Product details

The S25FL128SDPMFIG11: It communicates over an SPI bus with Quad I/O support, which lets the host read four data lines simultaneously — a practical speed-up for code shadowing or data logging without switching to a parallel interface. The 66 MHz clock rate on the Quad I/O interface delivers a sustained read throughput that keeps a Cortex-M or similar MCU fed during execute-in-place (XIP) boot, as long as the host controller supports the quad mode.

The FL-S series is a mature, widely used family, and the 128 Mbit density is a common sweet spot for firmware storage in embedded systems.

Frequently asked questions

What is the memory size and organization of S25FL128SDPMFIG11?

The memory size is 128 Mbit, organized as 16 M x 8 bits. This is a byte-wide organization typical of serial NOR Flash, where the host accesses the array through the SPI interface in 8-bit (byte) or larger bursts.
