The S25FL256SAGMFVG01: SPI Quad I/O interface at 133 MHz clock frequency.
Product status is Active.
It is a surface-mount gull-wing package that reflows easily with standard lead-free profiles. The 16-pin count maps to the industry-standard pinout for SPI NOR Flash, so swapping to another vendor's 16-SOIC Quad SPI part typically requires no board spin — just a firmware check on the read command set.
The two parts differ only in temperature grade. Electrically and functionally they are identical — same 256 Mbit density, same Quad SPI interface at 133 MHz, same 16-SOIC package. The VG01 suffix is the wider-temperature variant.
Yes. The memory interface is SPI with Quad I/O, which uses four data lines (IO0-IO3) for read operations. At the 133 MHz clock rate, Quad I/O delivers up to 532 Mbps read throughput — roughly 4x faster than a standard single-bit SPI read. This is the key feature that makes the part suitable for execute-in-place (XIP) from a high-speed MCU.
