NVT4555UK - SIM card interface level translator and supply voltage LDO - I²C电压转换器 - I²C - 恩智浦, LLC
The NVT4555 device is built for interfacing a SIM card with a single low-voltage host sideinterface. The NVT4555 contains an LDO that can deliver two different voltages, 1.8?V or2.95?V from typical mobile phone battery voltages up to 5.25?V and three level translatorsto convert the data, RSTn and CLKn signals between a SIM card and a hostmicrocontroller.
The NVT4555 contains one voltage select pin (CTRL) to select either 1.8?V or 2.95?V forSIM 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 cardinterface requirements.
- 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 μA
- 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 x 1.62?mm x 0.56?mm (nominal), 0.4?mm pitch)
- NVT4555 can be used with a range of SIM card attached devices including:
- Mobile and personal phones
- Wireless modems
- SIM card terminals
