73S8010R Low Cost Smart Card Interface Simplifying System Integration™ DATA SHEET DS_8010R_022 August 2009 APPLICATIONS • DESCRIPTION The Teridian 73S8010R is a single smart card interface IC that provides full electrical compliance with ISO-7816-3 and EMV 4.0 (EMV2000) specifications. Interfacing with the host is done through the two-wire 2 I C bus and one interrupt output to inform the system controller of the card presence and faults. The card clock signal can be generated by an on-chip oscillator using an external crystal, or by connection to a clock signal. The Teridian 73S8010R incorporates an ISO-7816-3 activation/deactivation sequencer that controls the card signals. Level-shifters drive the card signals with the selected card voltage (3 V or 5 V), coming from an internal Low Drop-Out (LDO) voltage regulator. This LDO regulator is powered by a dedicated power supply input, VPC. Digital circuitry is separately powered by a digital power supply, VDD. • • • ADVANTAGES • Single smart card interface • IC firmware compatible with TDA8020 • Traditional step-up converter is replaced by an LDO regulator  Greatly reduced power dissipation  Fewer external components are required  Better noise performance  High current capability (90 mA supplied to the card) • Small format (5x5x0.8 mm) QFN32 package option • True card over-current detection FEATURES • With its embedded LDO regulator, the Teridian 73S8010R is a cost-effective solution for any application where a 5 V (typically -5% +10%) power supply is available. Hardware support for auxiliary I/O lines, C4 / C8 contacts is provided. Emergency card deactivation is initiated upon card extraction or upon any fault generated by the protection circuitry. The fault can be a card over-current, a VDD (digital power supply), a VPC (regulator power supply), a VCC (card power supply) or an over-heating fault. The card over-current circuitry is a true current detect function, as opposed to VCC voltage drop detection, as usually implemented in ICC interface ICs. The VDD voltage fault has a threshold voltage that can be adjusted with an external resistor or resistor network. It allows automated card deactivation at a customized VDD voltage threshold value. It can be used, for instance, to match the system controller operating voltage range.

It is set low if any of the following internal faults are detected: • • • VCC fault VDD fault VPC fault The interrupt will also be set if one of the following status bit conditions is detected: • • • • Early ATR Mute ATR Card insert or card extract Protection status from Over-current or Over-heating When the interrupt is set low by the detection of one of the status bits, it is set high when the status bits are read. (READ STATUS DONE) Figure 10 shows the interrupt operation resulting from the fault or status bit conditions. INT ANY FAULT STATUS BITS READ STATUS DONE Figure 10: Interrupt operation due to Fault and Status Conditions A power-on-reset event will reset all of the control and status registers to their default states. A VDD fault event does not reset these registers, but it will signal an interrupt condition and by the action of the timer that creates the interval “t1,” not clearing the interrupt until VDD is valid for at least t1. A VDD fault can be considered valid for VDD as low as 1.5 to 1.8 volts. At the lower range of VDD fault, POR will be asserted. 20 Rev. 1.6 DS_8010R_022 73S8010R Data Sheet 3.10 Warm Reset 2 The 73S8010R automatically asserts a warm reset to the card when instructed through bit 1 of the I C Control register (bit Warm Reset). The warm reset length is automatically defined as 42,000 card clock cycles. The Warm Reset bit is automatically reset when the card starts answering or when the card is declared mute. IO Warm Reset (bit 1) RST t3 t2 t1 t1 > 1.5µs, Warm Reset Starts t2 = 42000 card clock cycles, End of Warm Reset t3 = Resets Warm Reset bit 1 when detected ATR or Mute Figure 11: Warm Reset Operation 3.11 I/O Circuitry and Timing The states of the I/O, AUX1, and AUX2 pins are low after power-on-reset and they are high when the activation sequencer enables the I/O reception state. See Section 3.7 Activation Sequence for more details on when the I/O reception is enabled. The states of the I/OUC, AUX1UC, and AUX2UC are high after power on reset. When the control I/O enable bit (bit 7) of the control register is set, the first I/O line on which a falling edge is detected becomes the input I/O line and the other becomes the output I/O line. When the input I/O line rising edge is detected, then both I/O lines return to their neutral state. The delay between these signals is shown in Figure 12.

This is done to insure consistency and follow the designations used in ISO 7816. Remove the MLP pin numbering in the pin description. Correct the clock division table under CARD CLOCK. Change the value of R2 on the typical application schematic. The original value is 100 KΩ and the updated value is 10 KΩ. The PRES input has a high impedance pull down resistor and the 100 KΩ for R2 is too high to insure a valid logic level on this input. 1.3 10/26/2005 Remove NDS references in application schematic. 1.5 1/21/2008 Removed leaded package option, replaced 32QFN punched with SAWN, updated 28SO dimension. Changed dimension of bottom exposed pad on 32QFN mechanical package figure. 1.6 8/28/2009 Added Section 6, Related Documentation and Section 7, Contact Information. Formatted to the corporate style.
