PIN DESCRIPTIONS
Pin 1 Name VDD Type POWER Description This pin is connected to the system controller power supply suitable to operate from a 3.6 V typical battery. A low ESR ceramic capacitor (4.7 mF typical) shall be used to bypass the power supply voltage. A Low level on this pin resets the SIM interface, switching off the SIM_VCC, according to the ISO7816-3 Power Down procedure (See Table 1 and Figure 3). The signal present on this pin programs the SIM_VCC value (See Table 1): MOD_VCC = L SIM_VCC = 5.0 V MOD_VCC = H SIM_VCC = 3.0 V The signal present on this pin controls the SIM_VCC state (See Table 1): PWR_ON = L SIM_VCC = Open, no supply connected to the SIM card. PWR_ON = H SIM_VCC = Active, the card is powered. This pin is connected to an external microcontroller or GSM management unit. A bi-directional level translator adapts the serial I/O signal between the smart card and the external controller. A built-in constant 20 k (typical) resistor provides a high impedance state when not activated. The clock signal, coming from the external controller, must have a Duty Cycle within the Min/Max values defined by the specification (typically 50%). The built-in level shifter translates the input signal to the external SIM card CLK input. The RESET signal present at this pin is connected to the SIM card. The internal level shifter translates the level according to the voltages present at pin 1 and the SIM_VCC programmed value. This pin is connected to the RESET pin of the card connector. A level translator adapts the external RESET signal to the SIM card. A built-in active pull down connects this pin to ground when the device is in a nonoperating mode. This pin is connected to the CLK pin of the card connector. The CLOCK signal comes from the external clock generator, the internal level shifter being used to adapt the voltage defined for the SIM_VCC. A built-in active pull down connects this pin to ground when the device is in a nonoperating mode. This pin is the GROUND reference for the integrated circuit and associated signals. Cares must be observed to avoid voltage spikes when the device operates in a normal operation. This pin handles the connection to the serial I/O of the card connector. A bi-directional level translator adapts the serial I/O signal between the card and the microcontroller. A 20 k (typical) pull up resistor provides a High impedance state for the SIM card I/O link. POWER POWER POWER This pin is connected to the external capacitor used by the internal Charge Pump converter. Using Low ESR ceramic type is recommended (X5R or X7R). This pin is connected to the external capacitor used by the internal Charge Pump converter. Using Low ESR ceramic type is recommended (X5R or X7R). This pin is connected to the SIM card power supply pin. An internal Charge Pump converter is programmable by the external MPU to supply either 3.0 V or 5.0 V output voltage. An external 1.0 F minimum ceramic capacitor (ESR t 100 mW, X5R or X7R recommended) must be connected across SIM_VCC and GND. During a normal operation, the SIM_VCC voltage can be set to 3.0 V followed by a 5.0 V value, or can start directly to any of these two values. When the voltage is adjusted downward (from 5.0 V to 3.0 V) cares must be observed as reverse peak current can flow from the external capacitors to the battery during a short amount of time (in the 1.0 s range). When such a voltage adjustment is necessary, it is recommended to force SIM_VCC to zero, wait 350 s minimum, then reprogram the chip to get SIM_VCC = 3.0 V.

NCN6010
Card Supply Charge Pump Converter The NCN6010 device provides three pins to control the operation of the interface as depicted in Table 1. The built-in charge pump converter circuit provides either a 3.0 V or a 5.0 V output voltage as defined by the programming mode. The external capacitor connected across pins 12 and 13 is used to generate the step up voltage. Since the device operates at 800 kHz typically, one must use high quality, Low ESR type, ceramic capacitor (220 nF recommended). The second external capacitor, connected across pin 14 and GND, smooths the output voltage coming from the Charge Pump. A high quality, Low ESR capacitor is necessary to achieve the SIM_VCC ripple voltage (1.0 F Ceramic type is recommended). The setting of the SIM_VCC voltage, using MOD_VCC = 0 or 1, can only be made when PWR_ON is Low. Consequently, a new supply voltage adjustment is performed by first deactivating the SIM card, followed by reactivating it with the new supply voltage. The SIM_VCC voltage can be reprogrammed straightforward when the output voltage increases from 3.0 V to 5.0 V. On the other hand, although it is possible to change the SIM_VCC voltage from 5.0 V to 3.0 V, it is recommended to switch off the Charge Pump prior to reprogram the SIM_VCC voltage from the high 5.0 V to a low 3.0 V. The DC/DC converter operates under two modes as defined by the logic level present at MOD_VCC/pin 3: MOD_VCC = 0 SIM_CC = 5.0 V, "10%. This is the default condition at start up. MOD_VCC = 1 The Charge Pump is not activated and the SIM_VCC voltage is equal to the VDD supply minus the internal maximum 50 mV drop. The NCN6010 provides a POWER DOWN sequence, according to the ISO7816-3 specification. Since a built-in active pull down MOS pull the SIM_VCC pin to ground when the smart card is deactivated, a 350 s minimum delay must be observed prior to reactivate the power supply. This timing assumes a 1.0 F external reservoir capacitor connected across SIM_VCC and Ground.

