Alliance Memory expands industrial eMMC range to 512 GB

Alliance Memory has expanded its eMMC portfolio with additional capacities reaching 512 GB, according to its 10 September product update.

The update lists new 20 GB pseudo-SLC, 64 GB, 128 GB, 256 GB and 512 GB options, including industrial-grade devices and a 64 GB automotive-grade option.

The July 2026 datasheet for the 64 GB to 512 GB industrial family specifies 3D TLC NAND, eMMC 5.1 compliance and operation from −40°C to +85°C. Each device combines flash memory with a controller and flash-management functions.

Ordering codes are ASFC64G31T5A-51BIN, ASFC128G32T5A-51BIN, ASFC256G34T5A-51BIN and ASFC512G38T5A-51BIN. All use 153-ball BGA packages with an 11.5 × 13 mm footprint. The three smaller capacities are 1.2 mm high; the 512 GB device is 1.4 mm high.

Supported functions include firmware updates, health reporting, command queuing and wear levelling. HS400 supports an interface rate of up to 400 MB/s; this is not a sustained read or write specification. HS200 and HS400 are unavailable with the I/O supply at 2.7–3.6 V, according to the datasheet.

The September update does not give capacity-specific shipment dates or endurance figures.
