73S8009CN Combo ISO-7816 and USB Universal Smart Card Interface IC Simplifying System IntegrationTM DS_8009C_026 DATA SHEET August 2009 FEATURES DESCRIPTION The Teridian 73S8009CN is the world's first single-chip smart card electrical interface circuit that supports all types of smart cards: 5V, 3V and 1.8V, including traditional ISO-7816-3 asynchronous and synchronous type 1 and type 2, as well as USB, ISO-7816-12 cards. The 73S8009CN is ideally suited for applications such as desktop computers, laptops and general purpose smart card readers that require low power operation from a single 2.7V to 6.5V power supply voltage source. A power down mode ("OFF" mode) is available and exhibits a 10nA typical current consumption. The circuit provides control, conversion and regulation of power for the smart card. In addition, the circuit provides a 3.3V-regulated voltage that is used as an internal digital supply voltage to the host interface. It is also made available to supply power to some external circuitry (a host controller for instance). For asynchronous and synchronous smart card operation, the signals for RST, CLK, I/O and auxiliary signals AUX1 and AUX2 are directly controlled from the host processor and are level-shifted by the circuit to the selected VCC value. For more design flexibility, the host processor is responsible for handling the signal timing for smart card activation and deactivation under normal conditions. The power management circuitry allows operation from a single power supply source VPC (2.7V to 6.5V). VPC is converted using an inductive, step-up power converter to the intermediate voltage, VP. VP is used by linear voltage regulators and switches internal to the IC to create the voltages VDD and as required, VCC. VDD is used by the 73S8009CN and is also made available for the companion host processor circuit or for other external circuits. The 73S8009CN features an ON/OFF pin suitable to connect to a "push-on/push-off" main system switch. When the 73S8009CN is "OFF," the typical current drawn from VPC is 10nA. For applications that do not implement any ON/OFF system switch, the ON/OFF input pin can be driven from a digital output of the host processor. * Smart Card Interface: Smart card voltage VCC: o Selectable: 1.8V, 3V or 5V o Generated by an internal voltage regulator o Provides up to 65mA to 3V and 5V cards and up to 40mA to 1.8V cards ISO-7816-3 card emergency deactivation Voltage supervisor detects voltage drop on VCC (card supply) True card over-current detection 150mA max. 1 input for a card presence detection switch Auxiliary I/O lines for synchronous and ISO-7816-12 USB card support Proper isolation of smart card signals depending on smart card type Card CLK clock frequency up to 20MHz 6kV ESD and short circuit protection on the card interface System Controller Interface: Digital logic level: 3.3V 5 signal images of the card signals (RSTIN, CLKIN, I/OUC, AUX1UC and AUX2UC) 1 control signal to switch between synchronous / asynchronous and ISO-7816-12 USB smart card modes 2 inputs activate and select the card voltage (CMDVCC% and CMDVCC#) 2 outputs, interrupt to the system controller (OFF and RDY), to inform the system controller of the card presence / faults and status of the interface 1 Chip Select input 2 handshaking signals (OFF_REQ, OFF_ACK) for proper shutdown sequencing of all smart card signals ON/OFF Input for a Main System Switch DC-DC Step-up Converter: Generates an intermediary voltage VP Requires a single 10H Inductor (rated for 400mA maximum peak current) VDD power supply output available to power up external circuitry: 3.3V 0.3V, 40mA Industrial temperature range (-40 C to +85 C) Small format QFN32 package: 5x5mm RoHS compliant (6/6) lead-free package * * * * * * * Rev. 1.4 (c) 2009 Teridian Semiconductor Corporation 1 73S8009CN Data Sheet FUNCTIONAL DIAGRAM DS_8009CN_026 24K Debounce and Latch ON/OFF VPC 10uH ON 100K OFF_REQ 10F 0.1F LIN VP Linear/ DC -

The power supplied to VPC pin is converted to the voltage VP utilizing an inductive, step-up converter. A series power inductor (nominal value = 10H) is connected from pin VPC to pin LIN, and a 10F and a 0.1F filter capacitor must be connected to VPC. Note: When the VPC input voltage exceeds the nominal VP voltage (approximately 5.5V), the switching operation of the converter stops and the converter acts as a pass through for VPC to VP. Switching operation will automatically resume when VPC falls below the nominal VP voltage. VP requires a 4.7F filter capacitor and will have a nominal value of 5.5 volts during normal operation. VP is used by the smart card interface circuits (CLK, RST, I/O, AUX1, and AUX2) and is the source of the regulated smart card supply VCC. VCC can be selected for values of 5V, 3V, and 1.8V. The power supply output VDD is also produced from VP. VDD is used by the 73S8009CN circuit for logic, input / output buffering with the host. In addition, VDD can be used as a 3.3V regulated power supply for some external circuitry provided that no more than 40mA is needed (simultaneously to the 65mA current drawn from VCC). 