256 Mbit NOR Flash with Quad-SPI at 133 MHz
It communicates over a SPI interface with Quad I/O support, clocked at up to 133 MHz. It comes in a 24-ball TBGA package measuring 8x6 mm, surface-mount. This is a non-volatile memory device intended for code shadowing, data logging, and firmware storage in embedded systems, networking gear, and industrial controllers.
133 MHz Quad-SPI — throughput for code shadowing
That is enough to support execute-in-place (XIP) from the Flash for many MCUs and SoCs without a separate RAM cache for critical routines. In practice, the controller's own SPI peripheral speed and the board's signal integrity on the 24-BGA package will set the real margin. Keep the Quad-SPI traces length-matched and avoid vias on the data lines to preserve the setup/hold window at this frequency.
Industrial temperature range — outdoor and factory-floor fit
The 2.7V to 3.6V supply covers both 3.3V nominal rails and the low end during battery-backed or cold-crank conditions. If your design lives in a heated indoor rack, the commercial-temperature sibling would save cost, but for any environment that sees frost or a hot enclosure, this grade is the right call.
