4Mb serial F-RAMs feature a 40-Mhz Serial Peripheral Interface

Cypress Semiconductor Corp. introduced a family of 4Mb serial Ferroelectric Random Access Memories (F-RAMs), which are the industry’s highest density serial F-RAMs. The 4Mb serial F-RAMs feature a 40-Mhz Serial Peripheral Interface (SPI), a 2.0V to 3.6V operating voltage range and are available in industry-standard, RoHS-compliant package options. All Cypress F-RAMs provide 100-trillion read/write cycle endurance with 10-year data retention at 85˚C and 151 years at 65˚C.

Cypress F-RAMs are ideal solutions for applications requiring continuous and frequent high-speed reading and writing of data with absolute data security. The 4Mb serial F-RAM family addresses mission-critical applications such as industrial controls and automation, industrial metering, multifunction printers, test and measurement equipment and medical wearables.

“Mission-critical systems require high-performance memories that can capture data instantly and reliably on power loss,” said Rainer Hoehler, Vice President of the Nonvolatile Products Business Unit at Cypress. “Cypress’s new 4Mb F-RAM family delivers absolute data security with the industry’s highest-density serial F-RAM devices.”

The 4Mb serial are sampling today in industry-standard 8EIAJ and 8TDFN packages, with production expected in the fourth quarter of 2015. Learn more about the 4Mb F-RAM family at