3.3 Interface Function - ON/OFF Modes A power ON/OFF function is provided such that the circuit will be inoperative during the "OFF" state, consuming minimum current from VPC. Option 1: 73S8009CN supplies host/system power controlled by push button ON/OFF switch: Refer to Figure 3 for a typical electrical schematic when using an ON/OFF system switch. The ON/OFF pin shall be connected to an SPST switch to ground. If the circuit is OFF and the switch is closed for a de-bounce period of approximately 100ms, the circuit shall go into the "ON" state wherein all functions are operating in normal fashion. If the circuit is in the "ON" state and the ON/OFF pin is connected to ground for a period greater than the de-bounce period, OFF_REQ will be asserted high and held regardless of the state of ON/OFF. Typically, the OFF_REQ signal is presented to a host controller that will assert OFF_ACK high when it has completed all shutdown activities. When OFF_ACK is set high, the circuit will de-activate the smart card interface if required and turn off all analog functions and the VDD supply for the logic and companion circuits. The OFF_ACK pin is connected internally to OFF_REQ with a resistor such that if OFF_ACK is unconnected, the action of OFF_REQ will assert OFF_ACK high. In this configuration, the circuit shall go into the "OFF" state immediately if the interface is deactivated or immediately after deactivation if previously activated.. The default state upon application of power to VPC is the "OFF". Note that at any time, the controller may assert OFF_ACK and the 73S8009CN will go into the "OFF" state (regardless of activity on the ON/OFF main system switch). Option 2: ON/OFF status driven from the host processor (no system switch): Refer to Figure 4 for a typical electrical schematic when controlling the ON/OFF pin via host control. The ON/OFF pin can be connected to a host digital control signal to turn the 73S8009CN on or off. The host should monitor the VDD supply to determine when the switch debounce time has been achieved so the 73S8009CN can switch states (ON or OFF). When the 73S8009CN is OFF, the host should drive the ON/OFF pin low to initiate the turn ON process. The signal must remain low until the VDD supply voltage goes to 3.3V. The 73S8009CN is now ON and the ON/OFF pin should be driven back high. To turn off the 73S8009CN, the host should drive the ON/OFF signal low until the VDD supply goes to 0V. The 73S8009CN is now OFF and the ON/OFF pins should be driven back high. See Note 6. 16 Rev. 1.4 DS_8009CN_026 Important Notes: 73S8009CN Data Sheet 1. When the host is not powered by the VDD supply of the 73S8009CN, special care must be taken as the host signals going to the 73S8009CN can be active when the device is powered OFF. This can create issues such as excessive current drain on the control signals and potentially prohibit proper turn ON of the 73S8009CN. Series resistors on the input signals (except the ON/OFF input) are recommended to provide isolation and prevent any potential problems. The recommended value of these resistors is 47k. It is also necessary for the host to set these input signals to the low state (except for ON/OFF) when the 73S8009CN is OFF. False activation of the card is possible if the CMDVCC# or CMDVCC% inputs are low (with a card inserted) when the 73S8009CN is powered ON. For this reason, the proper sequencing of the 73S8009CN is required. The CMDVCC# or CMDVCC% inputs must be set high immediately before the ON/OFF input is taken low to turn on the 73S8009CN. The time between setting the CMDVCC# or CMDVCC% inputs high and the setting of the ON/OFF input set low should be kept to a minimum as the CMDVCC# or CMDVCC% inputs, when set high with the 73S8009CN OFF, will draw significant current under these conditions. The 47k series resistors will mitigate this current draw. However, some additional current will be drawn through the resistors to the CMDVCC# or CMDVCC% inputs during this time so it should be kept to a minimum. 2. For applications where ON/OFF is controlled by the host, the OFF_REQ and OFF_ACK signals do not need to be connected to the host. When the OFF_ACK pin is left unconnected, the 73S8009CN will turn off properly by the action of the internal resistor connection to OFF_REQ. 3. If the host is capable of selectively monitoring the I/O line, it can be used in place of the VDD supply monitor as it is tied to the VDD supply through a pull up resistor when the smart card interface is not activated. 