IP4856CX25C Overview
The device is an SD 3.0-pliant 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 1.7 V to 3.6 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.
IP4856CX25C Key Features
- Supports up to 208 MHz clock rate
- Feedback channel for clock synchronization
- SD 3.0 specification-pliant voltage translation to support SDR104, SDR50
- 100 mA low dropout voltage regulator to supply the card-side I/Os
- Low power consumption by push-pull output stage with break-before-make
- 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
