The functional blocks are described in the following sections. It is assumed that the reader of this specification is aware of GSM11.11 and ISO 7816 terminology. I2C-bus – START/ADDRESS/WRITE – COMMAND BYTE – STOP. The fixed address is 01001XY. X and Y are defined by the logic levels on pins SAD1 and SAD0 as shown in Table 1 (connect to ground for logic 0; connect to VDDI for logic 1). The command bits are described in Table 2. The commands are executed on the rising edge of the 9th SCL pulse. control The I2C-bus interface is used: • To configure the clock to the card in active mode (1⁄2fSIMCLK and 1⁄4fSIMCLK) • To configure the clock to the card in power reduction mode (stop LOW, stop HIGH or ±1.25 MHz derived from the internal oscillator) • Status from the TDA8003TS (see Table 4). The fixed address is 01001XY. X and Y are defined by the logic levels on pins SAD1 and SAD0 as shown in Table 1. • To select operation with a 3 or 5 V card • To start or stop sessions (cold reset) Table 1 • To initiate a warm reset • To enter or leave the Power-down mode • To request the status (card present or not, hardware problem occurred, unresponsive card after activation, supply drop-out detected by the voltage supervisor, card powered or not) • To configure SIMI/O and I/O in high-impedance (for use of several TDA8003TS in parallel). 2000 Apr 20 6 Address selections ADDRESS SAD1 SAD0 48H 0 0 4AH 0 1 4CH 1 0 4EH 1 1 Philips Semiconductors Product specification I2C-bus SIM card interface Table 2 TDA8003TS Description of the command bits; (all bits are cleared at reset) SYMBOL BIT DESCRIPTION START/STOP 0 Logic 1 initiates an activation sequence and a cold reset procedure. Logic 0 initiates a deactivation sequence. WARM 1 Logic 1 initiates a warm reset procedure. TDA8003TS/C1: warm reset performed only when the 2 times 45000 CLK pulses have expired without answer from the card.

TDA8003TS/C2: Same as for C1, but the count is 2 times 44745 CLK pulses. EARLY 6 Logic 1 when a card has answered between 200 and 352 CLK cycles. Logic 0 when the status is read-out. ACTIVE 7 Logic 1 when the card is power-on. Logic 0 when the card is power-off. Note 1. In case of card extraction, supply drop-out or overload detection within a session, the card will be automatically deactivated, SIMERR pulled LOW, bit START = 0 and the corresponding status bit = 1. The status bit will be logic 0 and SIMERR will be released when the microcontroller reads out the status register, on the 7th SCL pulse. After a supply drop-out, SIMERR will be released at the end of the alarm pulse and bit SUPL = 1. 2000 Apr 20 7 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS The voltage supervisor (see Fig.3) senses VDDS. It generates an alarm pulse, whose length tW is defined by an external capacitor connected to pin DEL, when VDD is too low to ensure proper operation (1 ms per 1 nF typical). Power supply The circuit operates within a supply voltage range of 2.5 to 6 V. The supply pins are VDDS and SGND. Pins VDDP and PGND only supply the DC-to-DC converter for the analog drivers to the card and must be decoupled externally because of the large current spikes that the card and the DC-to-DC converter can create. An integrated spike killer ensures the card contacts to remain inactive during power-up or power-down. An internal voltage reference is generated for the DC-to-DC converter, the voltage supervisor and the VCC generator. During this alarm pulse, SIMERR is LOW and the I2C-bus is unresponsive. SIMERR goes back to HIGH, and the I2C-bus becomes operational at the end of this alarm pulse. Bit SUPL is set as long as the status has not been read. It is also used to either block any spurious signals on card contacts during microcontroller reset, or to force an automatic deactivation of the contacts in the event of supply drop-out. All interface signals with the microcontroller (PWROFF, SIMCLK, SAD1, SAD0, SIMERR, SCL, SDA and SIMI/O) are referenced to a separate supply pin VDDI, which may be different from VDD (1.5 ≤ VDDI ≤ 6 V). Outside a card session, SIMERR is LOW as long as the voltage supervisor is active. If a supply drop-out occurs during a session, SIMERR falls to LOW, bit START is cleared and an automatic deactivation is initiated. The pull-up resistors on bus lines SDA and SCL may be referenced to a voltage higher than VDDI. This allows the use of peripherals which do not operate at VDDI. handbook, full pagewidth VDDS DEL tW tW SIMERR status read after event I2C-bus unresponsive I2C-bus OK I2C-bus unresponsive I2C-bus OK I2C-bus unresponsive MGR436 Fig.3 Voltage supervisor. 