NXP Semiconductors NVT4558 SIM Card Interface Level Translator

NXP Semiconductor NVT4558 SIM Card Interface Level Translator interfaces host processors with operation from 1.2V to 1.8V and SIM cards from 1.8V to 3.6V. Integrated ESD circuitry protects all pins (on the card side) up to 8kV of contact ESD defined by IEC 61000-4-2, and integrated EMI filter circuitry suppresses higher harmonics of digital I/Os. Applications include cell phones, notebooks, tablets, and other portable electronic devices with a cellular connection.

Features

Supports clock speed up to 10MHz
Compliant with all ISO-7816 SIM/Smart card interface requirements
Support SIM card supply voltages with a range of 1.62V to 3.6V
Host microcontroller operating voltage range of 1.08V to 1.98V
Automatic level translation of I/O, RSTn, and CLKn between the SIM card and host side interface with capacitance isolation
Incorporated shutdown feature for the SIM card signals according to ISO-7816-3
Enable/disable through the hardware enable pin or with the automatic enable/disable feature
Integrated pull-up and pull-down resistors

Integrated EMI filters suppress higher harmonics of the digital I/Os
Integrated 8kV ESD protection according to IEC 61000-4-2, level 4 on V_CCB or any of the card side pins
Level-shifting buffers keep ESD stress away from the host (zero-clamping concept)
1.4mm x 1.8mm, 10-pin XQFN10 package with a 0.4mm pitch
Wave and reflow solderable
Pb-free, Restriction of Hazardous Substances (RoHS) compliant, and free of halogen and antimony (Dark Green compliant)
