No Connection. (TSSOP−14 Only)
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
built−in constant 20 kΩ 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 built−in 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.

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 kΩ typical pull up resistor provides a High impedance
state for the SIM card I/O link.
