512 Mbit NOR Flash in a 16-SOIC — what this part is
The memory is non-volatile and retains data across power cycles, making it suitable for code shadowing, firmware storage, and configuration data in embedded systems.
The SPI clock runs at 66 MHz. With Quad I/O, each clock cycle transfers four bits.
Active lifecycle — no EOL risk for new designs
Infineon lists the S25FL512SDPMFI013 as Active.
