Product details

256 Mbit NOR Flash in an 8-WSON — what the package and speed mean on the board

The Infineon S25FL256SAGNFI003 is a 256 Mbit FL-S series NOR Flash memory in an 8-WDFN exposed-pad package. It uses a Quad-SPI interface clocked at 133 MHz, organised as 32M x 8 bits.

133 MHz Quad-SPI — what it means for boot and code shadowing

8-WSON exposed pad — footprint and rework notes

The FL-S series is a mature, widely used NOR flash family, and the 256 Mbit density is a common capacity point that tends to stay in production longer than the high-density or niche variants.

Frequently asked questions

Is S25FL256SAGNFI003 compatible with a 3.3 V supply?

No level shifting needed on the SPI lines if the host controller also runs at 3.3 V.
