64 Mbit NOR Flash with Quad-SPI for automotive and industrial designs
It uses a SPI interface with Quad I/O support, clocked at 104 MHz, which gives enough read bandwidth for execute-in-place (XIP) code shadowing or fast firmware boot in automotive ECUs and industrial controllers.
This part is listed as Last Buy. That means the manufacturer has stopped taking regular orders, and the remaining stock in the channel is the final production run. If your design currently uses the S25FL064P0XMFB000, you need to secure your last-time-buy quantities or qualify a replacement before the supply dries up.
Write-cycle timing and Quad I/O for the firmware update strategy
Page program time is 3 ms typical, and word write time is 5 µs — fast enough for OTA staging if the filesystem layer handles the 4 KB sector erase granularity. If your MCU supports Quad-SPI, this part keeps the firmware load time short.
