128 Mbit NOR Flash in a 24-BGA footprint
The S25FL128LDPBHV033 is a 128 Mbit SPI NOR Flash from Infineon's FL-L series, organized as 16M x 8 bits. It communicates over a SPI bus supporting Quad I/O and QPI protocols at up to 66 MHz, giving the read throughput needed for code shadowing or data logging in embedded systems.
Industrial temperature grade and interface
The non-volatile NOR technology retains data without refresh and supports execute-in-place (XIP) for direct code execution.
Infineon lists the S25FL128LDPBHV033 as Obsolete. For new designs, consider Infineon's current FL-L or FS-series NOR Flash devices in the same 24-BGA footprint, but verify pin compatibility and software command set alignment before substituting. The base product number S25FL128 indicates the family; later revisions may offer higher speed grades or extended endurance.
