128 Mbit NOR flash for code shadowing and data logging
The S25FL128SDSMFV000: It uses the SPI Quad I/O interface, which lets it transfer data four bits per clock cycle instead of one — so the 80 MHz clock delivers an effective read throughput well above what a standard SPI bus can manage at the same frequency. NOR flash is the go-to choice for execute-in-place (XIP) firmware storage because it offers random-access read times fast enough to run code directly, without copying it to RAM first. The 80 MHz Quad SPI interface on this part makes XIP practical for many embedded applications.
It is easy to hand-solder for prototypes and rework-friendly with a hot-air station — no BGA underfill or X-ray inspection needed.
