The Infineon S25FL116K0XBHIS20 is a 16 Mbit serial NOR Flash memory from the FL1-K family, organized as 2 M x 8 bits. It uses a SPI interface with Quad I/O support, allowing read and program operations over four data lines at a clock frequency up to 108 MHz. This makes it suitable for code shadowing, firmware storage, and configuration data in embedded systems where a small-footprint, non-volatile memory is needed.
108 MHz Quad I/O — throughput for execute-in-place
The 108 MHz clock frequency on the Quad I/O interface delivers a theoretical read throughput of 54 MB/s, which is enough for direct code execution (XiP) from the Flash in many MCU and SoC designs. This eliminates the need to copy code to RAM at boot, saving on RAM cost and boot time. The 3 ms page write time is typical for this NOR generation — fine for over-the-air updates or configuration writes, but not for streaming data logging.
24-ball BGA — footprint and rework considerations
It is not a hand-solderable part — board assembly needs a stencil and reflow oven.
