New 4GB and 8GB eMMC Solutions

Alliance Memory introduces two new industrial-grade embedded multi-media card (eMMC) solutions. The 4GB ASFC4G31M-51BIN and 8GB ASFC8G31M-51BIN come with integrated NAND flash memory with an eMMC controller and flash transition layer (FTL) management software in a single 11.5mm x 13mm 153-ball FBGA package.

For designers, the devices simplify design for fast and easy system integration - speeding product development and time to market - while saving space by eliminating the need for an external controller. In addition, the FTL software provides high reliability and stable performance with wear-leveling and bad-block management.

The eMMC's are ideal for use as solid-state storage in consumer, industrial and networking applications such as smartwatches, tablets, digital TVs, set-top boxes, VR and AR headsets, digital cameras, infotainment, CCTV, surveillance, automation, point-of-sale systems and emerging embedded applications.

Key specifications and benefits:

• Complies with the JEDEC eMMC v5.1 industry standard and supports features such as:
• Boot operation
• Replay-Protected-Memory-Block (RPMB)
• Device status reporting
• On-site firmware updates
• Power off notification
• Improved strobe functions for faster and more reliable operation
• Write leveling
• High-Priority Interrupt (HPI)
• Safe trim/erase
• High-speed HS200 and HS400 modes
• Backward compatible with eMMC v4.5 and v5.0
• Operates over an industrial temperature range of -40°C to +85°C
• Offers programmable bus widths of x1, x4 and x8
• NAND memory with internal LDO can operate from a single 3 V supply voltage
• The controller can be operated with a dual supply voltage of 1.8 V or 3 V

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