512 Mbit NOR Flash in a 16-SOIC wide body
The Cypress S25FL512SDPMFVG13 is a 512 Mbit serial NOR Flash memory from the FL-S family, organized as 64M x 8 bits.
Quad I/O mode lets the part shift four data bits per clock cycle instead of one. At 66 MHz that works out to roughly 33 MB/s sustained read throughput — enough to load a 512 KB firmware image in under 16 ms. If your MCU supports Quad SPI with DDR (double data rate), the effective throughput can go higher, though the S25FL512SDPMFVG13 itself is rated for single-data-rate Quad I/O. For designs that boot from external Flash, this speed class avoids the need for a separate parallel NOR or a higher-frequency Octal SPI part.
The FL-S family has broad industry adoption, so second-source options exist within the same footprint and protocol family if dual-sourcing becomes a priority. Keep an eye on PCNs for package or wafer-fab changes, but the lifecycle risk is low for current designs.
Supply range and temperature — fit for industrial and cabin
It does not reach the 125°C or 150°C required for under-hood or downhole applications — if you need that, look at the FL-S automotive-grade variants with AEC-Q100 qualification.
16-SOIC wide — footprint and storage notes
The 0.295-inch pitch matches standard SOIC-16W land patterns.
