256 Mbit automotive NOR flash with Quad SPI
At 133 MHz with Quad I/O, the S25FL256LAGBHM020 delivers a sustained read throughput that can feed an execute-in-place (XIP) firmware image without the MCU waiting for a slower serial flash. The QPI mode reduces the command overhead by operating the full interface in quad width, which matters when the MCU's SPI controller supports it. If your design is currently using a single- or dual-SPI NOR flash at a lower clock, this part buys you a faster boot and tighter real-time loop.
The part comes in a 24-ball TBGA package measuring 8 mm x 6 mm (24-BGA). It is a surface-mount device.
