The supply pins are VDDD, DGND and AGND. Pins VDDA and AGND supply the analog drivers to the card and have to be externally decoupled because of the large current spikes that the card and the step-up converter can create. An integrated spike killer ensures the contacts to the card remain inactive during power-up or power-down. An internal voltage reference is generated which is used within the step-up converter, the voltage supervisor, and the VCC generator. The microcontroller is an 80CL51 with 256 bytes of RAM instead of 128. The baud rate of the UART has been multiplied by four in modes 1, 2 and 3 (which means that the division factor of 32 in the formula is replaced by 8 in both reception and transmission, and that in the reception modes, only four samples per bit are taken with decision on the majority of samples 2, 3 and 4) and the delay counter has been reduced from 1536 to 24. Remark: this has an impact when getting out of PDOWN mode. It is recommended to switch to internal clock before entering PDOWN mode (see "application report"). The voltage supervisor generates an alarm pulse, whose length is defined by an external capacitor tied to the DELAY pin, when VDDD is too low to ensure proper operation (1 ms per 1 nF typical). This pulse is used as a RESET pulse by the controller, in parallel with an external RESET input, which can be tied to the system controller. All the other functions remain unchanged. Please, refer to the published specification of the 80CL51 for any further information. Pins INT0, P10, P04 to P07 and P24 to P27 are used internally for controlling the smart card interface. It is also used in order to either block any spurious card contacts during controllers reset, or to force an automatic deactivation of the contacts in the event of supply drop-out [see Sections "Activation sequence" and "Deactivation sequence (see Fig.10)"]. Mode 0 is unchanged. The baud rate for modes 1 and 3 is: SMOD f clk 2 ------------------ x -------------------------------------------------8 12 x ( 256 - TH1 ) In the 64 pin version, this reset pulse is output to the open drain ALARM pin, which may be selected active HIGH or active LOW by mask option and may be used as a reset pulse for other devices within the application. SMOD 2 The baud rate for mode 2 is: ------------------ x f clk 16 Table 1 Mode 3 timing BAUD RATE fclk = 6.5 MHz; VDD = 5 V fclk = 3.25 MHz; VDD = 5 or 3 V SMOD TH1 135416 1 255 - - 67708 0 255 1 255 45139 1 253 - - 33854 0 254 0 255 27083 1 251 - - 22569 0 253 1 253 16927 - - 0 254 13542 - - 1 251 11285 0 250 0 253 1996 Sep 25 SMOD TH1 9 Philips Semiconductors Product specification Low-power smart card coupler handbook, full pagewidth TDA8005 Vth1 + Vhys1 Vth1 V DD Vth2 VDEL ALARM MBH634 Fig.4 Supply supervisor. chosen as a doubler or a tripler by mask option, depending on the voltage and the current needed on the card. Low impedance supply (pin LIS) For some applications, it is mandatory that the contacts to the card (VCC, RST, CLK and I/O) are low impedance while the card is inactive and also when the coupler is not powered. An auxiliary supply voltage on pin LIS ensures this condition where ILIS = <5 A for VLIS = 5 V. This low impedance situation is disabled when VCC starts rising during activation, and re-enabled when the step-up converter is stopped during deactivation. If this feature is not required, the LIS pin must be tied to VDD. ISO 7816 security The correct sequence during activation and deactivation of the card is ensured through a specific sequencer, clocked by a division ratio of the internal oscillator. Activation (START signal P05) is only possible if the card is present (PRES HIGH or LOW according to mask option), and if the supply voltage is correct (ALARM signal inactive), CLK and RST are controlled by RSTIN (P04), allowing the correct count of CLK pulses during Answer-to-Reset from the card. Step-up converter Except for the VCC generator, and the other cards contacts buffers, the whole circuit is powered by VDDD and VDDA. If the supply voltage is 3 V or 5 V, then a higher voltage is needed for the ISO contacts supply. When a card session is requested by the controller, the sequencer first starts the step-up converter, which is a switched capacitors type, clocked by an internal oscillator at a frequency approximately 2.5 MHz. The output voltage, VUP, is regulated at approximately 6,5 V and then fed to the VCC generator. VCC and GND are used as a reference for all other cards contacts. The step-up converter may be 1996 Sep 25 The presence of the card is signalled to the controller by the OFF signal (P10). During a session, the sequencer performs an automatic emergency deactivation in the event of card take-off, supply voltage drop, or hardware problems. The OFF signal falls thereby warning the controller. 