Product profile 1.1 General description The IP4853CX24 is a device that fully integrates a bidirectional level shifter or voltage translator, EMI filter and ESD protection diodes. It is specifically designed to be used for memory card interfaces such as SD, microSD and MultiMediaCard (MMC) memory cards. The integrated power supply unit supplies memory cards with 2.9 V directly from the battery. This enables a 1.8 V operating host-side device (e.g. a processor interface) to communicate with a 2.9 V compliant memory card using its integrated level shifter. Radiation from digital signals in the higher harmonics, close to typical mobile phone frequencies, is suppressed by the EMI filter. The IP4853CX24 is fabricated using monolithic silicon technology in a Wafer Level Chip-Scale Package (WLCSP) with 0.4 mm pitch. 1.2 Features I I I I I I Dark Green compliant. Pb-free, RoHS compliant Integrated EMI filters Feedback channel for clock synchronization Integrated ESD protection according to IEC 61000-4-2, level 4 WLCSP with 0.4 mm pitch 1.3 Applications I SD memory card, microSD memory card and MMC interfaces in latest electronic appliances such as: N Mobile phone or smart phone N Digital camera N Card reader in (laptop) computer I Appliances requiring one or several of the following features: N Level shifting and voltage translation from 1.8 V to 2.9 V and from 2.9 V to 1.8 V N ESD protection according to IEC 61000-4-2, level 4 N Power supply regulation from battery to 2.9 V card memory voltage N EMI filtering N Integration of interface-specific biasing resistor network www.DataSheet4U.com NXP Semiconductors IP4853CX24 SD, MMC and microSD memory card integrated level shifter 2.
