Nexperia NXT4558-Q100 SIM Card Interface Level Translator
Nexperia NXT4558-Q100 SIM Card Interface Level Translator is designed to interface a SIM card with a single low-voltage host-side interface. The NXT4558-Q100 offers 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 and class-C SIM cards. An active HIGH EN pin enables the normal operation of the translator. A HIGH to LOW transition on pin EN initiates a shutdown sequence on SIM card pins by ISO-7816-3.The Nexperia NXT4558-Q100 complies with all ETSI, IMT-2000, and ISO-7816 SIM/Smart card interface requirements.
Features
- Support SIM cards and eSIM with supply voltages of 1.62V to 3.3V
- Host micro-controller operating voltage range: 1.08V to 1.98V
- 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 suppress higher harmonics of digital I/O's
- A HIGH EN signal enables the translation of the signals
- Low current shutdown mode <1μA
