Issue Details

I need official National Instruments documentation of memory capacity and volatility for static DIO and TIO counter/timer devices.

Solution


Here is a list of the current information on some of our static DIO devices. The list below contains the types of memory in each device, the amount, and whether or not the information stored in that memory is retained. Volatile memory loses its contents when the device is powered off while nonvolatile memory retains its contents when the device is powered off.


USB-6525 :
Storage TypeSizeVolatilityAccess Restrictions
Flash Memory16 kBnonvolatile for configurationSoftware protected. No mechanism provided for writing to the EEPROM through the user API. No user data is stored in the EEPROM.
