Hwaling Technology Co., Ltd.



Product Name : 32Gb eMMC

Item No. : HAA2BG17111S


AXEME eMMC is an embedded MMC solution designed in a BGA package form. eMMC operation is identical to a MMC device and therefore is a sim- ple read and write to memory using MMC protocol v5.1 which is a industry standard.

eMMC consists of NAND flash and a MMC controller. 3V supply voltage is required for the NAND area (VCC) whereas 1.8V or 3V dual supply voltage (VCCQ) is supported for the MMC controller. AXEME eMMC supports HS400 in order to improve sequential bandwidth, especially sequential read performance.

There are several advantages of using eMMC. It is easy to use as the MMC interface allows easy integration with any microprocessor with MMC host. Any revision or amendment of NAND is invisible to the host as the embedded MMC controller insulates NAND technology from the host. This leads to faster product development as well as faster times to market.

The embedded flash management software or FTL(Flash Transition Layer) of eMMC manages Wear Leveling, Bad Block Management and ECC. The FTL supports all features of the Axeme NAND flash and achieves optimal performance.
