Automotive-grade NOR flash for code shadowing and data logging
The S25FL064LABNFB010: The 108 MHz SPI clock with Quad I/O and QPI support delivers the read bandwidth needed for execute-in-place code shadowing and fast boot sequences.
The 108 MHz clock frequency on the SPI bus, combined with Quad I/O and QPI modes, gives this part a sustained read throughput that keeps a modern automotive MCU fed during code shadowing. At 108 MHz with four data lines, the theoretical peak is over 50 MB/s — enough to load a 64 Mbit image in under 200 ms. The QPI mode reduces command overhead by using all four I/O pins for address and data, which tightens the latency on random reads. For designs already using a 3.3 V SPI flash, this part drops into the same footprint with a firmware update to enable the higher clock rate.
Package and footprint for automotive assembly
The S25FL064LABNFB010 comes in an 8-WFDFN exposed pad package, supplier device package 8-WSON measuring 5 mm by 6 mm. The tray shipping medium is standard for engineering samples and low-volume production; for high-volume reflow, the tape-and-reel variant (S25FL064LABNFB013) is the usual ordering code.
