Product details

16 Mbit SPI Quad-I/O NOR Flash — what it delivers

The Cypress S25FL116K0XNFIQ10 is a 16 Mbit SPI NOR Flash memory from the FL1-K series, organized as 2M x 8 bits. It uses a Quad-I/O SPI interface that supports read speeds up to 108 MHz, delivering fast code shadowing and execute-in-place (XIP) performance for embedded systems.

Cypress has ended production, and the S25FL116K0XNFIQ10 is no longer available through the factory channel.

Replacement and cross-reference options

A direct pin-compatible replacement from the same Cypress FL1-K family is the S25FL116K0XNFI. The base product number S25FL116 is shared, and the 8-WSON (5x6) package footprint is identical. The key difference is the ordering code suffix — the 'Q10' version is obsolete, while the non-'Q10' suffix may still have production life depending on the specific variant. Confirm the exact suffix against your BOM's programmed firmware and the datasheet's ordering information table before committing a cross-reference.

Frequently asked questions

Is S25FL116K0XNFIQ10 equivalent to S25FL116K0XNFI?

The S25FL116K0XNFIQ10 and S25FL116K0XNFI share the same base product number (S25FL116) and the same 8-WSON (5x6) package, so they are electrically and footprint-equivalent. The suffix difference (Q10 vs. no Q10) typically indicates a factory ordering code variation — possibly related to packing, testing, or revision level. Before substituting, confirm the exact suffix matches your BOM's firmware image and check the Cypress datasheet's ordering information table for any documented differences in speed grade or temperature range.

What is a suitable replacement for S25FL116K0XNFIQ10?

The closest pin-compatible replacement is another S25FL116 variant from the same FL1-K family, such as S25FL116K0XNFI (without the Q10 suffix). Both are 16 Mbit SPI Quad-I/O NOR Flash in the 8-WSON (5x6) package. If a full cross-reference is needed, parts from the Macronix MX25L or Winbond W25Q series in the same 8-pin WSON footprint and 16 Mbit density are functional equivalents, though the exact Quad-I/O command set and status register layout should be verified against the firmware driver.
