Infineon’s NEW 1 and 2Mb rad hard parallel F-RAMs

Infineon’s radiation hardened 1 and 2 Mb non-volatile Ferroelectric RAM (F-RAM) memories offers the utmost reliability and performance for extreme environments.   The F-RAMs are low-power and support a parallel interface configured as 128K x 8 for the 1Mb density and 128K x 16 for the 2Mb density.  Our rad hard parallel F-RAMs are ideal for data storage for sensors and instruments, data logging for satellite calibration data and microcontroller boot code storage.

Our rad hard F-RAM’s virtually infinite endurance, instant non-volatile write technology, greater than 100-year data retention and immune to Single Event Upsets (SEU) is the highest reliable, non-volatile memory for space applications and is a direct replacement for parallel EEPROMs.
