256 Mbit NOR flash with Quad SPI — what it fits
The part is supplied in a 16-SOIC package (0.295" body width, 7.50 mm) for surface-mount assembly. It operates from a 2.7 V to 3.6 V supply and is rated across the industrial temperature range of -40°C to 105°C.
80 MHz Quad SPI — throughput for XIP and fast boot
For designs that need to store a bootloader or real-time code and run it directly from flash, this part avoids the latency of a DRAM shadow copy. The Quad I/O also keeps the pin count low — four data lines plus clock and chip select — which simplifies routing on dense PCBs.
Industrial temperature grade — where it goes
The 105°C ceiling covers most industrial and many automotive cabin applications without requiring a separate high-temperature derating step.
Package and mounting — 16-SOIC footprint
The 16-SOIC package has a 7.50 mm body width. Verify the land pattern matches before layout.
