PXIe-5764 FlexRIO Digitizer Volatility And Memory Specifications.pdf

Key Points:

Volatile Memory: Requires power to retain data (e.g., captured waveforms).
4GB DRAM available on models -02 and -03 only.
No battery backup for volatile memory.
Non-Volatile Memory: Retains data even without power (e.g., boot information, calibration constants).
2KB EEPROM.
512Mb Flash memory.
256Mb SDRAM for FPGA bitfiles (specific models only).
Data Storage and Backup:
User-accessible storage: Can be written to by user software using APIs like NI's FlexRIO API or System Configuration API. Examples include calibration constants, FPGA bitfiles, and user-generated data.
System-accessible storage: Read/write accessible from the host without physical modification to the device.
Sanitization (Clearing):

Per NIST guidelines, clearing involves overwriting User Accessible storage locations with arbitrary values using standard read/write commands.
The "Read-Write Calibration Data" LabVIEW example project or a custom VI can be used to clear flash memory containing calibration constants.
Procedures:
Procedure 1: Identifies the Board Assembly Part Number and Revision (based on product label).
Procedure 2: Details steps for clearing Flash memory containing calibration constants using a LabVIEW example project or custom VI.
