128 Mbit NOR Flash for automotive and industrial code storage
It uses a Quad SPI (Quad I/O and QPI) interface running at 133 MHz, which gives fast read throughput for code shadowing or over-the-air update staging. Organized as 16M x 8 bits, it operates from a 2.7 V to 3.6 V supply and is rated over the -40°C to 85°C temperature range — suitable for engine-bay-adjacent or cabin electronics. The 8-SOIC (0.209", 5.30 mm width) surface-mount package fits standard PCB layouts for motor drives, battery management, or telematics control units.
The 133 MHz SPI clock rate with Quad I/O support provides sustained read throughput. This clock speed reduces wait states and improves boot time for XIP execution.
AEC-Q100 and industrial temperature range
For designs that need a single NOR Flash across both automotive and industrial BOMs, this part avoids a qualification gap.
The base product number is S25FL128, so any variant-specific differences (package, temperature grade) are captured in the suffix — verify the suffix matches your BOM line before ordering.
