Active 512Mbit NOR Flash for embedded code storage
The S25FS512SDSNFI010 is an active-production 512Mbit MirrorBit NOR Flash from Infineon's FS-S series, organized as 64M x 8 bits. It communicates over a SPI bus with Quad I/O and QPI protocol support, clocked at 80 MHz.
Supply and temperature envelope for BOM fit
Operating from a single 1.7 V supply, this part fits into low-voltage embedded designs without a separate regulator for the flash array. The Quad I/O interface at 80 MHz delivers a sustained read throughput that keeps a Cortex-M or RISC-V core fed from external flash without wait-state penalties at moderate clock speeds. The 512Mbit density suits firmware images with embedded file systems or over-the-air update staging areas.
Board-level integration and package handling
Supplied in tray packaging, the device is a surface-mount component. The SPI bus layout is straightforward — four signal lines plus the chip-select for a point-to-point or multi-drop topology with shared bus peripherals. The MirrorBit technology stores two bits per memory cell, doubling density without a process shrink. This part is a drop-in for existing S25FS512 footprints in the same package variant.
Lifecycle and supply posture
Infineon lists the S25FS512SDSNFI010 as Active.