10 Philips Semiconductors Product specification Low-power smart card coupler TDA8005 active. The card is not active; this is the smallest power consumption mode. Any change on P1 ports or on PRES will wake-up the circuit (for example, a key pressed on the keyboard, the card inserted or taken off). Clock circuitry The clock to the microcontroller and the clock to the card are derived from the main clock signal (XTAL from 2 to 16 MHz, or an external clock signal). In the sleep mode, the card is powered, but configured in the Idle or sleep mode. The step-up converter will only be active when it is necessary to reactivate VUP. When the microcontroller is in Power-down mode any change on P1 ports or on PRES will wake up the circuit. Microcontroller clock (fclk) after reset, and during power reduction modes, the microcontroller is clocked with fINT/8, which is always present because it is derived from the internal oscillator and gives the lowest power consumption. When required, (for card session, serial communication or anything else) the microcontroller may choose to clock itself with 12fxtal, 14fxtal or 12fINT. All frequency changes are synchronous, thereby ensuring no hang-up due to short spikes etc. In both power reduction modes the sequencer is active, allowing automatic emergency deactivation in the event of card take-off, hardware problems, or supply drop-out. The TDA8005 is set into Power-down or sleep mode by software. There are several ways to return to normal mode, Introduction or extraction of the card, detection of a change on P1 (which can be a key pressed) or a command from the system microcontroller. For example, if the system monitors the clock on XTAL1, it may stop this clock after setting the device into power-down mode and then wake it up when sending the clock again. In this situation, the internal clock should have been chosen before the fclk. Cards clock: the microcontroller may select to send the card 12fxtal, 14fxtal, 18fxtal or 12fINT (1.25 MHz), or to stop the clock HIGH or LOW. All transition are synchronous, ensuring correct pulse length during start or change in accordance with ISO 7816. After power on, CLK is set at STOP LOW, and fclk is set at 1 f 8 INT. Power-down and sleep modes Peripheral interface The TDA8005 offers a large flexibility for defining power reduction modes by software. Some configurations are described below. This block allows synchronous serial communication with the three peripherals (ISO UART, CLOCK CIRCUITRY and OUTPUT PORTS EXTENSION).

ISO UART The ISO UART handles all the specific requirements defined in ISO T = 0 protocol type. It is clocked with the cards clock, which gives the fclk/31 sampling rate for start bit detection (the start bit is detected at the first LOW level on I/O) and the fclk/372 frequency for ETU timing (in the reception mode the bit is sampled at 12ETU). It also allows the cards clock frequency changes without interfering with the baud rate. After power-on, all ISO UART registers are reset. The ISO UART is configured in the reception mode. When the microcontroller wants to start a session, it sets the bits START SESSION and RESET ISO UART in UART CONFIGURATION and then sets START LOW. When the first start bit on I/O is detected (sampling rate fclk/31), the UART sets the bit US2 (First Start Detect) in the status register which gives an interrupt on INT0 one CLK pulse later. This hardware UART allows operating of the microcontroller at low frequency, thus lowering EM radiations and power consumption. It also frees the microcontroller of fastidious conversions and real time jobs thereby allowing the control of higher level tasks. The convention is recognized on the first character of the ATR and the UART configures itself in order to exchange direct data without parity processing with the microcontroller whatever the convention of the card is. The bit START SESSION must be reset by software. At the end of every character, the UART tests the parity and resets what is necessary for receiving another character. The following occurs in the