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).

Description
Power Down Mode pin:
STOP = Low ³ Low current shutdown mode activated
STOP = High ³ Normal Operation
A Low level on this pin resets the SIM interface, switching off the SIM_VCC.
The signal present on this pin programs the SIM_VCC value:
MOD_VCC = Low ³ SIM_VCC = 1.8 V
MOD_VCC = High ³ SIM_VCC = 3 V
This pin is connected to the system controller power supply. It configures the level shifter input
stage to accept the signals coming from the microprocessor. A 0.1 mF capacitor shall be used to
bypass the power supply voltage. When VDD is below 1.1 V typical the SIM_VCC is disabled. The
NCN4555 comes into a shutdown mode.
No Connect
DC−DC converter supply input. The input voltage ranges from 2.7V up to 5.5V. This pin has to be
bypass by a 0.1 mF capacitor.
No Connect
This pin is connected to the SIM card power supply pin. 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.
This pin handles the connection to the serial I/O of the card connector. A bidirectional level
translator adapts the serial I/O signal between the card and the micro controller. A 14 kW (typical)
pullup resistor provides a High impedance state for the SIM card I/O link.
This pin is connected to the RESET pin of the card connector. A level translator adapts the
external Reset (RST) signal to the SIM card.
This pin is the GROUND reference for the integrated circuit and associated signals. Care must be
taken to avoid voltage spikes when the device operates in a normal operation.
This pin is connected to the CLOCK pin of the card connector. The CLOCK (CLK) signal comes
from the external clock generator, the internal level shifter being used to adapt the voltage defined
for the SIM_VCC.
No Connect
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 through the internal level
shifter which translates the level according to the SIM_VCC programmed value.
This pin is connected to an external microcontroller or cellular phone management unit. A
bidirectional level translator adapts the serial I/O signal between the smart card and the external
controller. A built−in constant 18 kW (typical) resistor provides a high impedance state when not
activated.
