64 Mbit NOR Flash with Quad SPI for industrial firmware storage
It communicates over a SPI interface with Quad I/O and QPI support, clocked at 108 MHz. The part operates from 2.7 V to 3.6 V and is rated for -40°C to 105°C, making it suitable for industrial control, motor drives, and outdoor telecom equipment where firmware storage must survive wide temperature swings.
108 MHz Quad SPI — what it means for read throughput
The 108 MHz clock frequency applies to the SPI interface in Quad I/O mode, where four data lines transfer simultaneously.
This part fits factory automation panels, outdoor base stations, and engine-bay-adjacent electronics that see sustained heat but not the under-hood extremes of a passenger vehicle. The 105°C ceiling means the flash retains data through a hot enclosure without derating the read current.
Housed in an 8-SOIC wide-body package (5.30 mm body width), the S25FL064LABMFV011 mounts on standard surface-mount pads. The 8-pin footprint is shared across many NOR Flash parts in this density class, so a board layout for a 64 Mbit SPI flash from another vendor often accepts this part with no spin.
