Need more RAM?
Serial SRAM
Serial SRAM is a standalone volatile memory that offers designers an easy and inexpensive way to add more RAM to their application. These 8-pin low power, high performance SRAM devices have unlimited endurance and zero write times, making them ideal for applications involving continuous data transfer, buffering, data logging, audio, video, internet, graphics, and other math and data-intensive functions. These devices are available from 64Kbit up to 1Mbit in density and support SPI, SDI and SQI bus modes.
Serial NVSRAM
Serial NVSRAM offers non-volatile RAM storage and is ideal for applications that need to write very often to the memory. This device is significantly lower cost than other non-volatile RAM devices and the data is backed using an external battery. This 8-pin, SPI device supports unlimited instantaneous writes to the memory array, making it ideal in applications such as meters, data loggers, data recorders, black boxes. These devices are available in 512Kbits and 1Mbit densities.
