It communicates over a Quad I/O SPI interface at up to 80 MHz, delivering the read throughput needed for fast boot, XIP (eXecute-In-Place), and firmware shadowing in embedded systems. The 2.7 V to 3.6 V supply range and industrial temperature grade (-40 °C to 105 °C) suit it for outdoor telecom base stations, factory automation controllers, and automotive infotainment head units that must retain code and calibration data across power cycles.","metaTitle":"Cypress S25FL256SDSMFB003 256Mbit SPI NOR Flash, 80MHz","metaDescription":"Cypress S25FL256SDSMFB003 FL-S series 256Mbit SPI NOR Flash, 80MHz Quad I/O, 2.7-3.6V, -40 to 105°C, 16-SOIC.
