NVT4857UK SD 3.0-SDR104 compliant integrated auto-direction control memory card voltage level translator with EMI filter and ESD protection Rev. 2 6 June 2018 Product data sheet 1. General description The device is an SD 3.0-compliant bidirectional dual voltage level translator with auto-direction control. It is designed to interface between a memory card operating at 1.8 V or 3.0 V signal levels and a host with a nominal supply voltage of 1.2 V to 1.8 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, an auto-enable/ disable function connected to the V supply pin, built-in EMI filters and robust ESD SD protections (IEC 61000-4-2, level 4). 2. Features and benefits Supports up to 208 MHz clock rate SD 3.0 specification-compliant voltage translation to support SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed and Default-Speed modes 1.2 V to 1.8 V host side interface voltage support Feedback channel for clock synchronization 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 Automatic enable and disable through V SD 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) 20-ball WLCSP pitch 0.4 mm 3.
