A 133 MHz SPI clock with Quad I/O delivers read throughput in continuous-read mode. That is enough to feed a Cortex-M or RISC-V core executing directly from Flash without a wait-state penalty at moderate core speeds.
Within the Cypress FL-S family, density variants sharing the same 16-SOIC footprint and Quad SPI interface are pin-compatible. The base product number S25FL512 covers this 512 Mbit density; a lower-density sibling (e.g., 256 Mbit) or a higher-density option (1 Gbit) may serve as a drop-in replacement if the code footprint fits. Check the manufacturer's cross-reference documentation for the exact active order code.
