256 Mbit NOR flash for automotive code and data storage
The Infineon S25FL256SDSMFB010 is a 256 Mbit NOR flash memory from the FL-S series, organized as 32M x 8 bits and accessed over an SPI Quad I/O interface at up to 80 MHz. AEC-Q100 qualification means this part is released for automotive-grade applications, with the reliability screening and PPAP documentation that Tier-1 and OEM programs require. The -40°C to +105°C operating temperature range covers under-hood and cabin environments — an engine ECU or transmission controller that sees 105°C on a hot day still has margin before the silicon hits its rated ceiling.
Interface, supply, and package fit
The SPI Quad I/O interface reads four bits per clock cycle, lifting the effective throughput above standard SPI without adding pins — useful for code shadowing or fast boot in an automotive MCU system. Supply range is 2.7 V to 3.6 V, which aligns with the 3.3 V rail common in automotive power trees; no extra regulator is needed if the bus voltage stays within that window. Housed in a 16-SOIC wide-body package (7.50 mm width), the footprint matches many existing NOR flash layouts in automotive modules — a drop-in replacement candidate if the pinout and supply are compatible.
