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

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.

Highlights

  • 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

  • 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

Portable and Implantable Medical Devices

The latest-generation of portable and implantable medical devices continuously record large amounts of patient data and provide over-the-air diagnostics. Extended battery life, high reliability and ensuring the smallest form-factor are key design problems that implantable medical device designers face. Click here to learn how Excelon™ F-RAMs solve these problems.

 

Fitness Tracker

The latest-generation fitness trackers continuously record large amounts of user data to provide valuable insights about the user’s health, fitness and general well-being. Fitness trackers also continue to shrink in size and have taken ultra-small form factors, like rings. Maximizing battery life and ensuring the smallest form-factor are key design problems that fitness tracker designers face. Click here to learn how Excelon F-RAMs solve these problems.

 

Programmable Logic Controller (PLC)

PLCs are required to continuously log real-time system data, and capture the system state data, automatically on power loss or system failure. This is required to enable efficient and safe factory operation as well as advancements like predictive analytics and preventive maintenance. Click here to learn why Excelon F-RAMs are the ideal memory for the highly demanding data-logging needs of PLCs.

 

ADAS Vision System

Camera-based vision systems form an integral part of ADAS and are the key to driver assistance functions, such as collision avoidance, and can also support the driver in reducing the severity of an accident. As motor vehicles become autonomous, there is an urgent need for the highest reliability event-data-recorders in ADAS vision systems, to ensure last event capture. Click here to learn how Excelon F-RAMs enable instant and reliable data-capture in ADAS vision systems.
