IP4856CX25/C SD 3.0-compliant memory card integrated dual level translator with EMI filter and ESD protection Rev. 3 13 December 2019 Product data sheet 1. General description The device is an SD 3.0-compliant 6-bit bidirectional dual voltage level translator. It is designed to interface between a memory card operating at 1.8 V or 2.9 V signal levels and a host with a fixed nominal supply voltage of 1.7 V to 3.6 V. The device supports SD 3.0, SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 high-speed (50 MHz) and default-speed (25 MHz) modes. The device has an integrated voltage selectable low dropout regulator to supply the card-side I/Os, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4). 2. Features and benefits Supports up to 208 MHz clock rate Feedback channel for clock synchronization SD 3.0 specification-compliant voltage translation to support SDR104, SDR50, DDR50, SDR25, SDR12, high-speed and default-speed modes 100 mA low dropout voltage regulator to supply the card-side I/Os Low power consumption by push-pull output stage with break-before-make architecture Integrated pull-up and pull-down resistors: no external resistors required Integrated EMI filters suppress higher harmonics of digital I/Os Integrated 8 kV ESD protection according to IEC 61000-4-2, level 4 on card side Level shifting buffers keep ESD stress away from the host (zero-clamping concept) 25-ball WLCSP pitch 0.4 mm 3.
