64 Mbit NOR flash with SPI Quad I/O — what it does and where it fits
The S25FL164K0XMFI010 is a 64 Mbit NOR flash from the FL1-K family, organized as 8 M x 8 bits. It communicates over SPI with Quad I/O support at 108 MHz.
Obsolete — sourcing through independent channels
This part is marked obsolete by the manufacturer. No official successor order code is listed, so a direct pin-compatible drop-in from Cypress (Infineon) is not confirmed.
108 MHz clock and Quad I/O — bus margin for the design
The 108 MHz clock rate with Quad I/O provides a sustained read throughput higher than single-bit SPI at the same frequency. The 3 ms page write time is typical for this NOR generation.
