Nexperia NXT4558-Q100 SIM Card Interface Level Translator

Nexperia NXT4558-Q100 SIM Card Interface Level Translator is designed to interface a SIM card with a single low-voltage host-side interface. The NXT4558-Q100 offers 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 and class-C SIM cards. An active HIGH EN pin enables the normal operation of the translator. A HIGH to LOW transition on pin EN initiates a shutdown sequence on SIM card pins by ISO-7816-3.

The Nexperia NXT4558-Q100 complies with all ETSI, IMT-2000, and ISO-7816 SIM/Smart card interface requirements.

Features

  • Support SIM cards and eSIM with supply voltages of 1.62V to 3.3V
  • Host micro-controller operating voltage range: 1.08V to 1.98V
  • 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 suppress higher harmonics of digital I/O's
  • A HIGH EN signal enables the translation of the signals
  • Low current shutdown mode <1μA
  • Supports clock speed beyond 5MHz clock
  • Pb-free, Restriction of Hazardous Substances (RoHS) compliant, and free of halogen and antimony (Dark Green compliant)
  • Latch-up performance exceeds 100mA per JESD 78 Class II Level B
  • ESD protection:
    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000V
    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000V
    • IEC61000-4-2 level 4, contact and air discharge on all SIM card-side pins are 8kV and 15kV
  • Available in 10-pin XQFN package
  • Specified from -40°C to +85°C and -40°C to 125°C

Applications

  • NXT4558-Q100 can be used with a range of SIM card-attached devices, including:
    • Telematic control units
    • SIM card interfaces
