Features & Applications

Excelon™, Cypress’ next-generation Ferroelectric RAM (F-RAM), delivers the industry’s lowest-power mission-critical nonvolatile memory, by combining ultra-low-power operation with high-speed interfaces, instant nonvolatility and unlimited read/write cycle endurance. This makes Excelon the ideal data-logging memory for portable medical, wearable, IoT sensor, industrial and automotive 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.
