The S25FL256SDSBHM210: It communicates over a SPI interface with Quad I/O support, clocked at 80 MHz — enough to feed a high-speed MCU or FPGA configuration bus without a separate parallel memory controller.
AEC-Q100 qualification — the sourcing gate for automotive BOMs
This part carries AEC-Q100 qualification, the automotive industry's stress-test standard for ICs.
Supply range and interface — board-level integration notes
The memory runs from a single 2.7V to 3.6V supply, which aligns with standard 3.3V logic rails used across automotive MCUs and SoCs. The SPI Quad I/O interface uses four data lines for read operations, so a 80 MHz clock delivers an effective throughput of 320 Mbps (4 bits per cycle) — enough for code shadowing or high-speed data logging without saturating the bus.
