In addition to its fast write capabilities, FRAM is also ideal for applications that use multiple sensors. For these applications, the ability to continuously write a maximum amount of data is critical. In today’s applications, the write endurance of MCUs limit engineers to about 10,000 write cycles when designing with flash after which the memory becomes unreliable and therefore causes device failure. If an engineer needs more reliability and the ability to capture significantly more data than current flash MCUs can provide, they must look at adding expensive components and size to their system. With low power FRAM MCUs from TI, developers can pull this into one single chip solution that offers more than 100 trillion write cycles. The limitations previously presented by embedded flash are no longer a design obstacle. To put this into perspective, in a real application requiring continuous data logging, FRAM supports over 150,000 years of continuous data logging at 13 kBps versus less than seven minutes with conventional flash.
