Alliance eMMC 

• Alliance Memory industrial-grade embedded multi-media card (eMMC) solutions offers replacement for lower density 4GB and 8GB eMMC for solid-state storage in consumer, industrial, and networking applications. 

• The 4GB ASFC4G31M-51BIN and 8GB ASFC8G31M-51BIN each integrate NAND flash memory with an eMMC controller and flash transition layer (FTL) management software in a single 11.5 mm by 13 mm 153-ball FBGA package , compliant with JEDEC eMMC v5.1 industry standard supporting features such as boot operation; replay protected memory block (RPMB); device health report; field firmware updates; power off notification; enhanced strobe features for faster and more reliable operation; write leveling; high-priority interrupt (HPI); secure trim/erase; and high-speed HS200 and HS400 modes. The ASFC4G31M-51BIN and ASFC8G31M-51BIN are also backwards-compatible with eMMC v4.5 and v5.0.

• The eMMC’s will be used in products such as smart watches, tablets, digital TVs, set-top boxes, VR and AR headsets, digital cameras, infotainment, CCTV, surveillance, automation, point-of-sale systems and emerging embedded applications. For designers, the ASFC4G31M-51BIN and ASFC8G31M-51BIN simplify designs for fast and easy system integration in these products — speeding up product development and time to market — while saving space by eliminating the need for an external controller. In addition, the devices’ FTL software provides high reliability and stable performance with wear levelling and bad block management.

• The ASFC4G31M-51BIN and ASFC8G31M-51BIN operate over an industrial temperature range of -40°C to +85°C and offer programmable bus widths of x1, x4, and x8. The devices’ NAND memory with internal LDO can be powered with a single 3V supply voltage, while the controller can be powered by 1.8V or 3V dual supply voltages.
