SiliconGo e•MMC is an embedded storage solution designed in a BGA package form. The operation of e•MMC is a simple
read and write to memory using e•MMC protocol v5.1 which is an industry standard.
The e•MMC consists of NAND flash and a MMC controller. 3.3V supply voltage is required for the NAND area (V CC ) ，
whereas 1.8V or 3.3V dual supply voltage (V CC or V CCQ ) is supported for MMC controller.
There are several advantages of e•MMC. It is easy to be used on the standard interface, which allows the easy and widely
used integration with general CPU. Any revision or amendment of NAND is invisible to the host as the embedded e•MMC
controller insulates NAND technology from the host. It means that the host can support the newest processing flash without
updating its hardware or software.
SiliconGo e•MMC has high performance at a competitive-cost, high quality and low power consumption. e•MMC provides
capacities from 4GB to 64GB.
