Product details

The Cypress S25FL204K0TMFI040 is a 4 Mbit NOR flash memory from the FL2-K series, organized as 512K x 8 bits. The 2.7 V to 3.6 V supply range and -40 to 85 °C operating temperature cover industrial control, telecom infrastructure, and outdoor equipment — anything that lives in a ventilated enclosure, not under the hood.

Package and temperature — board-fit constraints

The 8-SOIC (0.154" width, 3.90 mm body) is a standard footprint. The -40 to 85 °C rating covers factory automation and base stations.
