Voltage Level Translator 25-Pin WLCSP T/R

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 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).

• Supports up to 100 MHz clock rate
• Feedback channel for clock synchronization
• SD 3.0 specification-compliant voltage translation to support SDR50, DDR50, SDR25, SDR12, high-speed and default-speed modes
• 50 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
