The new Excelon LP Ferroelectric Random Access Memory (F-RAM), says the company, enables fail-safe storage of mission-critical user data and maximizes battery life. It is offered as being ideal for the latest-generation portable medical and wearable devices and other IoT applications that demand nonvolatile memories to continuously log an increasing amount of user and sensor data while using as little power as possible.

The solution, says the company, is the industry’s most energy-efficient nonvolatile RAM, and delivers instant-write capabilities with virtually unlimited endurance.

“With the rapid proliferation of portable medical devices and wearable health monitors, a premium is being placed on ultra-low-power, fail-safe storage,” says 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.”

Available in a low-pin-count, small-footprint package suited for space-constrained, portable applications, the Excelon LP series offers 4MB and 8MB industrial and commercial-grade densities with 50 MHz and 20 MHz Serial Peripheral Interface (SPI) performance. Voltage operation is from 1.71 V to 3.6 V, and power consumption is 100 nA in hibernate mode and 1 uA in standby mode.

The family’s inherent instant write capability also eliminates power failure “data-at-risk” due to volatile data buffers in legacy memories. Excelon LP F-RAMs provide 1000-trillion (1015) read/write cycle endurance with 10 years of data retention at 85° C or 151 years at 65° C.

The family is available in RoHS-compliant industry-standard packages that are pin compatible with EEPROMs and other nonvolatile memories.
