That matters when the host MCU boots from external Flash or when a wireless module loads firmware over the air — the transfer completes in less time, reducing wake-up energy in battery-powered designs. The 128 Mbit density (16 MB) holds a few full firmware images plus a config partition, with room left over for a small file system. That means the manufacturer continues to produce it, and no last-time-buy or discontinuation notice is in effect. For production planning, this removes the urgency to qualify a drop-in replacement now, though it is always prudent to monitor the PCN stream for any future changes.","metaTitle":"S25FL128SDSMFBG03 128 Mbit NOR Flash, 80 MHz Quad-SPI","metaDescription":"S25FL128SDSMFBG03 128 Mbit NOR Flash from Cypress FL-S series.