Table 1: Programming Mode
When the card is removed, the STOP pin shall be asserted Low to disable the NCN6010. A mechanical switch, or equivalent, can be either sensed by the MPU, or directly connected to pin 2, to handle the procedure. Power Up Sequence When the charge pump is activated, MOD_VCC = Low, the SIM card related level shifter pins are biased to the 5.0 V
voltage. When the output voltage starts from zero, as depicted in Figure 3, a 50 ms stabilization delay (typical) is necessary to make sure all the output signals are biased at the nominal 5.0 V voltage. To avoid a card transaction error, the user must take this delay into account and program the chip accordingly.

Figure 3. Power On Sequence
Power Down Operation The power down mode can be initiated by either the PWR_ON or by the STOP pin condition. In both cases, the communication I/O session is terminated immediately, according to the ISO7816-3 sequence as depicted in Figure 4. When the PWR_ON signal is set Low, the NCN6010 goes to the power down mode. According to the ISO7816-3 procedure defined to deactivate the SIM contacts, the input pins I/O, CLOCK and RESET must be Low before the PWR_ON is taken Low. When the
PWR_ON is Low, the SIM_IO, SIM_CLK and SIM_RST pins are forced to Low and the SIM_VCC pin is left floating. When the STOP signal is Low, the SIM_IO, SIM_CLK and SIM_RST are forced Low, the SIM_VCC being left floating, until the STOP pin is taken High again. When the card is extracted, the external MPU shall detect the operation and run the Power Down of the card by forcing PWR_ON input to Low. The NCN6010 fulfills the power sequence as defined by the ISO/CEI 7816-3 norm (see oscillogram given in Figure 5).

Level Shifters When the SIM card voltage is either higher or lower than the MPU VDD supply, the level shifters can be reprogrammed to cope with the expected output voltage. When the MPU and the SIM card operate under the same supply voltage, the DC/DC converter is not activated (SIM_VCC = VDD -50 mV) and the signals go directly through the level shifters.
VDD
The bi-directional I/O line provides a way to automatically adapt the voltage difference between the CU and the SIM card. In addition with the pull up resistor, an active pull up circuit (Figure 6 Q1 and Q2) provides a fast charge of the stray capacitance, yielding a rise time fully within the ISO/EMV specifications.

The typical waveform provided in Figure 7 shows how the accelerator operates. During the first 200 ns (typical), the slope of the rise time is solely a function of the pull up resistor associated with the stray capacitance. During this period, the PMOS devices are not activated since the input voltage is below their Vgs threshold. When the input slope
crosses the Vgsth, the opposite one shot is activated, providing a low impedance to charge the capacitance, thus increasing the rise time as depicted in Figure 7. The same mechanism applies for the opposite side of the line to make sure the system is optimum.

Input Schmitt Triggers All the Logic Input pins have built-in Schmitt trigger circuits to prevent the NCN6010 against uncontrolled operation. The typical dynamic characteristics of the related pins are depicted in Figure 8.

When the output voltage is programmed to 3.0 V, the clocks are inactive and the load is directly connected to the battery by means of switch S5. The SIM_VCC voltage follows the input value, minus the drop coming from the internal resistance . The current is limited by the Ron of the power device S5 and t he output voltage will decrease as the load current increases above 20 mA (typical). Figure 10 illustrates the theoretical waveforms.

When the NCN6010 is programmed in the 5.0 V output voltage, the clocks are activated, switch S5 is disconnected and the output voltage is the result of the C1 charge transfer into the output load. The current is limited by three mains parameters: - the Ron of the switching MOS (S1 through S4) - the operating frequency - the C1/C2 ratio and their ESR The first parameters are depending upon the internal structure and size of the NMOS/PMOS devices used to
design the chip. The third parameter is adjustable by the user and, beside the micro farad values, the type of capacitors plays a significant role. As a matter of fact, using a low cost electrolytic model will ruin the efficiency due to the high ESR of such a capacitor. It is highly recommended to use ceramic types, preferably from the X5R or X7R series, to achieve the efficiency and the SIM_VCC output voltage ripple. Table 2 summarizes the characteristics of the most common type of capacitors.

It is clear that, with nearly half an ohm of resistance is series with the pure capacitor, the tantalum or the electrolytic type will generate high voltage spikes and poor regulation in the high frequency operating charge pump built into the NCN6010. Moreover, with ESR in the 3.0 Ohm range, low cost capacitors are not suitable for this application. Figure 11 provides the schematic diagram of the simulated charge pump circuit. Although this schematic does not

The ABM devices S1, S2, S4 and S5 have been defined in the PSPICE model to represent the NMOS and PMOS used in the silicon. The ESR value of C2 and C3 can be adjusted, at PSPICE level, to cope with any type of external capacitors and are useful to double check the behavior of the system as a function of the external passives components.

The layout of the PCB is a key parameter to avoid the voltage spikes that could pollute the rest of the system. Figure 16 represents a typical printed circuit lay out, based on the schematic diagram given in Figure 14, highlighting the large ground plane used in this engineering tool. Obviously, a GSM application will use much less area, but cares must be observed to locate the capacitors as close as possible to the integrated circuit associated pins. Capacitors C1, C2, C3, C4 and C5 are ceramic, X7R, 10 V, surface mount.
