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 1.2 V to 3.3 V. The device supports SD 3.0
SDR50, DDR50, SDR25, SDR12 and SD 2.0 High-Speed (50 MHz) and Default-Speed
(25 MHz) modes. The device has an integrated switchable voltage regulator to supply the
card-side I/Os, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4).
SD, MMC or microSD memory card interfaces in portable electronic applications
supporting different interface voltage modes of the SD 3.0 specification, such as mobile
and smart phone, digital camera and card reader in (laptop) computer.
