For a 256 Mbit device, that translates to read throughput well above 50 MB/s in fast-read mode. If your MCU boots from this Flash or you stream large look-up tables, the Quad I/O interface cuts the time the bus is busy, freeing the host for other tasks. The 133 MHz clock is the rated maximum; your host SPI controller must support that speed to get the full bandwidth. ## 16-SOIC wide-body — rework-friendly footprint The 16-SOIC (0.295\", 7.50 mm width) package is a standard wide-body SOIC. The leads are visible and accessible, so hand rework with a hot-air station is straightforward — no underfill, no hidden balls. The 1.27 mm pitch gives good clearance for routing and probing. The FL-S series is a mature, widely used NOR Flash family, and the active status reflects continued manufacturing support.","metaTitle":"S25FL256SAGMFVG03 NOR Flash 256 Mbit, 133 MHz Quad SPI","metaDescription":"S25FL256SAGMFVG03 256 Mbit NOR Flash from Cypress FL-S series. 133 MHz Quad I/O SPI, 2.7-3.6 V, -40 to 105°C.
