NXT4559UP

SIM card interface level translator

The NXT4559 device is built for interfacing a SIM card with a single low-voltage host side interface. The NXT4559 has three level translators to convert the data, RST and CLK signals between a SIM card and a host microcontroller. A high speed level translation capable of supporting class-B, class-C SIM cards. VCC_SIM power-down initiates a shutdown sequence on SIM card pins in accordance with ISO-7816-3.

The NXT4559 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements.

Features and benefits

  • Support SIM cards and eSIM with supply voltages 1.62 V to 3.3 V

  • Host micro-controller operating voltage range: 1.08 V to 1.98 V

  • Automatic level translation of I/O, RST and CLK between SIM card and host side interface with capacitance isolation

  • Incorporates shutdown feature for the SIM card signals according to ISO-7816-3

  • High Vdis(UVLO_AC) switching level, arranging quick shut down when VCC_SIM powers down

  • Integrated pull-up resistors; no external resistor required

  • Integrated EMI Filters suppresses higher harmonics of digital I/O's

  • Low current shutdown mode < 1 μA

  • Supports clock speed beyond 5 MHz clock

  • Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green compliant)

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

    • IEC61000-4-2 level 4, contact and air discharge on all SIM card-side pins exceeds 8 kV and 15 kV

  • Available in 9-pin wafer level chip-scale package (WLCSP); 9 bumps; 1.06 mm x 1.06 mm x 0.43 mm body; 0.35 mm pitch

  • Specified from -40 °C to +85 °C

Applications

  • NXT4559 can be used with a range of SIM card attached devices including:

    • Mobile and personal phones

    • Wireless modems

    • SIM card terminals

Sample

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
