MMC/SD Card for Mobile Phone

 MMC (Multimedia Card) / SD (Secure Digital Memory Card) are both memory cards for multimedia data storage. SD card development is based on the MMC card technology. Comparing with MMC card, SD card is with larger memory size, higher transferring speed, but is thicker in geometry. Therefore, generally MMC card can be placed into the SD card slot, but SD card cannot be put into the MMC card slot.

When performing MMC/SD card data transferring would also be affected by the RF communication signal (800MHz ~ 2GHz), which would lead to the result of data error. AMC provide 1 EMI/ESD part in DFN tiny package for solving this issue of mobile phone application.
