The Infineon (Cypress) S25FL512SAGBHI313 is a 512 Mbit FL-S series NOR Flash memory organised as 64M x 8 bits. It communicates over a standard SPI bus with Quad I/O support, clocked at up to 133 MHz. The 2.7 V to 3.6 V supply range and -40°C to 85°C operating temperature make it a fit for industrial control, networking equipment, and embedded systems that need a large, fast code-storage or data-logging memory in a small footprint.
133 MHz Quad I/O — sustained read throughput
The 133 MHz clock rate with Quad I/O enables faster read throughput than a single-bit SPI part at the same frequency.
The base product number is S25FL512, and the FL-S series includes multiple density and package variants — useful if a design later needs a drop-in density change on the same footprint.
