NXT4559
SIM card interface level translator
The NXT4559 device is built for interfacing a SIM card with a single low-voltage host side interface. The NXT4559 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 NXT4559 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements.
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
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)
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
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
Specified from -40 °C to +85 °C
