ASFC4G31M-51BIN
Description
Alliance Memory's 4GB eMMC device (AS04FC) is a high performance embedded MMC solution designed for embedded NAND flash applications. It supports eMMC/JEDEC 5.1 industry standard and is backward compatible with eMMC 4.5 & 5.0 version.
AS04FC device contains both MLC NAND flash and eMMC controller. A single 3V supply voltage is for the NAND area (VCC) with internal regulator and Dual supply voltages 1.8V or 3V (VCCQ) for eMMC controller. Customers find it easy to use AS04FC without having to consider any changes inside device such as Flash, leading to easier & faster development of applications (fast time to market).
Alliance Memory’s featured embedded flash management software or FTL(Flash Transition Layer) of eMMC manages high reliability with noticeable Wear Leveling, Bad Block Management and strong ECC and achieves high performance.