4. When the 73S8009CN is powered OFF, the host will not be able to detect a card event (card insertion/removal). If this function is necessary, then the host must monitor the card connector switch separately. 5. For systems that do not use VDD to power the host controller, the host interface signals must operate at 3.3V as the 73S8009CN digital logic operates off the VDD (3.3V) supply regardless of the value of the VPC supply. 6. The ON/OFF pin is internally pulled up to VPC through a 24k resistor. Special care must be taken if the host signal controlling the ON/OFF signal is running at a voltage different from VPC. If this is the case, then either the host control signal must be a maximum VPC supply tolerant open drain output or an external circuit should provide some isolation between the host control signal and the ON/OFF pin. 7. For those systems that require low power operation or are battery operated, the host controller circuit firmware should place the 73S8009CN in the OFF state if no card activity is required. Rev. 1.4 17 73S8009CN Data Sheet DS_8009CN_026 3.4 System Controller Interface Five separate digital inputs and two outputs allow direct control of the card interface from the host: Pin CS: Chip select control. Pin CMDVCC# and/or CMDVCC%: When low, starts an activation sequence. Pin RSTIN: controls the card RST signal. Pin SC/USB: Routes AUXx signals to AUXxUC or USB Dx pins and provides proper tri-stating functionality. Pin RDY: Indicates when smart card power supply is stable and ready. Pin OFF: Indicator of card presence and any card fault conditions. Interrupt output to the host: When the card is not activated, the OFF pin informs the host about the card presence only (Low = No card in the reader, high = card inserted). When CMDVCC (#/% signals) is/are set low (card activation sequence requested from the host), low level on OFF means a fault has been detected (e.g. card removal during card session, or voltage fault, or thermal / over-current fault) that automatically initiates a deactivation sequence. The smart card pass through signals are enabled when the RDY conditions are met. 3.5 Card Power Supply and Voltage Supervision The 73S8009CN smart card interface IC incorporates an LDO voltage regulator for the card power supply, VCC (VP to VCC conversion uses an internal LDO). The voltage output is controlled by the digital input sequence of CMDVCC# and CMDVCC%. This regulator is able to provide either 1.8V, 3V or 5V card voltage sourced from the VP power supply. Internal digital circuitry is also powered by the VP power supply (except for the ON/OFF circuitry which is powered from VPC). A voltage supervisor checks the value of the voltage VCC. A card deactivation sequence is forced upon fault detected by voltage supervisor, overcurrent condition, or card removal event. The voltage regulator can provide a card current of 65mA in compliance with EMV 4.1 for 3-V and 5-V cards. The signals CMDVCC# and CMDVCC% control the turn-on, output voltage value, and turn-off of VCC. When either signal is asserted low, VCC will ramp to the selected value or if both signals are asserted low (within 400ns of each other), VCC will ramp to 1.8V. These signals are edge triggered. If CMDVCC% is asserted low (to command VCC to be 5V) and at a much later time (greater than 2s, typically), CMDVCC# is asserted low, it will be ignored (and vice versa.) At the assertion (low) of either or both CMDVCC (#/% signals), VCC will rise to the requested value. When VCC rises to an acceptable value, and stays above that value for approximately 20s, RDY will be set high. Approximately 510s after the fall of CMDVCC (#/%), the circuit will check the see if VCC is at or above the required minimum value (indicated by RDY=1) and if not, will begin an emergency deactivation sequence. During the 510s time, card removal, or de-assertion of CMDVCC (#/%) shall also initiate an emergency deactivation sequence. The circuit provides over-current protection and limits Icc to 150mA, maximum for self-protection. When an over-current condition is sensed, the circuit will invoke a deactivation sequence. 