AT25SF321B-SSHB-B in Renesas AT25SF/FF Serial Flash Family
The AT25SF321B-SSHB-B is a high-performance 32-Mbit Serial Peripheral Interface (SPI) NOR Flash memory component manufactured by Renesas Electronics. Designed for efficiency and reliability, this memory device supports Standard SPI, Dual SPI, and Quad SPI operation modes. It is primarily utilized in embedded systems for storing executable code, non-volatile application data, and firmware updates, offering a balanced combination of high-speed data throughput and low power consumption suitable for modern microcontroller-based architectures.
Variants in This Sub-Family
Variants within the AT25SF/FF family differ primarily in density, ranging from 4Mbit to 128Mbit, and package types such as 8-lead SOIC, UDFN, or TSSOP. The AT25SF321B specifically denotes the 32Mbit generation 'B' revision, which often features improved clock speeds and lower power profiles compared to original 'A' series parts. Packaging codes like SSHB-B indicate lead-free 150-mil SOIC8 shipping in bulk or tubes.
