256 Mbit NOR Flash in a 24-BGA — what this part is
The S25FL256SAGBHVA00: It uses a Quad-SPI (SPI - Quad I/O) interface that clocks at 133 MHz, giving the host controller fast read throughput for execute-in-place (XIP) firmware or data logging. The supply range is 2.7V to 3.6V, which maps directly to 3.3V logic systems without a level shifter.
The 105°C upper limit is the spec that keeps the BOM valid for extended-temperature environments without a separate screening step.
Quad-SPI at 133 MHz — what the clock speed buys you
133 MHz clock on the Quad I/O interface supports XIP of firmware from Flash. For a 256 Mbit density, this clock rate is typical of the FL-S series.
Package and board-level handling
24-TBGA (8x6 mm) package is a surface-mount BGA. Supplier device package code is 24-BGA (8x6).
For a BOM line, this means no imminent obsolescence risk, and the part can be qualified into a new design with confidence that supply will hold through the production run.
