What this NOR Flash brings to a BOM
The Cypress S25FL128SDPMFIG01 is a 128 Mbit NOR Flash from the FL-S family, organized as 16M x 8, with a Quad SPI interface that clocks at 66 MHz. It operates from 2.7 V to 3.6 V and is rated for the industrial temperature range of -40°C to 85°C. This part is suited for code shadowing, firmware storage, and execute-in-place (XIP) in embedded systems where non-volatile memory with fast random access is needed — typical in telecom infrastructure, factory automation controllers, and automotive cabin modules.
66 MHz Quad SPI — throughput for the bus
The Quad I/O interface clocks at 66 MHz. Designs needing faster burst reads should consider Octal SPI parts.
The FL-S series has pin-compatible density options in the same 16-SOIC footprint.
