Microchip Technology's SST25WF020-40-4I-SAF is a 2-Mbit SPI serial Flash memory device featuring a 256K x 8 memory organization. This NOR Flash memory operates with a maximum clock frequency of 40 MHz and supports a supply voltage range of 1.65V to 1.95V, with a nominal 1.8V. The SST25WF020 series offers a data retention of 100 years and is designed for robust performance across an industrial temperature range of -40°C to +85°C. Its small outline package (PDSO8) with a 1.27mm terminal pitch facilitates surface mounting in space-constrained applications. Key features include hardware and software write protection, enabling secure data storage. This component is suitable for applications in industrial control systems, consumer electronics, and communications infrastructure where reliable non-volatile storage is critical.
