Recommended usage of Microchip SPI serial SRAM devices

Keywords:serial SRAM? storage system? embedded system?

Many embedded systems require some amount of volatile storage for temporary data. This is increasingly true with Internet enabled devices. Because of their small footprint, low I/O pin requirement, low-power consumption and low cost, serial SRAMs are a popular choice for volatile storage. Microchip Technology has addressed this need by offering a line of serial SRAMs using the industry standard SPI communication. Serial SRAM devices are available in a number of density offerings, operational voltage ranges and packaging options. The serial SRAM products offer an alternative to the traditional parallel architecture that saves both board area and also I/O count on the MCU.

This application note provides assistance and guidance with the use of Microchip SPI serial SRAMs. These recommendations are not meant as requirements; however, their adoption will lead to a more robust overall design.
