Excelon™ Ferroelectric-RAM (F-RAM): The Lowest-Power Nonvolatile Memory

Wednesday, September 4, 2019 - 14:00

Cypress introduces EXCELONTM LP, the Industry’s Lowest Power, Most Reliable, MissionCritical Non-volatile memory for Portable Medical, Wearable and IoT Applications

ExcelonTM LP, Cypress’ next-generation Ferroelectric RAM (F-RAM), delivers the industry’s most reliable missioncritical non-volatile memory by combining ultra-low-power operation with unlimited read/write cycle endurance. Excelon LP supports multiple power saving modes including hibernate, deep power-down and standby, combined with 20MHz to 50MHz SPI. Offered in 4Mb and 8Mb densities in EIAJ and ultra-small footprint GQFN packages, Excelon LP is the ideal data-logging memory for small form factor, power-sensitive applications. 


Up-to 150x reduction in typical standby current (1 μA) and hibernate current (0.1 μA) compared to current F-RAMs

Greater than 10x increase in performance with the addition of a 108 MHz QSPI, compared to competing SPI F-RAMs

Offers NoDelay™ writes to capture data instantly with no soak time requirement and without any additional components for power back-up

2-Mbit, 4-Mbit, and 8-Mbit density options

Operating voltage range: 1.71–1.89V and 1.80–3.60V

Commercial (0°C to +70°C), Industrial (-40°C to +85°C), Auto-A (-40°C to +85°C) and Auto-E (-40°C to +125°C) temperature grades

Excelon LP for Portable Medical, Wearable, and IoT Devices

  • Provides multiple power-saving modes, including hibernate, deep power-down and standby
  • Consumes 200x less energy than EEPROM and 3,000x less energy than NOR Flash products
  • Offers read/write endurance of 1,000 trillion write cycles to log data every millisecond for more than 3,000 years
  • Introduces 8 Mbit density F-RAM, the highest-density Serial F-RAM, to meet the growing data-logging requirement in these applications
  • Available in small footprint ~10mm2, 8-pin GQFN package

Excelon Ultra for High-Performance Industrial Applications

  • Provides a low-pin-count 108 MHz QSPI interface that is as fast as a parallel interface with 35 ns burst access time
  • Offers read/write endurance of 100 trillion cycles to log data continuously for 15-20 years at 85°C
  • Replaces a multi-component solution (SRAM + battery + power management controller) with a single-chip solution and thereby improves reliability and reduces the BOM cost

Excelon Auto for Automotive Applications

  • AEC-Q100-qualified and Functional Safety (ISO 26262)-compliant memory
  • Offers read/write endurance of 10 trillion cycles to log data every 10 microseconds for 20 years
  • Replaces a multi-component solution (SRAM + battery + power management controller) with a single-chip solution improve reliability and reduce the BOM cost
