USB-622x/625x/628x Volatility Letter: Memory Types, Procedures, And Part Numbers.pdf

Key Points:

Volatile Memory: Requires power to retain data. Data is lost when power is removed. Examples include captured waveforms in applications.
Non-Volatile Memory: Retains data even without power. Contains essential boot, configuration, calibration, and power-up states.
User Accessible: Read/write addressable using publicly available NI tools (e.g., Driver API, System Configuration API, MAX).
System Accessible: Read/write addressable but not requiring physical alteration of the product.
Sanitization (Clearing): Removes data from User Accessible storage locations using standard read/write commands, adhering to NIST Special Publication 800-88 Revision 1 guidelines.

Board Assembly Part Number Identification:

Follow the instructions in Section 1 to determine your product's specific Board Assembly Part Number and Revision. The format is "P/N: ######a-vvL", where 'a' indicates a revision letter and 'vv' is a type identifier (and 'L' for RoHS compliance).

Sanitization Procedures:

Volatile Memory (Application Specific Data): Data loss occurs upon power removal. No specific sanitization steps are needed as it's inherently volatile.
Non-Volatile Memory (Calibration Metadata & Other Essential Data):

Device Configuration Flash: Use the NI DAQmx API to clear user-accessible areas of the Device Configuration EEPROM. Refer to www.ni.com/info and enter info code DAQmxLOV for instructions.
Other Non-Volatile Storage: Follow specific procedures outlined in the document for each type (e.g., media storage, FPGA bitstream, calibration data).
