512Mbit NOR Flash with automotive temp range
The S25FL512SDSMFM013 is a 512Mbit NOR Flash from Infineon's FL-S series, organized as 64M x 8 bits. It communicates over an SPI Quad I/O interface at up to 80 MHz, providing fast read and program throughput for code-shadowing and data-logging tasks. The wide temperature band suits under-hood or engine-bay ECUs where the silicon sees sustained 105°C plus margin, and the 125°C ceiling covers hot-soak conditions after shutdown.
Package and supply integration
Housed in a 16-SOIC wide-body package (7.50 mm body width), the S25FL512SDSMFM013 mounts on the PCB with a standard 1.27 mm pitch footprint. The SPI Quad I/O interface reduces pin count compared to a parallel NOR bus, keeping the board layout simpler while still delivering four-bit-per-cycle read throughput. At 80 MHz in quad mode, the sustained read rate reaches roughly 40 MB/s before protocol overhead.
Infineon lists this part as Active. The base part number S25FL512 covers the family; the full suffix encodes the package, temperature grade, and tape-and-reel delivery.
