IP4853CX24 SD, MMC and microSD memory card integrated level shifter with PSU, EMI filter and ESD protection Rev. 3 — 30 September 2010 Product data sheet 1. Product profile 1.1 General description The IP4853CX24 is a device that fully integrates a bidirectional level shifter or voltage translator, ElectroMagnetic Interference (EMI) filter and ElectroStatic Discharge (ESD) protection diodes. It is specifically designed to be used for memory card interfaces such as Secure Digital (SD), microSD and Multi Media Card (MMC) memory cards. The integrated Power Supply Unit (PSU) 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-Size Package (WLCSP) with 0.4 mm pitch. 1.2 Features and benefits „ Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green 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 „ SD-memory card, microSD-memory card and MMC interfaces in latest electronic appliances such as: ‹ Mobile phone or smart phone ‹ Digital camera ‹ Card reader in (laptop) computer „ Appliances requiring one or several of the following features: ‹ Level shifting and voltage translation from 1.8 V to 2.9 V and from 2.9 V to 1.8 V ‹ ESD protection according to IEC 61000-4-2, level 4 ‹ Power supply regulation from battery to 2.9 V card memory voltage ‹ EMI filtering ‹ Integration of interface-specific biasing resistor network IP4853CX24 NXP Semiconductors SD, MMC and microSD memory card integrated level shifter 2.

Design and assembly recommendations 14.1 PCB design guidelines To achieve optimum performance it is recommended to use a Non-Solder Mask Design (NSMD) Printed-Circuit Board (PCB) design, also known as a copper-defined design, incorporating laser-drilled micro-vias connecting the ground pads to a buried ground-plane layer. This results in the lowest possible ground inductance and provides the best high frequency and ESD performance. Refer to Table 15 for the recommended PCB design parameters. Table 15.
