The BIWIN BWCTARV11X64G is a 64 GB embedded flash storage chip using the eMMC 5.1 interface, commonly soldered directly to a circuit board in tablets, smartphones, single-board computers, and other embedded systems. It combines NAND flash memory with a built-in controller in a 153-ball LFBGA package (11.5 × 13 mm), following industry standards for space-efficient, low-power storage. It supports JEDEC eMMC 5.1 features like HS400 high-speed mode and integrated error-correction/management functions, delivering reliable performance for boot, app, and data storage in cost-sensitive devices.
