Description
I/O
This pin is connected to an external microcontroller. A bidirectional level translator adapts the serial I/O signal between the smart card and the external controller. A builtin constant 20 k typical resistor provides a high impedance state when not activated. This pin is connected to the system controller power supply and the input voltage can range from 2.7 to 6.0 V. 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 builtin level shifter translates the input signal to the external SIM card voltage supply. 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. 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. No Connection. (TSSOP14 Only) No Connection. (TSSOP14 Only) This pin is the GROUND reference for the integrated circuit and associated signals. High frequency layout techniques are requested to connect the GND pin to the external functions. This pin is connected to the RST pin of the card connector. A voltage level translator adapts the external RESET signal (coming from the MPU) to the smart card. This pin is connected to the CLK pin of the card connector. The CLOCK signal comes from the external clock generator. The internal voltage level shifter adapts the clock signal flowing through this link. Care must be observed to prevent AC coupling with adjacent lines and signals PCB tracks. This pin is connected to the smart card VCC power supply pin. The voltage, provided by an external power supply, can range from 2.7 V to 6.0 V. The NCN6011 does not regulate or protect the voltage supply applied to the external card. This pin handles the connection to the serial I/O of the card connector. A bidirectional voltage 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. No Connection. (TSSOP14 Only)
