NXT455 Sim Card Voltage Translator
Nexperia sim card voltage translator features a host microcontroller operating voltage range of 1.08 V to 1.98 V
Nexperia NXT455* device is built for interfacing a SIM card with a single low-voltage host-side interface. The NXT455* has three level translators to convert the data, RST, and CLK signals between a SIM card and a host microcontroller. It offers a high-speed level translation capable of supporting Class-B and Class-C SIM cards.
The NXT455* is compliant with all ETSI, IMT-2000, and ISO-7816 SIM/smart card interface requirements.
- Support SIM cards and eSIM with supply voltages of 1.62 V to 3.3 V
- Host microcontroller 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 shutdown when VCC_SIM powers down
- Integrated pull-up resistors with no external resistor required
- Integrated EMI filters suppress higher harmonics of digital I/Os
- Low-current shutdown mode less than 1 μA
- Supports clock speed beyond 5 MHz clock
- Pb-free, restriction of hazardous substances, RoHS-compliant, and free of halogen or 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 2,000 V
- CDM: ANSI/ESDA/JEDEC JS-002 Class C3 exceeds 1,000 V
