Features

  • Supports up to 208 MHz clock rate
  • SD 3.0 specification-compliant voltage translation to support SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed and Default-Speed modes
  • Compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart Card interface requirements
  • Support SD/SIM card supply voltages with range of 1.65 V to 3.6 V
  • Host microcontroller operating voltage range: 1.08 V to 1.95 V
  • Feedback channel for clock synchronization
  • Low power consumption by push-pull output stage with break-before-make architecture
  • Automatic enable and disable through VCCB
  • 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 eliminates need for external ESD diodes
  • Level shifting buffers keep ESD stress away from the host (zero-clamping concept)
  • Available in XQFN16 with 0.4 mm pitch and WLCSP16 with 0.35 mm pitch
