The Infineon (formerly Cypress) S25FL116K0XBHI020 is a 16 Mbit SPI NOR flash memory organized as 2M x 8 bits, part of the FL1-K series. It communicates over a Quad I/O SPI interface at up to 108 MHz, which gives it enough read bandwidth to support execute-in-place (XIP) from a microcontroller or FPGA configuration storage.
Sourcing when the factory line has moved on
If your BOM still calls out this exact order code, the lead time and price will depend entirely on what stock remains in distribution or on the spot market — there is no factory LTB window left to book.
The mounting is surface mount only.
That is fast enough to shadow a firmware image into RAM on power-up without stalling the host processor, or to stream configuration data to an FPGA from a single serial flash. The write cycle time is a standard 3 ms per page or word — typical for NOR flash of this density — so the speed advantage is on the read side, not the program/erase path.
