Letter of Volatility for R Series Devices Hardware: Reconfigurable I/O (RIO)>>R Series
Problem: I need official confirmation that sensitive data passing through National Instruments R Series devices will be erased when the device loses power. Solution: Here is a list of the user accessible memory available on our current selection of R Series products. The list below also contains the type and size of memory in each device. When the device is powered off volatile memory loses its contents while nonvolatile memory retains its contents. R Series devices use nonvolatile memory to store the bitfile of the LabVIEW FPGA VI so it can be loaded to the FPGA every time the device powers up. To remove the bitfile of any VI stored in the nonvolatile flash, you can simply replace it by downloading a new bitfile to the flash. Since there can only be one bitfile in flash memory at a time, downloading a new VI will erase the previous bitfile. With NI-RIO 2.1 and later you can erase the bitfile stored on the flash memory from LabVIEW. For more details, refer to KnowledgeBase 3VSE6QL7: Erasing FPGA Memory. PCI/PXI 7811R