reception mode (see Fig.6): * Detection of the inverse or direct convention at the begin of ATR. * Automatic convention setting, so the microcontroller only receives characters in direct convention. If no parity error is detected, the UART sets the bit US1 (BUFFER FULL) in the STATUS REGISTER which warns the microcontroller it has to read the character before the reception of the next one has been completed. The STATUS REGISTER is reset when read from the controller. * Parity checking and automatic request for character repetition in case of error (reception is possible at 12 ETU). In the transmission mode (see Fig.7): * Transmission according to the convention detected during ATR, consequently the microcontroller only has to send characters in direct convention. Transmission of the next character may start at 12 ETU in the event of no error or 13 ETU in case of error. If a parity error has been detected, the UART pulls the I/O line LOW between 10.5 and 12 ETU. It also sets the bits BUFFER FULL and US3 (parity error during reception) in the STATUS REGISTER which warns the microcontroller that an error has occurred. The card is supposed to repeat the previous character. * Parity calculation and detection of repetition request from the card in the event of error. * The bit LCT (Last Character to Transmit) allows fast reconfiguration for receiving the answer 12 ETU after the start bit of the last transmitted character. The ISO UART status register can inform which event has caused an interrupt. (Buffer full, buffer empty, parity error detected etc.) cf Peripheral Interface. This register is reset when the microcontroller reads the status out of it. 1996 Sep 25 14 Philips Semiconductors Product specification Low-power smart card coupler handbook, full pagewidth T/R = 0 or LCT = 1 TDA8005 start session and T/R = 0 SET ENABLE FSD clock starts INHIBIT I/O DURING 200 CLK SAMPLE I/O EVERY 31 CLK I/O = 0 SET FSD STATUS REGISTER IN FSD IS ENABLED RESET EN FSD 5th bit SAMPLE I/O AT 186 AND EVERY 372 CLK SET CONVENTION IF START SESSION = 1 (1) 10th bit CONVERT AND LOAD CHARACTER IN RECEPTION BUFFER AT 10 ETU parity error CHECK PARITY SET BIT RECEPTION PARITY ERROR AT 10 ETU DISABLE I/O BUFFER BETWEEN 10 AND 12 ETU PULL I/O LINE LOW FROM 10.5 TILL 11.75 ETU SET BIT BUFFER FULL AT 10 ETU RESET RECEPTION PART AT 12 ETU (2) MBH636 T/R =1 (1) The start session is reset by software. (2) The software may load the received character in the peripheral control at any time without any action on the ISO UART. Fig.6 ISO UART reception flow chart. When the controller needs to transmit data to the card, it first sets the bit UC3 in the UART CONFIGURATION which configures the UART in the transmission mode. As soon as a character has been written in the UART TRANSMIT register, the UART makes the conversion, 1996 Sep 25 calculates the parity and starts the transmission on the rising edge of ENABLE. When the character has been transmitted, it surveys the I/O line at 11 ETU in order to know if an error has been detected by the card. 15 Philips Semiconductors Product specification Low-power smart card coupler TDA8005 If no error has occurred, the UART sets the bit US0 (BUFFER EMPTY) in the STATUS REGISTER and waits for the next character. If the next character has been written before 12 ETU, the transmission will start at 12 ETU. If it was written after 12 ETU it will start on the rising edge of ENABLE. 13 ETU. If it has been written after 13 ETU it will start on the rising edge of ENABLE. When the transmission is completed, the microcontroller may set the bit LCT (Last Character to Transmit) so that the UART will force the reception mode into ready to get the reply from the card at 12 ETU. This bit must be reset before the end of the first reception. The bit T/R must be reset to enable the reception of the following characters. If an error has occurred, it sets the bits BUFFER EMPTY and US4 (parity error during transmission) which warns the microcontroller to rewrite the previous character in the UART TRANSMIT register. If the character has been rewritten before 13 ETU, the transmission will start at When the session is completed, the microcontroller re-initializes the whole UART by resetting the bit RESET ISO UART.

Beyond this window, RSTIN has no more action on clock, and only monitors the cards RST contact (RST is the inverse of RSTIN). I/O buffer modes (see Fig.8) The following are the I/O buffer modes: 1.

