Alliance Memory expands eMMC with 5GB and 10GB 3D pSLC

Offering 30,000 program/erase cycles, the 5GB ASFC5G31P3-51BIN and 10GB ASFC10G31P3-51BIN integrate high-reliability 3D pSLC NAND flash memory with an eMMC controller and flash transition layer (FTL) management software in a single 11.5 x 13mm by 1mm 153-ball FBGA package.

The devices released are compliant with the 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 levelling, high-priority interrupt (HPI), secure trim/erase, and high-speed HS200 and HS400 modes. The ASFC5G31P3-51BIN and ASFC10G31P3-51BIN are also backwards-compatible with eMMC v4.5 and v5.0.

Featuring a 32MB boot partition, the eMMCs will be used in products such as smart watches, tablets, digital TVs, set-top boxes, VR and AR headsets, digital cameras, CCTV, infotainment, surveillance, automation, point-of-sale systems, and emerging embedded applications. For designers, the ASFC5G31P3-51BIN and ASFC10G31P3-51BIN 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 device's FTL software provides high reliability and stable performance with wear levelling and bad block management.

"With the introduction of these new enhanced-mode 3D pSLC parts, we've further solidified our position as a leading provider of eMMC technology," said David Bagby, President and CEO, Alliance Memory. "For our customers, these lower-density devices offer higher reliability and endurance than MLC and TLC NAND solutions while delivering the same ease of integration and space savings."

The ASFC5G31P3-51BIN and ASFC10G31P3-51BIN 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.

Samples of the eMMCs are available now. Production quantities are available with lead times of eight weeks.
