SD/MMC interface

This paragraph describes the Card Reader JEDED/MMC standard version 5.0 compliant.
The filter used is EMIF06-MSD02N16 by STMicroelectronics.
The SD/MMC Card Reader needs to use a power switch to limit the output current to a safe level in case the
output load exceeds the current limits threshold or a short is present.
Use an STMPS2151MTR by STMicroelectronics.
The figure below shows the SD/MMC Card Reader diagram.
The following table describes all hardware of the SD/MMC interface of the mini module and their position on PCB.
