Cypress Semiconductor F-RAM Excelon-LP Series

Cypress Semiconductor?F-RAM Excelon-LP Series?is low-power, 4Mbit nonvolatile?memory employing an advanced ferroelectric process. A ferroelectric random access memory (F-RAM) is nonvolatile and?performs reads and writes similar to a RAM. F-RAM provides reliable?data retention for 151 years. The devices?eliminate complexities,?overhead, and system-level reliability problems caused by serial?flash, EEPROM, and other nonvolatile memories.


  • 4Mbit ferroelectric random access memory (F-RAM) logically?organized as 512K × 8

    • Virtually unlimited endurance of 100 trillion (1014) read/write?cycles

    • 151-year data retention (See Data Retention and Endurance?on page 20)

    • NoDelay? writes

    • Advanced high-reliability ferroelectric process

  • Fast serial peripheral interface (SPI)
