IP4855CX25 SD 3.0-compliant memory card integrated 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 1.2 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).
产品特点 Features
- 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
- 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)
- Pb-free, RoHS compliant and free of halogen and antimony (Dark Green compliant)
- 25-ball WLCSP; pitch 0.4 mm