2000 Apr 20 8 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS DC-to-DC converter Off mode The whole circuit is powered by VDDS, except for the VCC generator, the other card contact buffers and the interface signals. The Off mode is entered when the PWROFF signal is LOW. In this mode, no function is valid. This mode avoids switching off the power supply of the device, and gives a current consumption less than 2 µA. Before entering the Off mode, the card must be deactivated. The DC-to-DC converter acts as a doubler or a tripler, depending on the supply voltage VDD and the card supply voltage VCC. There are basically four possible situations: The Off mode is resumed when the PWROFF signal returns to HIGH. This re-initializes the voltage supervisor, and has the same effect as a reset of the device. As long as the device is not ready to operate, the SIMERR signal will remain LOW. • VDD = 3 V and VCC = 3 V. The DC-to-DC converter acts as a doubler with a regulation of VVUP at approximately 4.5 V • VDD = 3 V and VCC = 5 V. The DC-to-DC converter acts as a tripler with a regulation of VVUP at approximately 6.5 V Sequencer and clock counter The sequencer handles the ensuring activation and deactivation sequences in accordance with GSM11.11 and ISO 7816, even in case of emergency (card take-off, short circuit and supply drop-out). The sequencer is clocked with the internal oscillator frequency fosc. • VDD = 5 V and VCC = 3 V. The DC-to-DC converter is disabled and VDD is applied to pin VUP • VDD = 5 V and VCC = 5 V. The DC-to-DC converter acts as a doubler with a regulation of VVUP at approximately 6.5 V. The activation is initiated with the START command (only if the card is present, and if the voltage supervisor does not detect a fault on the supply). During activation, VCC goes HIGH and subsequently I/O is enabled and CLK is started with RST = LOW. The clock counter counts the CLK pulses till a start bit is detected on I/O. The supply voltage is recognized by the TDA8003TS at approximately 3.75 V for the C1 and 3.3 V for the C2. When a card session is requested by the microcontroller, the sequencer will first start the DC-to-DC converter, which is a switched capacitor type, clocked by an internal oscillator at a frequency fosc of approximately 2.5 MHz. The output voltage VVUP is regulated at approximately 4.5 or 6.5 V and subsequently fed to the VCC generator. VCC and PGND are used as a reference for all other card contacts. After 45000 CLK pulses for the C1 (44745 for the C2), if no start bit on I/O has been detected, the sequencer toggles RST to HIGH, and counts again 45000 CLK pulses (44745 for the C2). If, again, no start bit has been detected, SIMERR will be pulled LOW and the information of bit MUTE is set in the status register. Power-down mode If a start bit has been detected during the two 45000 CLK pulse slots (44745 for the C2), the clock counter is stopped, RST is kept at the same level and the session can go on between the card and the system. The Power-down mode is used for current consumption reduction when the card is in Sleep mode. To enter Power-down mode, the microcontroller must first select CLK in this mode (stop LOW, stop HIGH or 1.25 MHz from the internal oscillator) with bits CLKPD1 and CLKPD2. Subsequently, the microcontroller sends the command PDOWN, CLK is switched to the value predefined by bits CLKPD1 and CLKPD2, and SIMCLK may be stopped (HIGH or LOW). The clock counter does not take care of any start bit during the 200 first CLK pulses of both slots; if a start bit is detected between 200 and 352 CLK pulses of both slots, then SIMERR will be pulled LOW and the information of bit EARLY is set in the status register. If the selected CLK is stopped, the biasing currents in the buffers to the card will be reduced. The voltage supervisor and all control functions also remain active. The maximum current taken by the card in this mode when CLK is stopped is assumed to be less than 5 mA. The deactivation is initiated either by the microcontroller (STOP command), or automatically by the TDA8003TS in case of card take-off, short circuit or supply voltage drop-out detected by the voltage supervisor. During deactivation, RST will go LOW, CLK is stopped, I/O is disabled and VCC goes LOW. Before leaving the Power-down mode, the clock signal must first be applied to SIMCLK, and then bit PDOWN must be set to logic 0. 2000 Apr 20 9 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS If a start bit is detected on I/O and the clock counter is stopped with RST = HIGH, the card session may continue. If not, bit MUTE is set in the status register and SIMERR is pulled LOW. The microcontroller may initiate a deactivation sequence by setting bit START to logic 0. Clock circuit The clock to the card is either derived from pin SIMCLK (2 to 20 MHz) or from the internal oscillator. During a card session, fCLK may be chosen to be 1⁄ f 1 2 SIMCLK or ⁄4fSIMCLK depending on bit DT/DFN. If a start bit is detected during the 200 first CLK pulses of each count slot, then it will not be taken into account. If a start bit is detected during 200 and 352 CLK pulses of each slot, then bit EARLY is set in the status register and SIMERR is pulled LOW. The microcontroller may initiate a deactivation sequence by setting bit START to logic 0. For the card Sleep mode, CLK may be chosen stop LOW, stop HIGH or 1⁄2fosc (1.25 MHz) with bits CLKPD1 and CLKPD2. This predefined value will be applied to CLK when bit PDOWN is set to logic 1. The first CLK pulse has the correct width, and all frequency changes are synchronous, ensuring that no pulse is smaller than 45% of the shortest period. The sequencer is clocked by 1⁄64fosc which leads to a time interval T of 25 µs typically. Thus t1 = 0 to 1⁄64T; t2 = t1 + 3⁄2T; t3 = t1 + 7⁄2T; t4 = t1 + 4T and t5 depends on the SIMCLK frequency. The duty cycle is within 45 and 55% in stable state, the