Can TMS320F28069 save variable in its own memory permanently? (when power goes down the variables should be there.)

Hi Harshana,

Are you wanting to save a static or dynamic value? You can save a static value to a location in Flash using the Flash API.

See the below within C2000ware for more info:

Best,

Kevin

Hi Harshana,

An external EEPROM would be better to use then. EEPROMs commonly have byte-to-byte program/erasing where Flash requires you to erase the entire sector. Additionally the write operations are typically much faster.

See the below Application report for more info:
