TDA8005A
* Control and communication through a standard RS232 full-duplex interface * Optional additional I/O ports for: - keyboard - LEDs - display - etc. * P80CL51 microcontroller core with 4-kbyte ROM and 256-byte RAM. APPLICATIONS * Portable smart card readers for protocol T = 0 * GSM mobile phones. GENERAL DESCRIPTION The TDA8005A is a low-cost card interface for portable smart card readers. Controlled through a standard serial interface, it takes care of all ISO 7816 and GSM11.11 requirements for both 5 and 3 V cards. It gives the card and the set a very high level of security, due to its special hardware against ESD, short-circuiting, power failure, etc. Its integrated step-up converter allows operation within a supply voltage range of 2.5 to 6 V. The very low power consumption in power-down and sleep modes saves battery power. Development tools, application report and support (hardware and software) are available.

FUNCTIONAL DESCRIPTION Microcontroller The microcontroller is a P80CL51 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. This means that the division factor of 32 in the formula is replaced by 8 in both reception and transmission mode and that in the reception modes only four samples per bit are taken with decision on the majority of samples 2, 3 and 4; the delay counter has been reduced from 1536 to 24 as well. Remark: this has an impact when getting out of power-down mode. It is recommended to switch to internal clock before entering power-down mode. All the other functions remain unchanged. Refer to the P80CL51 data sheet for any further information. Internal ports INT0 (P32), P10, P04 to P07 and P24 to P27 are used for controlling the smart card interface. Mode 0 is unchanged. The baud rate for modes 1 and 3 is:
SMOD f clk 2 ---------------- x ---------------------------------------------8 12 x ( 256 - TH1 )
TDA8005A
Supply The circuit operates within a supply voltage range of 2.5 to 6 V. The supply pins are VDDD, VDDA, 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 voltage supervisor generates an internal 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. 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 dropout; see Sections "Activation sequence" and "Deactivation sequence". 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.
The baud rate for mode 2 is: 2 ---------------- x f clk 16 For mode 3 timing see Table 1.

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 VDDD. 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 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 of approximately 2.5 MHz. The output voltage Vstep-up is regulated at approximately 6.5 V and then fed to the VCC generator. VCC and DGND are used as a reference for all other cards contacts.
The step-up converter may be chosen as a doubler or a tripler by mask option, depending on the voltage and the current needed on the card. 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; see Table 3) 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 (internal signal; port P04), allowing the correct count of CLK pulses during answer-to-reset from the card. The presence of the card is signalled to the controller by the OFF signal (port P10; see Table 3). 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.

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). Directly after reset and during power reduction modes the microcontroller clock frequency fclk equals 18fINT; fINT 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. Cards clock: the microcontroller may select to send the card a card clock frequency of 12fXTAL, 14fXTAL, 18fXTAL or 1 f 2 INT (1.25 MHz), or to stop the clock HIGH or LOW. All transitions are synchronous, ensuring correct pulse length during start or change in accordance with ISO 7816.

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). 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 Vstep-up. When the microcontroller is in power-down mode any change on P1 ports or on PRES will wake up the circuit. In both power reduction modes the sequencer is active, allowing automatic emergency deactivation in the event of card take-off, hardware problems, or supply dropout. The TDA8005A is set into power-down or sleep mode by software. There are several ways to return to normal mode: insertion 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 signal on XTAL1, it may stop this clock after setting the device into power-down mode and then wake it up when sending the clock signal again. In this situation, the internal clock should have been used before the fclk. Peripheral interface This block allows synchronous serial communication with the three peripherals (ISO 7816 UART, clock circuitry and output port extension); see Figs 1 and 5.
After power on, CLK is set at STOP LOW and fclk is set at 8fINT.
Power-down and sleep modes The TDA8005A offers a large flexibility for defining power reduction modes by software. Some configurations are described below. In the power-down mode, the microcontroller is in power-down and the supply and the internal oscillator are

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 Elementary Time Unit (ETU) timing (in the reception mode the bit is sampled at 1 ETU). It also allows the cards clock frequency changes 2 without interfering with the baud rate. 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 following occurs in the reception mode (see Fig.6): * Detection of the inverse or direct convention at the beginning of Answer To Reset (ATR) * Automatic convention setting, so the microcontroller only receives characters in direct convention * Parity checking and automatic request for character repetition in case of error (reception is possible at 12 ETU).

