NVT4555 SIM card interface level translator and supply voltage LDO Rev. 2 24 May 2013 Product data sheet 1. General description The NVT4555 device is built for interfacing a SIM card with a single low-voltage host side interface. The NVT4555 contains an LDO that can deliver two different voltages, 1.8 V or 2.95 V from typical mobile phone battery voltages up to 5.25 V and three level translators to convert the data, RSTn and CLKn signals between a SIM card and a host microcontroller. The NVT4555 contains one voltage select pin (CTRL) to select either 1.8 V or 2.95 V for SIM card power supply and one active HIGH enable pin (EN) to enable normal operation. The NVT4555 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements. 2. Features and benefits Support SIM card supply voltages 1.8 V and 2.95 V Input voltage range to LDO: 2.5 V to 5.25 V Host microcontroller operating voltage range: 1.1 V to 3.6 V Automatic level translation of I/O, RSTn and CLKn between SIM card and host side interface with capacitance isolation Low current shutdown (EN = 0) mode < 1 A Supports clock speed beyond 5 MHz clock Incorporates shutdown feature for the SIM card signals according to ISO-7816-3 8 kV IEC61000-4-2 ESD protected on all SIM card contact pins Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green compliant) Available in 12-pin WLCSP package (1.19 mm 1.62 mm 0.56 mm (nominal), 0.4 mm pitch) 3. Applications NVT4555 can be used with a range of SIM card attached devices including: Mobile and personal phones Wireless modems SIM card terminalsNVT4555 NXP Semiconductors SIM card interface level translator and supply voltage LDO 4.
