Introduction

AI Translation

The NXT4557 device is built for interfacing a SIM card with a single low-voltage host side interface. The NXT4557 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. An active HIGH EN pin enables normal operation of the translator. A HIGH to LOW transition on pin EN initiates a shutdown sequence on SIM card pins in accordance with ISO-7816-3. The NXT4557 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements.

Features

AI Translation
  • 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
  • A HIGH EN signal enables the translation of the signals
  • 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 are 8 kV and 15 kV
  • Available in 10-pin XQFN package
