Overview

The device is an SD 3.0-compliant bidirectional dual voltage level translator with auto-direction control. It is designed to interface between a memory or SIM card operating between 1.62 V to 3.6 V signal levels and a host with a supply voltage of 1.08 V to 1.98 V.

  • 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 ISO-7816 SIM/Smart Card interface requirements
  • Support SD/SIM card supply voltages with range of 1.62 V to 3.6 V
  • Host microcontroller operating voltage range: 1.08 V to 1.98 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
  • Integrated EMI filters suppress higher harmonics of digital I/Os
