The Infineon S25FL116K0XNFI010 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 running at 108 MHz, which allows fast read and program operations for code shadowing, firmware storage, or data logging in embedded systems. The memory is non-volatile, retaining data without power, and supports page program with a write cycle time of 3 ms per word or page.
The S25FL116K0XNFI010 is marked obsolete by the manufacturer.
The 108 MHz clock rate with Quad I/O interface gives a theoretical peak read throughput of about 54 MB/s in quad mode. That is fast enough to support execute-in-place (XIP) from the flash for many MCUs, avoiding the need to shadow code into RAM. The 3 ms page program time is typical for NOR Flash of this density.
