Data-logging solution for portable medical, wearable and IoT devices

Cypress’ new Excelon LP Ferroelectric Random Access Memory (F-RAM) is an energy-efficient nonvolatile RAM which delivers instant-write capabilities with virtually unlimited endurance, enabling these applications to perform mission-critical data logging requirements while maximising battery life. The Excelon LP series is available in a low-pin-count, small-footprint package that is perfectly suited for space-constrained, portable applications. 

“With the rapid proliferation of portable medical devices and wearable health monitors, a premium is being placed on ultra-low-power, fail-safe storage,” said Sam Geha, Executive Vice President of the Memory Products Division at Cypress. “Our new Excelon LP F-RAMs use 200 times less energy than EEPROMs and 3,000 times less than NOR Flash, while providing virtually infinite endurance in a small form factor, making them a perfect match for these applications.”

The Excelon LP series offers 4Mb and 8Mb industrial and commercial-grade densities with 50MHz and 20MHz Serial Peripheral Interface (SPI) performance. The series reduces power consumption with 100nA hibernate and 1uA standby modes that greatly improve a battery-powered product’s user experience by extending system operating time. The Excelon family’s inherent instant writes also eliminate power failure ‘data-at-risk’ due to volatile data buffers in legacy memories. 

The family features wide voltage operation from 1.71 to 3.6V and is available in RoHS-compliant industry-standard packages that are pin compatible with EEPROMs and other nonvolatile memories. Excelon LP F-RAMs provide 1000-trillion (1015) read/write cycle endurance with ten years of data retention at 85°C or 151 years at 65°C. 

Cypress’ Excelon LP F-RAMs are currently sampling with production scheduled in the second quarter of 2019.
