512 Mbit NOR flash with Quad SPI — throughput for code shadowing
The S25FL512SDSBHI210 is a 512 Mbit SPI NOR flash from Infineon's FL-S family, organized as 64M x 8 bits. It clocks at 80 MHz over a Quad I/O interface, delivering roughly four times the read throughput of a standard SPI device on the same clock — relevant for XiP (eXecute-in-Place) or fast code-shadowing from flash to RAM.
Package and board-fit — 24-ball BGA, 8x6 mm
Supplied in tray format, not tape-and-reel. For high-volume reflow, a tray-to-reel conversion is needed unless the CM accepts JEDEC trays in the pick-and-place feeder.
Active lifecycle — no end-of-roadmap risk for new BOMs
Infineon lists the S25FL512SDSBHI210 as Active. There is no NRND flag, no last-time-buy window, and no official successor — the FL-S series is the current mainstream NOR flash portfolio for embedded designs. For a BOM cost engineer, this means no single-source risk from pending obsolescence. The FL-S family has broad second-source overlap with other 512 Mbit Quad SPI NOR parts at the same package and voltage, though pin compatibility should be verified per candidate.
