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
- 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 8kV and 15 kV
- Available in 10-pin XQFN package
- NXT4557 can be used with a range of SIM card attached devices including:
- Mobile and personal phones
- Wireless modems
- SIM card terminals
