It uses a standard SPI serial interface and is rated for a 104 MHz clock. This class of SPI NOR Flash is commonly used for code storage, firmware shadowing, and configuration data in embedded systems — microcontrollers, FPGAs, DSPs, and SoCs that boot from serial flash.
104 MHz SPI — read throughput and bus margin
The 104 MHz SPI clock rate is the maximum read clock for this device. At that speed, the serial interface delivers roughly 13 MB/s in single-SPI mode (one data bit per clock). For a system that executes code directly from the flash (XIP), the clock speed sets the instruction-fetch bandwidth. The 104 MHz ceiling is competitive with other SPI NOR Flash parts of this generation, but note that this part does not support dual/quad SPI modes — it is a single-SPI-only device, so the read throughput is limited to one bit per cycle. If your design requires faster read-back for code shadowing or over-the-air updates, a quad-SPI or dual-SPI part would be a better fit.
That means Infineon/Cypress has stopped production and no further factory orders are being accepted. The only supply channel is the surplus and independent distribution market — broker stock, factory overruns, and date-code-located inventory. There is no official successor or recommended replacement recorded in the available lifecycle data. For a production BOM, this part carries last-time-buy risk: once the remaining distributor and broker stock is consumed, no new units will be available. If you need a pin-compatible alternative, look at the broader FL-P series or the S25FL128S family (which adds quad-SPI support), but confirm the exact footprint and command set before swapping.
The device is supplied in a 16-lead SOIC package with a 7.50 mm body width (the 0.295" wide-body variant). It is a surface-mount part, intended for reflow soldering. The shipping medium is Tray. For PCB layout, the footprint follows the standard JEDEC MS-013 variation for wide-body SOIC-16. No thermal pad or exposed paddle — the package is a standard plastic SOIC with leads on a 1.27 mm pitch.
