256 Mbit NOR flash in a 16-SOIC — SPI Quad I/O at 133 MHz
The Infineon S25FL256LAGMFA003 is a 256 Mbit NOR flash memory from the FL-L series, organized as 32M x 8 bits.
That covers the passenger cabin and most under-hood locations in a vehicle, though not the engine block or exhaust-adjacent spots where Grade 0 or 1 would be required. The FL-L series is Infineon's automotive-grade NOR flash family, designed for code shadowing and data logging in ECU, ADAS, and infotainment systems.
