256 Mbit NOR Flash in a 16-SOIC wide-body
The S25FL256SAGMFVR01 is a 256 Mbit NOR Flash from Infineon's FL-S series, organized as 32M x 8 bits.
Temperature grade and what it means for deployment
The 105°C ceiling gives headroom above the 85°C industrial standard — useful when the NOR Flash sits near a hot processor or power stage inside a sealed enclosure. The 133 MHz clock frequency is the maximum SPI clock rate for Quad I/O reads. At this speed, the serial interface can sustain over 60 MB/s in quad-output mode, which keeps the CPU fed during code fetch without needing a parallel NOR interface.
How it compares to the S25FL256SAGMFV001
The closest peer is the S25FL256SAGMFV001 — same 256 Mbit FL-S die, same 16-SOIC package, same 133 MHz Quad I/O interface, same -40 to +105°C temperature range. The only difference is the packaging medium: the V001 ships in a Tray, while the VR01 ships in a Tube. For a pick-and-place line, both feed from the same tape-and-reel format if ordered that way; the tube vs tray distinction matters only for manual prototyping or low-volume hand assembly.
