SDINBDG4-64G-XI1

• 64GB Managed NAND (eMMC) Storage
• eMMC 5.1 Interface
• 3.3V Operating Voltage
• -40C to +85C Operating Temperature Range
• Western Digital iNAND 7250, Industrial Series
• Integrated Controller Handling Wear leveling, ECC, and Bad-Block Management

The Western Digital SDINBDG4-64G-XI1 is a 64GB embedded Multi Media Card (eMMC) 5.1 device from the iNAND 7250 series. eMMC integrates the NAND array with its controller in a single package, so the host addresses it as a block storage device while wear leveling, ECC, and bad-block management are handled internally. This part belongs to the industrial series, runs from a 3.3V supply, and is rated from -40C to +85C.

Industrial-grade eMMC is the primary boot and application storage in equipment that runs unattended for years across a wide temperature range: industrial PCs and automation controllers, networking and telecom line cards, digital signage and kiosks, medical devices, point-of-sale terminals, and IoT gateways. It is chosen over a removable card because a soldered device removes the connector as a mechanical failure point and removes the risk of the card being pulled. Buyers are typically industrial and networking OEMs, embedded system-on-module vendors, and EMS providers sourcing qualified storage for long-lifecycle builds.
