IP4856CX25

SD 3.0-compliant memory card integrated dual voltage level translator with EMI filter and ESD protection

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).

Not recommended for new designs (NRND).

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

Applications

  • Smartphones
  • Mobile handsets
  • Digital cameras
  • Tablet PCs
  • Laptop computers
  • SD, MMC or microSD card readers
