64 Mbit NOR Flash in a 24-BGA — what the FL1-K brings
The S25FL164K0XBHI033: This is the density tier that fits firmware storage for a medium-complexity MCU or FPGA configuration image, where the Quad I/O gives a read throughput edge over standard SPI without moving to a parallel NOR or NAND.
108 MHz Quad I/O — bus margin for execute-in-place
For a design that maps the flash into the CPU address space for execute-in-place (XIP), this keeps the instruction fetch pipeline fed without wait-state penalties that slower serial flashes introduce. The 3 ms page write time is typical for this NOR generation — adequate for OTA update staging but not for high-frequency logging.
The 24-TBGA package measures 6×8 mm.
Infineon has discontinued this specific variant, so it is no longer available through the factory on a standard production schedule.
