A bidirectional level translator adapts the serial I/O signal between the smart card and the external controller. A built−in constant 20 kΩ typical resistor provides a high impedance state when not activated. 2 (3) VDD POWER This pin is connected to the system controller power supply and the input voltage can range from 2.7 to 6.0 V. 3 (4) CLOCK INPUT The clock signal, coming from the external controller, must have a Duty Cycle within the Min/Max limits defined by the specification (typically 50%). The built−in level shifter translates the input signal to the external SIM card voltage supply. 4 (5) RESET INPUT The RESET signal present at this pin is provided by the MPU. The internal level shifter translates the level according to the voltages applied to pin 3 and pin 12. 5 (6) IO_ENABLE INPUT This logic input pin forces SIM_IO pin to Low when IO_ENABLE = Low, leaving this signal High when IO_ENABLE = High. The signal is not latched and the SIM_IO pin is released to a logic High when IO_ENABLE = High. When this condition is met, the SIM_IO logic status depends upon the signal presence pin I/O. When the MPU uses two different channels to exchange data with the SIM card, the IO_ENABLE pin can be used to as a Write line to the external card, the I/O pin being used to Read data from the SIM card.

Neither the logic nor the functions of the SIM signals are affected by the interface. The NCN6011 does not regulate the SIM_VCC, nor does it detect the overload current. VCC Q1 Q2 20 k 20 k 200 ns 200 ns I/O Bidirectional Level Shifter The NCN6011 carries out the voltage difference between the MPU and the Smart Card I/O signals. When the start sequence is completed, and if no failures have been detected, the device becomes essentially transparent for the data transferred on the I/O line. To fulfill the ISO7816−3 specification, both sides of the I/O line have built−in pulsed circuitry to accelerate the signal rise transient. The I/O line is connected on both sides of the interface by a NMOS switch which provide the level shifter and, thanks to its relative high internal impedance, protects the Smart Card in the event of data collision. Such a situation could occur if either the MPU of the smart card forces a signal in the opposite logic level direction. SIM_IO GND Q5 I/O CONTROL LOGIC GND ENABLE Figure 7.

Typical SIM_IO Activated by ENABLE Pin, I/O = High (open drain) http://onsemi.com 8 NCN6011 Input Schmitt Triggers All the Logic Input pins have built−in Schmitt trigger circuits to prevent the NCN6011 against uncontrolled operation. The typical dynamic characteristics of the related pins are depicted in Figure 10. The output signal is guaranteed to go High when the input voltage is above 0.70*Vbat, and will go Low when the input voltage is below 0.30*Vbat. ESD Protection The NCN6011 includes silicon devices to protect the pins against the ESD spikes voltages. To cope with the different ESD voltages developed across these pins, the built−in structures have been designed to handle either 2.0 kV, when related to the microcontroller side, or 4.0 kV when connected with the external contacts. Practically, the SIM_RST, SIMD_CLK and SIM_IO pins can sustain 4.0 kV. Output Printed Circuit Board Layout Since the NCN6011 carries high speed currents together with high frequency clock, the printed circuit board must be carefully designed to avoid the risk of uncontrolled operation of the interface. Care must be observed to avoid common copper track sharing small signal and high power with a relative high impedance. On top of that, the clock signal (both input and output) shall be properly shielding to minimize the high frequency cross talk between this line and the rest of the circuit. In particular, the SIM_RST signal shall be protected from interference generated by the SIM_CLK line. Such protection can be achieved by surrounding the SIM_CLK track by a copper track connected to ground. Generally speaking, the ground plane shall be as large as possible for a given printed circuit board area. Vbat ON OFF 0.70 *Vbat 0.30 *Vbat Input Vbat Figure 10.
