The Sky High Memory S40FC004C1B2I00000 is a 4 GB eMMC 5.1 device using an MLC NAND flash array, supplied in a 153-ball VFBGA package with an 8-bit data bus. eMMC integrates the NAND array with a managed controller in one package, so the host communicates with a standard block device and the controller handles wear leveling, ECC and bad-block management. The part operates from a 3.3 V nominal supply across a 2.7 V to 3.6 V range and is rated for an industrial -40 C to +85 C temperature range.

Industrial-grade low-density eMMC is used for boot, firmware and configuration storage in embedded systems that must survive wide temperature swings: factory automation controllers, networking and telecom line cards, transportation and automotive electronics, medical instruments, smart meters and digital signage. At 4 GB the device typically holds an embedded Linux or RTOS image plus logs rather than bulk user data, and the 153-ball VFBGA is a widely used industry-standard eMMC footprint that eases second-sourcing. Buyers are industrial and embedded OEMs, module makers, and design teams seeking an alternate source for a discontinued or allocated eMMC of the same capacity and footprint.
