NXT4556

SIM card interface level translator

The NXT4556 device is built for interfacing a SIM card with a single low-voltage host side interface. The NXT4556 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 NXT4556 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements.

特性

  • 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)

  • ESD protection:

    • HBM ANSI/ESDA/JEDEC JS-001 exceeds 2 kV

    • CDM ANSI/ESDA/JEDEC JS-002 exceeds 1 kV

    • 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

目标应用

  • NXT4556 can be used with a range of SIM card attached devices including:

    • Mobile and personal phones

    • Wireless modems

    • SIM card terminals
