Electrically Erasable and Programmable ROM (EEPROM) offer on-board and in-orbit programming capabilities as non-volatile memories essential for space applications. 3D PLUS Radiation Tolerant EEPROM stacks guarantee high endurance and exceptional data retention time. Available with 3.3 V or 5.0 V power supply, these memories support various data bus widths including x8b, x32b, and x40b. Encased in compact SOP packages, they are ideal for Surface Mount (SMT) assembly, providing high resistance to harsh thermal and mechanical environments.
Released in 2003, 3D PLUS Radiation Tolerant EEPROM products have been widely utilized as processors’ Boot and Program ROM in high-performance computer boards. They have excelled in a range of space applications, such as scientific deep space missions, Earth observation, launchers, manned space vehicles, and navigation satellites. These EEPROM modules have built a unique flight heritage with successful missions including Exomars 2016, Chang’e 5, H-IIA/H-IIB, Chandrayaan-3, and Orion Artemis.
While EEPROM has proven its reliability, it is no longer recommended for new designs. Instead, we suggest transitioning to Magnetoresistive Random-Access Memory (MRAM). MRAM offers high speed, unlimited read and write endurance, and non-volatile memory capabilities. Both EEPROM and MRAM memories are byte-addressed and operate with active LOW control signals, ensuring protocol compatibility. 3D PLUS MRAM memories also present excellent radiation tolerance, making them an ideal replacement for EEPROM in space applications.
