That is enough to feed a 32-bit MCU booting from flash without stalling on the memory interface. For a typical 1 MB firmware image, the transfer completes in about 30 ms. The QPI mode reduces the command overhead by using the same four lines for address and data, which helps when the bus is shared with other SPI slaves. The 16-SOIC package (7.50 mm body width, 0.295 inch) is a wide-body SOIC, not the narrower 3.90 mm version. The part is surface-mount only.","metaTitle":"S25FL256LDPMFI001 256Mbit SPI NOR Flash, 66MHz Quad I/O","metaDescription":"Cypress S25FL256LDPMFI001 256Mbit SPI NOR Flash, 66MHz Quad I/O, 2.7V-3.6V, -40°C to 85°C, 16-SOIC.

The key difference is the clock frequency: the 'L' variant (this part) runs at 66 MHz, while the 'S' variant is typically rated for a higher speed (often 104 MHz or 133 MHz, depending on the specific suffix). The package, pinout, and command set are otherwise identical, so the 'S' variant is a drop-in upgrade for designs that need faster read throughput. The 'L' variant is the cost-optimized choice for 66 MHz bus designs."},{"question":"Is S25FL256LDPMFI001 compatible with 3.3V systems?","answer":"It is fully compatible with 3.3 V MCUs, SoCs, and FPGAs that have SPI or Quad SPI interfaces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL256LDPMFI001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL256LDPMFI001 when reusing this data.
