Product details

With 128 Mbit of non-volatile storage, this part holds 16 MB of code or data — enough for a bootloader, RTOS image, and a config file system with room to spare. The 66 MHz SPI clock, combined with Quad I/O (four data lines), delivers read throughput around 33 MB/s in fast-read mode. That bandwidth keeps the CPU fed during execute-in-place (XIP) operation without stalling on flash access.

The surface-mount package suits reflow assembly and keeps board area modest. When laying out the PCB, place the decoupling cap within 5 mm of the supply pin to keep the 66 MHz clock edge clean.

Frequently asked questions

What is the memory organization of S25FL128SDPMFIG10?

The memory is organized as 16M x 8 bits, giving a total of 128 Mbit (16 MB) of non-volatile storage.

What is the closest pin-compatible alternative to S25FL128SDPMFIG10?

Pin-compatible alternatives exist within the Infineon FL-S family at different densities (e.g., 64 Mbit or 256 Mbit) in the same 16-SOIC footprint, allowing a density upgrade without a board change.
