AT25SF081-SSHD-T – ATMEL

The AT25SF081-SSHD-T is an 8-Megabit (1024K x 8) Serial Peripheral Interface (SPI) Flash memory device fabricated by ATMEL. It operates from a supply voltage of 1.65V to 1.95V. The device supports standard SPI, Dual SPI, and Quad SPI operation, maximizing read throughput. The SPI clock frequency can reach up to 80 MHz in Fast Read Dual/Quad I/O instructions. The memory array is organized into 4096 pages of 256 bytes each. It is housed in an 8-lead Small Outline Integrated Circuit (SOIC) package with a standard footprint. The “SSHD” designation likely indicates a specific speed grade, temperature range, and packaging variation within the AT25SF081 family, with “T” denoting tape and reel packaging for automated assembly. The device features a software write protection mechanism and supports JEDEC standard Serial Flash Discoverable Parameters (SFDP).