18 Rev. 1.4 DS_8009CN_026 73S8009CN Data Sheet 3.6 Activation and De-activation Sequence The host controller is fully responsible for the activation sequencing of the smart card signals CLK, RST, I/O, AUX1 and AUX2. All these signals are held low by the 73S8009CN when the card is in the deactivated state. Upon card activation (the fall of CMDVCC (#/%)), all the signals are held low by the 73S8009CN until RDY goes high. The host should set the signals RSTIN, I/OUC, CLKIN, AUX1UC and AUX2UC low prior to activating the card and allow RDY to go high before transitioning any of these signals. In order to initiate activation, the card must be present and OFF must be high. At t1 (500us), if RDY=0 or overcurrent, circuit will de-activate (safety feature) CMDVCC5 or CMDVCC3 VCC I/OUC I/O RDY RSTIN RST CLKIN CLK CLK=CLKIN if RDY=1 Ignored Ignored RST = RSTIN if RDY=1 Ignored I/O = I/OUC if RDY=1 t1 VCC valid I/O, AUX1, AUX2, CLK, RST are held LOW until RDY = 1 and CMDVCCx = 0 Figure 5: Activation Sequence Deactivation is initiated either by the system controller by setting both CMDVCC (#/%) high, or automatically in the event of hardware faults or assertion of the OFF_ACK signal. Hardware faults are over-current, under-voltage, and card extraction during the session. The host can manage the I/O signals, CLKIN, RSTIN, and CMDVCC (#/%) to create other de-activation sequences for non-emergency situations. The following steps show the deactivation sequence and the timing of the card control signals when the system controller sets the CMDVCC(x)B high: 1. 2. 3. 4. RST goes low at the end of time t1. De-assert CLK at the end of time t2. I/O goes low at the end of time t3. Exit reception mode. De-assert internal VCC_ON at the end of time t4. After a delay, VCC is de-asserted. Note: Since the 73S8009CN does not control the waveshape of CLK (it is determined by the input form the host CLKIN), there is no guarantee that the duty cycle of the last CLK high pulse will conform to duty cycle requirements during an emergency deactivation. Rev. 1.4 19 73S8009CN Data Sheet DS_8009CN_026 CMDVCC RST CLK I/O VCC_ON VCC t1 t2 t3 t4 t5 Figure 6: Deactivation Sequence 3.7 OFF and Fault Detection There are two different cases that the system controller can monitor the OFF signal: to query regarding the card presence outside card sessions, or for fault detection during card sessions. Outside a card session: In this condition, CMDVCC (#/%) are always high, OFF is low if the card is not present, and high if the card is present. Because it is outside a card session, no fault detection can occur and it will not act upon the OFF signal. No deactivation is required during this time. During a card session: CMDVCC# and/or CMDVCC% is always low, and OFF falls low if the card is extracted or if any fault detection is detected. At the same time that OFF is set low, the sequencer starts the deactivation process and the host should stop all transitions on the signal lines. Figure 4 shows the timing diagram for the signals CMDVCC (#/%), PRES, and OFF during a card session and outside the card session. OFF is low by card extracted PRES OFF CMDVCC VCC outside card session within card session OFF is low by any fault within card session Figure 7: OFF Activity 20 Rev. 1.4 DS_8009CN_026 73S8009CN Data Sheet 3.8 Chip Selection The CS pin allows multiple circuits to operate in parallel, driven from the same host control bus. When CS is high, the pins RSTIN, CMDVCC%, CMDVCC# and CLKIN control the chip as described. The pins I/OUC, AUX1UC, and AUX2UC have 11k pull-up resistors and operate to transfer data to the smart card via I/O, AUX1, and AUX2 when the smart card is activated. The signals OFF and RDY have 20k pull-up resistors. When CS goes low, the states of the pins RSTIN, CMDVCC%, CMDVCC, and CLKIN are latched and held internally. The pull-up for pins I/OUC, AUX1UC, and AUX2UC become a very weak pull-up of approximately 3 microamperes. No transfer of data is possible between I/OUC, AUX1UC, AUX2UC and the smart-card signals I/O, AUX1, and AUX2. The signals OFF and RDY are set to high impedance and the internal pull-up resistors of 20k are disconnected. With regard to de-activation, CS does not affect the operation of the fault sensing circuits and card sense input. CS does not affect the action of SC/USB. tDZ CS OFF, I/OUC, AUX1UC, AUX2UC tSL HI-Z STATE HI-Z STATE FUNCTIONAL CONTROL SIGNALS tIS tSI tID tDI Figure 8: CS Timing Definitions Rev. 1.4 21 73S8009CN Data Sheet DS_8009CN_026 3.9 I/O Circuitry and Timing The states of the I/O, AUX1, and AUX2 pins are low after power on reset and they are in high when the activation sequencer turns on the I/O reception state. See the Activation and De-activation Sequence section for more details on when the I/O reception is enabled. The states of I/OUC, AUX1UC, and AUX2UC are high after power on reset. Within a card session and when the I/O reception state is turned on, 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. Figure 6 shows the state diagram of how the I/O and I/OUC lines are managed to become input or output.
