NCN6010
SIM Card Supply and
Level Shifter
The NCN6010 is a level shifter analog circuit designed to translate
the voltages between a SIM Card and an external microcontroller. A
built–in DC/DC converter makes the NCN6010 useable to drive any
type of SIM card. The device fulfills the GSM 11.11 specification. The
external MPU has an access to a dedicated input STOP pin, providing
a way to switch off the power applied to the SIM card in case of failure
or when the card is removed.
Features
• Supports 3.0 V or 5.0 V Operating SIM Card
• Built–in Pull Up Resistor for I/O Pin in Both Directions
• All Pins are Fully ESD Protected, According to GSM Specification
• Supports 10 MHz Clock
• 6.0 kV ESD Proof on SIM Card Pins
Typical Applications
• Cellular Phone SIM Interface
• Identification Module

Description
This pin is connected to the system controller power supply suitable to operate from
a 3.6 V typical battery. A low ESR ceramic capacitor (4.7 mF typical) shall be used to
bypass the power supply voltage.
A Low level on this pin resets the SIM interface, switching off the SIM_VCC,
according to the ISO7816–3 Power Down procedure (See Table 1 and Figure 3).
The signal present on this pin programs the SIM_VCC value (See Table 1):
MOD_VCC = L → SIM_VCC = 5.0 V
MOD_VCC = H → SIM_VCC = 3.0 V
The signal present on this pin controls the SIM_VCC state (See Table 1):
PWR_ON = L → SIM_VCC = Open, no supply connected to the SIM card.
PWR_ON = H → SIM_VCC = Active, the card is powered.
This pin is connected to an external microcontroller or GSM management unit. A
bi–directional 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.
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. The internal level
shifter translates the level according to the voltages present at pin 1 and the
SIM_VCC programmed value.
This pin is connected to the RESET pin of the card connector. A level translator
adapts the external RESET signal to the SIM card. A built–in active pull down
connects this pin to ground when the device is in a nonoperating mode.
This pin is connected to the CLK pin of the card connector. The CLOCK signal
comes from the external clock generator, the internal level shifter being used to
adapt the voltage defined for the SIM_VCC. A built–in active pull down connects this
pin to ground when the device is in a nonoperating mode.
This pin is the GROUND reference for the integrated circuit and associated signals.
Cares must be observed to avoid voltage spikes when the device operates in a
normal operation.
This pin handles the connection to the serial I/O of the card connector. A
bi–directional 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.
This pin is connected to the external capacitor used by the internal Charge Pump
converter. Using Low ESR ceramic type is recommended (X5R or X7R).
This pin is connected to the external capacitor used by the internal Charge Pump
converter. Using Low ESR ceramic type is recommended (X5R or X7R).
This pin is connected to the SIM card power supply pin. An internal Charge Pump
converter is programmable by the external MPU to supply either 3.0 V or 5.0 V
output voltage. An external 1.0 µF minimum ceramic capacitor (ESR t 100 mW,
X5R or X7R recommended) must be connected across SIM_VCC and GND.
During a normal operation, the SIM_VCC voltage can be set to 3.0 V followed by a
5.0 V value, or can start directly to any of these two values. When the voltage is
adjusted downward (from 5.0 V to 3.0 V) cares must be observed as reverse peak
current can flow from the external capacitors to the battery during a short amount of
time (in the 1.0 µs range). When such a voltage adjustment is necessary, it is
recommended to force SIM_VCC to zero, wait 350 µs minimum, then reprogram the
chip to get SIM_VCC = 3.0 V.