rise and fall times are less than 8% of the period and precaution has been taken so that there is no overshoot or undershoot. Deactivation sequence Figure 5 shows the deactivation sequence. When the session is completed, the microcontroller sets bit START to logic 0. The circuit will execute an automatic deactivation sequence: Activation sequence Figure 4 shows the activation sequence. When the card is inactive, VCC, CLK, RST and I/O are LOW, with low-impedance with respect to ground. The DC-to-DC converter is stopped. SIMI/O is pulled HIGH at VDDI via the 20 kΩ pull-up resistor. When all conditions are met (supply voltage, card present, no hardware problems), the microcontroller may initiate an activation sequence by setting bit START to logic 1 (t0) via the I2C-bus: 1. Card reset, RST falls to LOW (t10). 2. CLK is stopped (t11). 3. I/O falls to LOW (t12). 4. VCC falls to 0 V with typically 0.17 V/µs slew rate (t13). The deactivation is completed when VCC reaches 0.4 V (tde). 1. The DC-to-DC converter is started (t1). 5. The DC-to-DC converter is stopped and CLK, RST, VCC and I/O become low-impedance with respect to PGND (t14). 2. VCC starts rising from 0 to 3 or to 5 V according to 3 V/5 VN control bit with a controlled rise time of 0.17 V/µs typically (t2). Where t10 < 1⁄64T; t11 = t10 + 1⁄2T; t12 = t10 + T; t13 = t12 + 5 µs and t14 = t10 + 4T. 3. I/O buffer is enabled in reception mode (t3). 4. CLK is sent to the card reader with RST = LOW, and the count of 45000 (44745 for C2) CLK pulses is started (t4 = tact). 5. If a start bit is detected on I/O, the clock counter is stopped with RST = LOW. If not, RST = HIGH, and a new count of 45000 (44745 for C2) CLK pulses is started (t5). 2000 Apr 20 10 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS handbook, full pagewidth START VCC , I/O CLK , RST SIMI/O MGR437 t0, t1 t2 t3 t4 (= tact) t5 Answer To Reset (ATR) begin the 200 first CLK pulses are masked Fig.4 Activation sequence. handbook, full pagewidth START RST CLK I/O VCC MGR438 t10 t13 t11 tde t14 t12 Fig.5 Deactivation sequence. 2000 Apr 20 11 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS When configuration bit I/OEN is logic 0, then I/O and SIMI/O are independent, which allows parallelization of several TDA8003TS with only one I/O line on the microcontroller side (up to 4 different I2C-bus addresses). Protections The following main hardware fault conditions are monitored by the circuit: • Short circuits between VCC and other contacts When bit I/OEN is logic 1, then the data transmission between I/O and SIMI/O is enabled. • Card take-off during transaction • Supply drop-out. The first side on which a falling edge occurs becomes the master. An anti-latch circuit disables the detection of falling edges on the other side, which becomes a slave. When one of these problems is detected during a card session, the security logic block pulls SIMERR to LOW, to warn the microcontroller and initiates an automatic deactivation of the contacts (see Fig.6). After a delay time td (<500 ns) on the falling edge, the N transistor on the slave side is turned on, thus transmitting the logic 0 present on the master side. I/O circuit When the master goes back to logic 1, the P transistor on the slave side is turned on during td, and then both sides return to their Idle states. The Idle state is realized by both I/O and SIMI/O being pulled HIGH (via a 10 kΩ pull-up resistor from I/O to VCC and via a 20 kΩ pull-up resistor from SIMI/O to VDDI). The maximum frequency on these lines is 1 MHz. I/O is referenced to VCC and SIMI/O to VDDI, thus allowing operation with VCC ≠ VDD ≠ VDDI. handbook, full pagewidth START status readout SIMERR RST CLK I/O VCC MGR439 Fig.6 Emergency deactivation. 2000 Apr 20 12 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). • For packages with leads on two sides and a pitch (e): – larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. Reflow soldering The footprint must incorporate solder thieves at the downstream end. 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. • For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. 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. Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C. 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. Wave soldering Manual soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. To overcome these problems the double-wave soldering method was specifically developed. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. 2000 Apr 20 20 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE WAVE BGA, LFBGA, SQFP, TFBGA not suitable suitable(2) HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, SMS not PLCC(3), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO REFLOW(1) suitable suitable suitable not recommended(3)(4) suitable not recommended(5) suitable Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”. 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 2000 Apr 20 21 Philips Semiconductors Product specification I2C-bus SIM card interface TDA8003TS DATA SHEET STATUS DATA SHEET STATUS PRODUCT STATUS DEFINITIONS (1) Objective specification Development This data sheet contains the design target or goal specifications for product development.