The following occurs 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 * 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.) in accordance with peripheral interface. The register is reset when its status is read by the microcontroller. The ISO UART configuration register enables the microcontroller to configure the ISO UART and to choose between 5 or 3 V cards. Bit UC4 (3 V/5 V) LOW means 5 V card, bit UC4 (3 V/5 V) HIGH means 3 V card; conform peripheral interface. The selection of 3 or 5 V card has to be done before activation. 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 UC1 (START SESSION) and UC0 (ISO UART RESET) in the UART configuration register and then sets bit START SESSION LOW. When the first start bit on I/O is detected (sampling rate fclk/31), the UART sets the bit US2 (first start bit detected) in the status register which gives an interrupt on internal port INT0 one clock pulse later.
TDA8005A
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. Bit UC1 (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. If no parity error is detected, the UART sets bit US1 (UART receive 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. 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 US1 (UART receive buffer full) and US3 (parity error detected during reception of a character) in the status register which warns the microcontroller that an error has occurred. The card is supposed to repeat the previous character.

Low-power (3 V/5 V) smart card coupler
When the controller needs to transmit data to the card, it first sets bit UC3 in the UART configuration register 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, 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. If no error has occurred, the UART sets bit US0 (UART transmit 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. If an error has occurred, it sets bits US0 and US4 (parity error detected during transmission of a character) which warns the microcontroller to rewrite the previous character in the UART transmit register.
TDA8005A
If the character has been rewritten before 13 ETU, the transmission will start at 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 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. Bit UC3 (TRANSMIT/RECEIVE) must be reset to enable the reception of the characters to follow. When the session is completed, the microcontroller re-initializes the whole UART by resetting bit UC0 (ISO UART RESET).

I/O buffer modes (see Fig.8) The I/O buffer modes are: * I/O buffer disabled * I/O buffer in input, 20 k pull-up resistor connected between I/O and VCC, I/O masked till 200 clock pulses * I/O buffer in input, 20 k pull-up resistor connected between I/O and VCC, I/O is sampled every 31 clock pulses * I/O buffer in output, 20 k pull-up resistor connected between I/O and VCC * I/O buffer in output, I/O is pulled LOW by the N transistor of the buffer * I/O buffer in output, I/O is pulled HIGH or LOW by the P or N transistor. Output ports extension 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 (in accordance with use in software document). 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 conditions are fulfilled (supply voltage present, card present, no hardware problems), the microcontroller may initiate an activation sequence by setting START LOW (t0; see Fig.9): 1. The step-up converter is started (t1) 2. LIS signal is disabled by internal signal ENLI, and VCC starts rising from 0 to 5 or 3 V (according to bit 4 of UART configuration register) with a controlled rise time of 0.1 V/s typically (t2) 3. I/O buffer is enabled (t3) 4. Clock is sent to the card (t4) 5. RST buffer is enabled (t5).
TDA8005A
In order to allow a precise count of clock pulses during ATR, a defined time window (t3; t5) is opened where the clock may be sent to the card by means of RSTIN (port P04). Beyond this window, RSTIN has no more action on clock, and only monitors the cards RST contact (RST is the inverse of RSTIN). 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 + 32T, t3 = t1 + 4T, t4 = t3 to t5 and t5 = t1 + 7T. Deactivation sequence When the session is completed, the microcontroller sets START HIGH. The circuit then executes an automatic deactivation sequence (see Fig.10): 1. Card reset (RST falls LOW) at t10 2. Clock is stopped at t11 3. I/O becomes high impedance to the ISO UART (t12) 4. VCC falls to 0 V with typical 0.1 V/s slew rate (t13) 5. The step-up converter is stopped and CLK; RST, VCC and I/O become low impedance to GND (t14) 6. t10 < 164T; t11 = t10 + 12T; t12 = t10 + T; t13 = t10 + 32T; t14 = t10 + 5T. Protections Main hardware fault conditions are monitored by the circuit: * Overcurrent on VCC (in accordance with options as specified in Table 3) * 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 (port P10) 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 until a card is inserted.

SOLDERING Introduction 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. 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). Reflow soldering Reflow soldering techniques are suitable for all LQFP and QFP packages. 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). 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. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 50 and 300 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. Wave soldering Wave soldering is not recommended for LQFP and QFP packages. 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. CAUTION Wave soldering is NOT applicable for all LQFP and QFP packages with a pitch (e) equal or less than 0.5 mm.
TDA8005A
If wave soldering cannot be avoided, for LQFP and QFP packages with a pitch (e) larger than 0.5 mm, 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. * The footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. 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. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 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.
