The Cypress S25FL132K0XNFI010 is a 32 Mbit NOR Flash from the FL1-K series, organized as 4M x 8 bits, with a SPI Quad I/O interface clocked at 108 MHz. This density suits firmware storage for medium-complexity embedded systems — think motor drives, HMI panels, or industrial controllers that need a few MB of code space plus a parameter block. The Quad I/O interface delivers higher read throughput than standard SPI, useful for execute-in-place or fast code shadowing to RAM on boot. Supply range is 2.7 V to 3.6 V, and the operating temperature covers -40°C to 85°C, so it fits outdoor telecom cabinets or factory-floor enclosures without a heater.
