Alliance Memory expands eMMC offering to simplify designs and save space
Alliance Memory has introduced 32, 64 and 128Gbyte industrial grade, embedded multimedia cards (eMMCs) for solid state storage in consumer, industrial, and networking applications.
The ASFC32G31T3-51BIN, ASFC64G31T5-51BIN and ASFC128G32T5-51BIN integrate high reliability TLC NAND flash memory with an eMMC controller and flash transition layer (FTL) management software and are supplied in a single 153 ball FBGA package measuring 11.5 x 13mm.
All of the devices are compliant with the JEDEC eMMC v5.1 industry standard and support boot operation, replay protected memory block (RPMB), device health report, field firmware updates and power-off notification. There is also 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 ASFC32G31T3-51BIN, ASFC64G31T5-51BIN, and ASFC128G32T5-51BIN are also backwards-compatible with eMMC v4.5 and v5.0.
The eMMCs are suitable for use in smart watches, tablets, digital TVs, set-top boxes, virtual reality / augmented reality (VR / AR headsets), digital cameras, CCTV, infotainment, surveillance, automation, point of sale systems, and emerging embedded applications, advised Alliance Memory.
According to the company, they can simplify designs for fast and easy system integration into products, speeding up product development and time to market. They also save space in small, space constrained products by eliminating the need for an external controller. In addition, the FTL software provides high reliability and stable performance with wear levelling and bad block management.
The ASFC32G31T3-51BIN, ASFC64G31T5-51BIN, and ASFC128G32T5-51BIN operate over an industrial temperature range of -40 to +85 degrees C and offer programmable bus widths of one, four and eight. The device’s NAND memory with internal LDO can be powered with a single 3V supply voltage, while the controller can be powered by 1.8 or 3.0V dual supply voltages.
Samples of the eMMCs are available now. Production quantities are available with lead times of eight to 10 weeks.
