512 Mbit NOR Flash for automotive code storage
The SPI Quad I/O interface at 133 MHz clock frequency provides the read bandwidth needed for fast boot and over-the-air update cycles.
AEC-Q100 and the 105°C ceiling
The 105°C operating temperature is the key differentiator from the industrial-grade siblings (S25FL512SAGMFIG10 and S25FL512SAGMFIR10, both rated to 85°C). If your BOM targets an engine bay or transmission ECU, the 105°C grade is the one to lock in; the 85°C parts are fine for cabin-domain modules.
