Product details

Quad I/O means the four data lines each carry a quarter of the payload per clock edge, so at 133 MHz the raw bit rate hits 532 Mbps (four bits per cycle). That is enough to feed a Cortex-M7 or RISC-V core running from external flash without stalling on instruction fetches, as long as the controller's Quad SPI peripheral can keep up. The 133 MHz rating is the maximum clock; real throughput depends on the controller's own timing and the board's signal integrity on the four data traces.

24-BGA footprint — layout and rework notes

The 24-ball BGA measures 8 mm x 6 mm (supplier device package 24-BGA). That is a fine-pitch array — the balls are small enough that a hand-solder rework station with a hot-air nozzle and stencil is the practical repair method.

New designs can commit this part without worrying about a forced migration mid-production.

Frequently asked questions

Does S25FL128SAGBHVA03 support Quad SPI operation?

Yes, the memory interface is SPI Quad I/O, meaning it can transfer four bits per clock cycle on the four data lines. At 133 MHz that gives a raw read throughput of 532 Mbps, suitable for code shadowing and XIP.

Can S25FL128SAGBHVA03 replace S25FL128SAGBHI03?

The S25FL128SAGBHI03 is a different ordering code variant in the same FL-S family. The suffix difference typically indicates package or temperature grade variation. Without the full datasheet cross-reference, confirm the package code and temperature range match your board's footprint and environment before substituting.

What is the difference between NOR and NAND flash?

NOR Flash (like this part) provides random-access read with fast boot and XIP capability, but lower density per die area compared to NAND. NAND offers higher density and lower cost per bit but requires a controller for block management and has slower random access. NOR is the choice for code storage where the CPU executes directly; NAND is for bulk data and file systems.
