Description

The 3DFS256M04VS2801 also provides two distinct QSPI user buses. It allows the module to be updated/reconfigured in flight by another device and thus to enhance its fault tolerance.

Applications

• FPGA (e.g.: V5Q, KU060) configuration
  bitstream
• Boot code storage for microcontrollers and microprocessors

Space Qualification

• Qualified with 3D PLUS ESA certification per ESCC 2566001
• Up to NASA Level 1
• High Longevity and Reliability
• Flight heritage: 3D PLUS expertise in space memories for more than 20 years

From EEPROM, MRAM to NOR Flash
