AEC-Q100 qualification and 256 Mbit density
The S25FL256LAGMFB003 is an Infineon FL-L series SPI NOR flash qualified to AEC-Q100 Grade 2 — the -40°C to 105°C ambient range covers under-hood and cabin electronics where the silicon sees sustained thermal cycling without derating the read throughput. The 256 Mbit density organised as 32M x 8 gives the firmware map room for a bootloader, two application images for OTA fallback, and a config sector, all on a single NOR die without external paging.
Quad I/O throughput at 133 MHz
The SPI Quad I/O interface clocks at 133 MHz, delivering a sustained read throughput of 532 Mbit/s in quad-output mode — enough to feed a Cortex-M7 executing XIP without wait-state penalties on the instruction bus. The QPI protocol mode reduces the command overhead to a single byte, lowering the bus turnaround latency for random-access reads common in boot and parameter-table lookups.
