SFEM4096B1EA1TO-I-GE-121-STD

• 32Gb MLC NAND Flash Density
• E-MMC Managed NAND Interface with Integrated Controller
• 3.3V Supply Operation
• Selectable 1-bit, 4-Bit and 8-Bit Bus Width
• 153-Ball BGA Package

The SFEM4096B1EA1TO-I-GE-121-STD is a Swissbit AG managed NAND flash device using MLC NAND with an e-MMC interface, rated at 32Gb and operating from a 3.3V supply. It is supplied in a 153-ball BGA package and supports 1-bit, 4-bit and 8-bit bus configurations. Managed NAND integrates the flash array with its own controller, so the host addresses a block storage device rather than raw NAND. Note that the catalogue record for the SFEM4096B1EA1TO-I-GE-121-STD carries only a customs classification and no technical attributes.

e-MMC devices give a system soldered-down block storage without requiring the host to implement a flash translation layer, since wear levelling, error correction and bad-block management run on the on-package controller. Swissbit positions its storage for industrial and long-lifecycle applications, so parts in this family are typically found in industrial gateways and controllers, networking and transport equipment, medical devices, and embedded systems that need controlled bill-of-materials longevity rather than the shortest consumer product cycle. A soldered BGA is also more shock- and vibration-tolerant than a removable card. Buyers are typically industrial and embedded OEMs specifying storage with supply continuity commitments.
