W25X40CL in Winbond W25Q SPI NOR Flash Family
The W25X40CL is a 4 Megabit Serial Flash memory sub-family manufactured by Winbond, designed to provide a storage solution for systems with limited space, pins, and power requirements. Operating on a single 2.3V to 3.6V supply, this family utilizes the SPI interface to support high-performance Dual SPI operations. It is widely recognized as a cost-effective standard for non-volatile storage in consumer electronics and industrial embedded systems requiring reliable code execution and data logging.
Variants in This Sub-Family
Variants within the W25X40CL sub-family are primarily distinguished by their physical packaging and temperature ratings. Common options include the 8-pin SOIC in 150-mil or 208-mil widths, as well as space-saving 8-pad USON and WSON packages. Standard industrial parts support a temperature range of -40°C to +85°C, while specific AEC-Q100 qualified versions may be available for automotive environments requiring higher thermal tolerance.
