Alliance Memory 4GB and 8GB eMMC solutions simplify designs


KIRKLAND, Wash., Jan. 31, 2022 (GLOBE NEWSWIRE) — Alliance Memory today introduced two new industrial-grade embedded media card (eMMC) solutions. 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 storage management software. the flash transition layer (FTL) in a single 11.5 mm by 13 mm FBGA package of 153 beads.

The devices released today are compliant with the JEDEC eMMC v5.1 industry standard, supporting features such as boot operation, replay protected memory block (RPMB), device, field firmware updates, power off notification, enhanced strobe features for faster and faster operation. more reliable operation, write leveling, high priority interrupt (HPI), secure adjust/erase, and high-speed HS200 and HS400 modes. The ASFC4G31M-51BIN and ASFC8G31M-51BIN are also backward compatible with eMMC v4.5 and v5.0.

eMMCs will be used in products such as smartwatches, tablets, digital TVs, set-top boxes, VR and AR headsets, digital cameras, infotainment, CCTV, surveillance, automation, systems point of sale and emerging in-vehicle applications. For designers, the ASFC4G31M-51BIN and ASFC8G31M-51BIN simplify designs for quick and easy system integration into these products – accelerating product development and time to market – while saving space eliminating the need for an external controller. In addition, the devices’ FTL software provides high reliability and stable performance with wear leveling 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 NAND memory of devices with internal LDO can be powered with a single 3V supply voltage, while the controller can be powered by dual 1.8V or 3V supply voltages.

Samples and production quantities of the eMMCs will be available in the first quarter of 2022, with lead times of 12 weeks.
