64 Mbit SPI NOR Flash — industrial temperature, wide-body SOIC
The Cypress S25FL064P0XMFV001 is a 64 Mbit SPI NOR Flash memory from the FL-P series, organized as 8M x 8 bits. It supports Quad I/O SPI at a clock frequency of 104 MHz, enabling fast read and program operations for firmware storage, configuration data, and code shadowing in embedded systems.
For new designs, a pin-compatible replacement within the FL-P family should be evaluated — the S25FL064P0XMFI001 is a functional equivalent with the same density, interface, and package, differing only in the temperature grade suffix.
104 MHz Quad I/O — bus margin for code execution
The 104 MHz clock rate with Quad I/O provides a sustained read throughput sufficient for execute-in-place (XIP) from the Flash, reducing the need for a separate SRAM cache in cost-sensitive designs. The write cycle time is 5 µs per word and 3 ms per page, which is typical for NOR Flash of this density. The 64 Mbit capacity (8M x 8) accommodates moderate firmware images plus a file system or calibration tables.
16-SOIC wide-body — footprint and rework considerations
The wide-body SOIC is a common footprint for serial NOR Flash, easing second-source qualification.
