NCN4555 1.8V / 3V SIM Card Power Supply and Level Shifter The NCN4555 is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU. A built−in LDO−type DC−DC converter makes the NCN4555 useable to drive 1.8 V and 3.0 V SIM card. The device fulfills the ISO7816−3 smart card interface standard as well as GSM 11.11 and related (11.12 and 11.18) and 3G mobile requirements (IMT−2000/3G TS 31.101). With the STOP pin a low current shutdown mode can be activated making the battery life longer. The Card power supply voltage (SIM_VCC) is selected using a single pin (MOD_VCC). http://onsemi.com QFN−16 MN SUFFIX CASE 488AK 1 Features • • • • • • • Supports 1.8 V or 3.0 V Operating SIM Card The LDO is able to Supply More than 50 mA under 1.8 V and 3.0 V Built−in Pullup Resistor for I/O Pin in Both Directions All Pins are Fully ESD Protected According to ISO−7816 Specifications – ESD Protection on SIM Pins in Excess of 7 kV (Human Body Model) Supports up to More than 5 MHz Clock Low−Profile 3x3 QFN−16 Package Pb−Free Packages are Available* MARKING DIAGRAM ÇÇÇ ÇÇÇ 16 1 NCN 4555 ALYWG G Typical Applications • • • • SIM Card Interface Circuit for 2G, 2.5G and 3G Mobile Phones Identification Module Smart Card Readers Wireless PC Cards 1.8 V to 5.5 V 2.7 V to 5.5 V 0.1mF 0.1mF GND 3 1 P3 P2 P1 P0 2 14 13 15 ORDERING INFORMATION 5 VDD STOP MOD_VCC RST NCN4555 MPU or Microcontroller VBB CLK SIM_VCC SIM_RST SIM_CLK I/O SIM_I/O GND SIM Card Detect GND A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) 7 1 2 3 4 9 11 VCC GND RST CLK I/O C4 C8 DET 8 5 6 7 8 DET 1mF 10 Device Package Shipping † NCN4555MN QFN−16 123 Units / Rail NCN4555MNG QFN−16 (Pb−Free) 123 Units / Rail NCN4555MNR2 QFN−16 3000/Tape & Reel QFN−16 (Pb−Free) 3000/Tape & Reel NCN4555MNR2G GND †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.

An internal LDO converter is programmable by the external MPU to supply either 1.8 V or 3.0 V output voltage. An external 1.0 mF minimum ceramic capacitor recommended must be connected across SIM_VCC and GND. During a normal operation, the SIM_VCC voltage can be set to 1.8 V followed by a 3.0 V value, or can start directly to any of these two values. 8 SIM_I/O INPUT/ OUTPUT This pin handles the connection to the serial I/O of the card connector.

At the input, VBAT will be bypassed to the ground with a 0.1 mF ceramic capacitor. The NCN4555 interface DC−DC converter is a Low Dropout Voltage Regulator capable of suppling a current in excess of 50 mA under 1.8 V or 3.0 V. This device features a very low quiescent current typically lower than 25 mA (Figure 6 and 7). MOD_VCC is a select input allowing a logic level signal to select a regulated voltage of 1.8 V (MOD_VCC = LOW) or 3.0 V (MOD_VCC = HIGH). Additionally, the NCN4555 has a shutdown input allowing it to turn off or turn on the regulator output. The shutdown mode power consumption is typically in the range of a few tens of nA (30 nA Typical). Figure 8 shows a simplified view of the NCN4555 voltage regulator. The SIM_VCC output is internally current limited and protected against short circuits. The short−circuit current IVCC is constant over the temperature and SIM_VCC. It varies with VBAT typically in the range of 60 mA to 90 mA (Figure 4 and 5). LEVEL SHIFTERS The level shifters accommodate the voltage difference that might exist between the microcontroller and the smart card. The RESET and CLOCK level shifters are monodirectional and feature both the same architecture. The bidirectional I/O line provides a way to automatically adapt the voltage difference between the MCU and the SIM card in both directions. In addition with the pullup resistor, an active pullup circuit (Figure 8, Q1 and Q2) provides a fast charge of the stray capacitance, yielding a rise time fully within the ISO7816 specifications.

Basic I/O Line Interface http://onsemi.com 8 NCN4555 ESD PROTECTION The typical waveform provided in Figure 10 shows how the accelerator operates. During the first 200 ns (typical), the slope of the rise time is solely a function of the pullup 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 10. The same mechanism applies for the opposite side of the line to make sure the system is optimum. The NCN4555 SIM interface features an HBM ESD voltage protection in excess of 7 kV for all the SIM pins (SIM_IO, SIM_CLK, SIM_RST, SIM_VCC and GND). All the other pins (microcontroller side) sustain at least 2 kV. These values are guaranteed for the device in its full integrity without considering the external capacitors added to the circuit for a proper operating. Consequently in the operating conditions it is able to sustain much more than 7 kV on its SIM pins making it perfectly protected against electrostatic discharge well over the HBM ESD voltages required by the ISO7816 standard (4 kV). INPUT SCHMITT TRIGGERS PRINTED CIRCUIT BOARD LAYOUT All the Logic input pins (excepted I/O and SIM_I/O, See Figure 3) have built−in Schmitt trigger circuits to prevent the NCN4555 against uncontrolled operation. The typical dynamic characteristics of the related pins are depicted Figure 11. The output signal is guaranteed to go High when the input voltage is above 0.7 x VDD, and will go Low when the input voltage is below 0.2 x VDD or 0.4 V depending on the input considered (see the Digital Input Table on page 5). Careful layout routing will be applied to achieve a good and efficient operating of the device in its mobile or portable environment and fully exploit its performance. The bypass capacitors have to be connected as close as possible to the device pins (SIM_VCC, VDD or VBAT) in order to reduce as much as possible parasitic behaviors (ripple and noise). It is recommended to use ceramic capacitors. The exposed pad of the QFN−16 package will be connected to the ground as well as the unconnected pins (NC). A relatively large ground plane is recommended. Figures 12 and 13 shows an example of PCB device implementation in an evaluation environment. SHUTDOWN OPERATING In order to save power or for other purpose required by the application it is possible to put the NCN4555 in a shutdown mode by setting Low the pin STOP. On the other hand the device enters automatically in a shutdown mode when VDD becomes lower than 1.1 V typically. OUTPUT VDD ON OFF INPUT 0.2 x VDD or 0.4 V Figure 10.
