AT25SF321B-SHB-T in AT25SF Flash Memory Family
The AT25SF321B-SHB-T belongs to the AT25SF family of Serial Peripheral Interface NOR Flash memory products from Renesas Electronics Corporation. These 32Mbit devices are engineered for high-performance code shadowing and data storage applications. They leverage a single power supply and support Standard SPI, Dual SPI, and Quad SPI interfaces to achieve significant throughput. These components are designed to provide a cost-effective solution for non-volatile memory requirements in space-constrained embedded systems.
Variants in This Sub-Family
Variants within the AT25SF321B series primarily differ based on their physical packaging and temperature grading. While the internal 32Mbit silicon remains consistent, options include 8-lead SOIC, 8-pad UDFN, and 8-ball WLCSP packages to accommodate different PCB density requirements. Specific part suffixes also denote tape and reel versus tube packaging, as well as industrial temperature ranges suitable for diverse environmental conditions.
