Product details

256 Mbit NOR Flash with Quad SPI for code-shadow and data-logging

The S25FL256LDPNFN011 is a 256 Mbit NOR Flash from Infineon's FL-L series, organized as 32M x 8 bits. It uses the SPI - Quad I/O and QPI interface, clocking at 66 MHz for fast read throughput — useful for code shadowing in embedded systems or storing configuration data that needs quick random access.

The 8-pin footprint keeps the layout simple, and the SPI bus lines (CS, CLK, MOSI, MISO) route easily on a two-layer board.

Active lifecycle and sourcing

Infineon lists this part as Active (current production).

Frequently asked questions

What is the memory interface and clock speed of S25FL256LDPNFN011?

It uses a SPI - Quad I/O and QPI interface with a 66 MHz clock frequency. The Quad I/O mode reads four bits per clock cycle, giving an effective throughput of 264 Mbps — enough for fast code shadowing or firmware updates.
