NXS0506 SD 3.0-compatible memory card integrated auto-direction control and level translator with EMI filter and ESD protection Rev. 1 — 31 January 2022 Product data sheet 1. General description
The NXS0506 is an SD 3.0-compatible bidirectional dual supply level translator with auto-direction control. It is designed to interface between a memory card operating at 1.7 V to 3.6 V signal levels and a host with a nominal supply voltage of 1.1 V to 1.95 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 a built-in EMI filter and robust ESD protection (IEC 61000-4-2, level 4).
2. Features and benefits
• Supports up to 208 MHz clock rate • SD 3.0 specification-compatible voltage translation to support: SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed and Default-Speed modes • 1.1 V to 1.95 V host side interface voltage support • Auto-direction sensing • Low power consumption • Integrated pull-up resistors: no external resistors required • Integrated EMI filters suppress higher harmonics of digital I/Os • Level shifting buf ers keep ESD stress away from the host (zero-clamping concept) • 16-bumps WLCSP package; pitch 0.35 mm • ESD protection: • HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2 kV • CDM ANSI/ESDA/JEDEC JS-002 Class C3 exceeds 1 kV • IEC61000-4-2, level 4, contact discharge on all memory card-side pins exceeds 8 kV • IEC61000-4-2, level 4, air discharge on all memory card-side pins exceeds 15 kV • Specified from -40 °C to +85 °C
