Microchip Technology SST39WF800A-90-4I-M2QE Flash Memory

The SST39WF800A-90-4I-M2QE is a high-performance CMOS Multi-Purpose Flash (MPF) manufactured by Microchip Technology. It is designed to offer a reliable and flexible storage solution for a wide range of applications, including embedded systems, telecommunications, digital consumer electronics, and networking devices.

This 8 Mbit flash memory device is organized as 512K x16 bits, providing a substantial amount of data storage while maintaining a compact form factor. It features a fast read access time of 90ns, which ensures quick data retrieval, enhancing the overall performance of systems it is integrated into.

The SST39WF800A-90-4I-M2QE operates on a single 3.0V to 3.6V power supply, making it an energy-efficient choice for portable and battery-operated applications. Its low power consumption does not compromise its ability to deliver high-speed read and write operations, which is essential for modern, high-performance electronic devices.

One of the key advantages of this flash memory is its support for Sector-Erase and Block-Erase functions. These features allow for flexible memory management and easier firmware updates, as specific areas of the memory can be erased and reprogrammed without affecting the entire memory array. Additionally, the device boasts an endurance of at least 100,000 erase cycles per sector, ensuring a long operational lifespan.

The SST39WF800A-90-4I-M2QE is designed for versatility and can operate over an extended temperature range of -40°C to +85°C, making it suitable for use in harsh environments. It comes in a 48-lead TSOP (Type 1) package, which is commonly used in the industry and is compatible with standard surface-mount technology (SMT) assembly processes.

Microchip Technology provides comprehensive support for their products, including detailed datasheets, programming guides, and technical support. The SST39WF800A-90-4I-M2QE is no exception, and it is backed by the quality and reliability that is synonymous with Microchip's range of memory solutions.
