The Cypress S25FL116K0XMFIQ13 is a 16 Mbit SPI NOR flash memory from the FL1-K series, organized as 2M x 8 bits. It communicates over a Quad I/O SPI interface at up to 108 MHz, which gives it enough read throughput for execute-in-place (XIP) boot code or fast firmware shadowing into RAM. The 2.7V to 3.6V supply range ties directly to 3.3V logic rails common on MCUs and SoCs. Industrial temperature grade (-40°C to 85°C) suits outdoor telecom, factory automation, and embedded control boards — not extended automotive under-hood use. The 8-SOIC package is a standard footprint, easy to route and rework.
This part is marked obsolete by Cypress (now Infineon). If you are planning a new design, avoid this part and select an active-series equivalent.
