The 85 MHz clock frequency gives a theoretical read throughput of about 10 MB/s in quad-I/O mode, though the actual sustained rate depends on the controller's SPI peripheral and the flash's internal access latency. This is fine for firmware updates or configuration storage where writes are infrequent; it is not a candidate for high-speed data logging. The narrow 3.90 mm body width saves board space compared to wider SOIC packages.","metaTitle":"S25FL204K0TMFI043 Infineon 4Mbit SPI NOR Flash, 85MHz","metaDescription":"Infineon S25FL204K0TMFI043 4Mbit SPI NOR Flash, 85MHz, 2.7V-3.6V, 8-SOIC, -40°C to 85°C.
