Automotive NOR flash for code shadowing and data logging
It stores firmware and calibration data in an ECU, AD.
The 64M x 8 organization gives you 512 Mbit of non-volatile storage in a 24-ball BGA package that measures 8x6 mm. That is a compact footprint for a dense code store, but it is a BGA — so it needs a reflow oven and X-ray inspection. Not a field-swap part; plan for it at the PCB layout stage. The SPI Quad I/O and QPI interface let you read at higher throughput than a standard SPI part, which matters if you are executing code in place or doing over-the-air updates on a tight boot-time budget.
No end-of-life notice on the horizon, so it is safe to freeze into a production BOM.
