128 Mbit SPI NOR Flash for code and data storage
It communicates over a Quad I/O SPI interface at up to 80 MHz, delivering the read throughput needed for direct code execution (XIP) and firmware-over-the-air staging in embedded systems.
At 80 MHz in Quad I/O mode, the part sustains roughly 40 MB/s read throughput on a good layout. That is enough to feed a Cortex-M7 or a mid-range RISC-V core executing from Flash without a cache miss penalty on sequential code. The Quad I/O interface also cuts the signal count to six pins (four data, one clock, one chip-select), which frees up board space and simplifies routing compared to a parallel NOR or NAND interface.
125°C rating — not just another industrial part
Many serial NOR Flash parts top out at 85°C or 105°C. The 125°C rating covers under-hood automotive, downhole instrumentation, and sealed enclosures near hot power stages. If your BOM calls for 125°C operation, this part qualifies without a derating margin.
For a new design or a production BOM, this removes the single-source obsolescence risk that haunts older NOR Flash densities.
