Product details

Quad SPI at 133 MHz gives a theoretical read throughput of 532 Mbps (133 MHz × 4 I/O). For a typical automotive MCU booting from external Flash, this means the code shadowing from the NOR to internal SRAM completes in under a second for a 2 MB image. The interface supports XIP (execute-in-place) for latency-sensitive look-up tables or calibration data that stays in Flash.

For a buyer qualifying a BOM for a multi-year automotive program, this means no last-time-buy exposure on the current forecast horizon.

Frequently asked questions

Is S25FL256SAGNFB000 a direct replacement for S25FL256SAGBHI000?

The S25FL256SAGBHI000 is a sibling in the same 256 Mbit FL-S family, but the suffix differences indicate variations in package or temperature grade.

Does S25FL256SAGNFB000 support Quad SPI?

Yes, the memory interface is SPI - Quad I/O, supporting standard SPI, Dual I/O, and Quad I/O operations at up to 133 MHz.
