64Mbit NOR Flash with Quad I/O
The S25FL164K0XMFIQ10 uses a Quad I/O interface with a 108 MHz clock frequency for higher read throughput than standard SPI.
The device operates from 2.7V to 3.6V supply, which aligns with common 3.3V logic rails used on Cortex-M MCUs and FPGAs.
8-SOIC package and write timing
Housed in an 8-SOIC package (0.209-inch body width, 5.30 mm), the footprint is a standard SOIC-8 wide-body that routes easily on a two-layer board. Page and word write cycles complete in 3 ms typical, which sets the programming latency for firmware updates or data logging — budget this time in the system scheduler.
