256 Mbit NOR Flash for SPI boot — what it carries
The Infineon S25FL256LDPNFV011 is a 256 Mbit NOR Flash from the FL-L series, organized as 32M x 8. It supports SPI with Quad I/O and QPI at 66 MHz clock, with supply range 2.7 V to 3.6 V. Temperature grade is -40 °C to 105 °C, industrial-rated. That covers outdoor telecom cabinets, engine-bay controllers, and factory-floor PLCs where the ambient inside the enclosure can climb. The 8-WSON (6x8) package with exposed pad pulls heat into the board copper — useful if the part is doing sustained firmware reads in a hot environment.
No last-time-buy window, no EOL notice to track.
