top-Boxes, DVD / HDD Recorders: Conditional Access and Pay-per-View slots Ideal for battery-powered applications Point of Sales and Transaction Terminals Suitable for high current cards and SAMs: (100 mA max) EMV slots in cell phones and PDAs Power down mode: 2 A typical Small Format (5x5mm) 32-QFN package option Rev. 1.5 2009 Teridian Semiconductor Corporation 1 73S8010C Data Sheet DS 8010C 024 FUNCTIONAL DIAGRAM Figure 1: 73S8010C Block Diagram Pin number reference to SO28 Package Pin number reference to 32QFN Package 2 Rev. 1.5
