The 3DFS256M04VS2801 is a 256 Mbit QSPI NOR Flash embedding an ASIC, a power management block and triplicated NOR Flash memories.
This latch-up immune memory is radiation hardened by design with a protection against potential SEE ensured by TMR mitigation electronics, and an enhanced TID performance controlled by an embedded power on/off switch.
In addition, an ECC flag is present to help the user with error (SEE) management. These features provide the user to improve the functional performance and to extend the lifetime of the module in radiation environments.
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.
