The NXT4558-Q100 device is built for interfacing a SIM card with a single low-voltage host side interface. The NXT4558-Q100 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 NXT4558-Q100 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements.
Features and benefits
Automotive product qualification in accordance with AEC-Q100 (Grade 1)
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
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

Available in 10-pin XQFN package
Applications
NXT4558-Q100 can be used with a range of SIM card attached devices including:
Telematic Control Units
SIM card interfaces
Wireless Point-to-Sale terminals
