256 Mbit NOR flash for automotive ECUs
It uses a Quad-SPI (SPI - Quad I/O) interface running at 133 MHz, which gives you fast read throughput for code shadowing and over-the-air firmware updates.
133 MHz Quad-SPI — what it means for boot and update speed
At 133 MHz with Quad I/O, this part can sustain read throughputs well above 50 MB/s in continuous-read mode. That matters when you are booting a high-end MCU or SoC from external flash, or when the OTA staging area needs to be written and verified quickly. The 32M x 8 organization (256 Mbit) gives you 32 MB of storage — enough for several firmware images, calibration tables, or a small file system for logging.
It is not rated for the 125°C+ under-hood hot spots near the exhaust, but for the vast majority of automotive electronics this temperature grade is the standard fit.