I/O buffer in input, 20 k pull-up resister connected between I/O and VCC, I/O is sampled every 31 clock pulses. The sequencer is clocked by fINT/64 which leads to a time interval T of 25 s typical. Thus t1 = 0 to 164T, t2 = t1 + 123T, t3 = t1 + 4T, t4 = t3 to t5 and t5 = t1 + 7T (see Fig.9). 4. I/O buffer in output, 20 k pull-up resister connected between I/O and VCC. Deactivation sequence (see Fig.10) 5. I/O buffer in output, I/O is pulled LOW by the N transistor of the buffer. When the session is completed, the microcontroller sets START HIGH. The circuit then executes an automatic deactivation sequence: 6. I/O buffer in output, I/O is strongly HIGH or LOW by the P or N transistor. * Card reset (RST falls LOW) at t10 Output ports extension * Clock is stopped at t11 In the LQFP64 version, 6 auxiliary output ports may be used for low frequency tasks (for example, keyboard scanning). These ports are push-pull output types (cf use in software document). * I/O becomes high impedance to the ISO UART (t12) * VCC falls to 0 V with typical 0.1 V/s slew rate (t13) * The step-up converter is stopped and CLK, RST, VCC and I/O become low impedance to GND (t14). * t10 < 164T; t11 = t10 + 12T; t12 = t10 + T; t13 = t10 + 123T; t14 = t10 + 5T. Activation sequence When the card is inactive, VCC, CLK, RST and I/O are LOW, with low impedance with respect to GND. The step-up converter is stopped. The I/O is configured in the reception mode with a high impedance path to the ISO UART, subsequently no spurious pulse from the card during power-up will be taken into account until I/O is enabled. When everything is satisfactory (voltage supply, card present, no hardware problems), the microcontroller may initiate an activation sequence by setting START LOW (t0): Protections Main hardware fault conditions are monitored by the circuit * Overcurrent on VCC * Short circuits between VCC and other contacts * Card take-off during transaction. When one of these problems is detected, the security logic block pulls the interrupt line OFF LOW, in order to warn the microcontroller, and initiates an automatic deactivation of the contacts. When the deactivation has been completed, the OFF line returns HIGH, except if the problem was due to a card extraction in which case it remains LOW till a card is inserted. * The step-up converter is started (t1) * LIS signal is disabled by ENLI, and VCC starts rising from 0 to 5 V with a controlled rise time of 0.1 V/s typically (t2) * I/O buffer is enabled (t3) * Clock is sent to the card (t4) * RST buffer is enabled (t5). 1996 Sep 25 17 Philips Semiconductors Product specification Low-power smart card coupler handbook, full pagewidth activation character reception with error TDA8005 character transmission with error character reception without error character transmission without error forced deactivation character reception without error I/O OUT I/O BUFFER IN T ISO UART MODE R 1 2 3 4 54 3 4 1 6 3 6 3 3 4 3 1 MBH638 Fig.8 I/O buffer modes. tact handbook, full pagewidth PRES OFF START fINT/64 VUP VCC I/O ENRST internal RSTIN CLK RST ENLI internal MBH639 t3 t5 Fig.9 Activation sequence. 1996 Sep 25 18 Philips Semiconductors Product specification Low-power smart card coupler TDA8005 handbook, full pagewidth PRES OFF START fINT/64 RST CLK I/O VCC VUP ENLI t10 internal t11 t12 t13 t14 tde Fig.10 Emergency deactivation sequence after a card take-off. 1996 Sep 25 19 MBH640 Philips Semiconductors Product specification Low-power smart card coupler TDA8005 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). * The footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. Reflow soldering Even with these conditions: Reflow soldering techniques are suitable for all LQFP and QFP packages. * Do not consider wave soldering LQFP packages LQFP48 (SOT313-2), LQFP64 (SOT314-2) or LQFP80 (SOT315-1). The choice of heating method may be influenced by larger plastic QFP packages (44 leads, or more). If infrared or vapour phase heating is used and the large packages are not absolutely dry (less than 0.1% moisture content by weight), vaporization of the small amount of moisture in them can cause cracking of the plastic body. For more information, refer to the Drypack chapter in our "Quality Reference Handbook" (order code 9397 750 00192). * Do not consider wave soldering QFP packages QFP52 (SOT379-1), QFP100 (SOT317-1), QFP100 (SOT317-2), QFP100 (SOT382-1) or QFP160 (SOT322-1). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 1996 Sep 25 Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 29 Philips Semiconductors Product specification Low-power smart card coupler TDA8005 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
