Excelon™ Ferroelectric-RAM (F-RAM)

Infineon's F-RAM is ideal for portable medical, wearable, IoT sensor, industrial, and automotive applications

Image of Infineon's Excelon™ Ferroelectric-RAM Memory Infineon's Excelon is next-generation Ferroelectric RAM (F-RAM) which 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.

Features

  • 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 Quad SPI (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 Mb, 4 Mb, and 8 Mb density options
  • Operating voltage range: 1.71 V to 1.89 V and 1.80 V to 3.60 V
  • 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 Individual Features
  • Read/write endurance of 1,000 trillion write cycles to log data every millisecond for more than 3,000 years
  • Consumes 200x less energy than EEPROM and 3,000x less energy than NOR Flash products
  • Provides multiple power-saving modes, including hibernate, deep power-down and standby
  • Available in small footprint ~10 mm², 8-pin GQFN package
Excelon-Auto Individual Features
  • Read/write endurance of 10 trillion cycles to log data every 10 microseconds for 20 years
  • AEC-Q100-qualified and functional safety (ISO 26262)-compliant memory
  • Captures data instantly with no soak time requirement and no additional back-up components

Excelon-Ultra Individual Features

  • Read/write endurance of 100 trillion cycles to log data continuously for 15 to 20 years at +85°C
  • Low-pin-count 108 MHz QSPI interface that is as fast as a parallel interface with 35 ns burst access time

Example applications

  • Excelon-LP for portable medical, wearable, and IoT device applications: provides extended battery life, high reliability, and small form factor
  • Excelon-Ultra for industrial automation systems: ideal memory for highly demanding data-logging needs of PLC
  • Excelon-Auto for automated driver-assist systems: enables instant and reliable data capture in ADAS vision systems
