Product Description
The Microchip SST25PF040C-40I/SN is a split gate serial flash memory device providing 4MB storage capacity in a space-efficient 8-pin SOIC package. Designed for demanding embedded and industrial applications, it delivers high performance, reliable operation, and flexible interface options. This device operates between 2.3V and 3.6V, featuring single voltage read and write operations for easy power management in system design.
Employing proprietary CMOS SuperFlash technology, the split gate cell structure enhances endurance and data retention, making the SST25PF040C suitable for automotive, industrial, and consumer electronics. Serial interface architecture is SPI-compatible, allowing for a four-wire connection and reduced pin-count that helps conserve PCB space and lower design costs. Dual input/output (I/O) support further enables faster transfers and advanced communication capabilities.
With a maximum clock frequency of 40 MHz, this flash memory supports rapid read and write operations. The device is synchronous and supports minimum operating temperatures of -40°C and maximum up to 85°C, ensuring reliable functionality across a wide temperature range. Its surface mount design aligns with modern PCB manufacturing techniques and delivers straightforward integration into electronic circuits.
The SST25PF040C-40I/SN meets the Automotive AEC-Q100 standard, making it suitable for vehicle electronics and robust industrial applications. The architecture allows for 100,000 endurance cycles (typical) and greater than 20 years data retention, protecting vital system information over long-term use. With a cell organisation of 4M bits and number of words at 128k, it fits diverse memory requirements.
This model is ideal for applications including automotive control units, IoT devices, data loggers, navigation systems, industrial controllers, and consumer electronics. Its reliability and wide operating temperature range make it an excellent choice for harsh environments and mission-critical systems.
