Part Number: TMS320F29H850TM

Hi Experts,

My customer is looking document on the data Flash. There is desciprtion for the program flash in the datasheet and flash API, but there is no data Flash specific descruptions and examples, and cusotmer does not know if it's same to the program flash.

Specifically, they are concerned with the below item:

  • Write/Erase life time
  • Flash opertaion requirements
    • Alignment
    • Minimum Erase Unit
    • API Example

Could you please help finding the documents or confirming if in some aspects it's the same to program flash?

    Hi Hang,

    Write/Erase time is mentioned in the C29 Flash Parameters table of the data sheet.

    Minimum Erase Unit  is sector. This is 2KB for data flash as well. Data Flash sector size mentioned here in this section of Data sheet - 7.5.2 Flash Memory Map

    Alignment requirements and API for programming data flash is also consistent with the ones for program flash. This is showcased in the Example_ProgramDataFlashUsingC29AutoECC() example of examples/driverlib/multi_core/flash/flash_mode3_128_program_cpu1_cpu3.

    Thanks & Regards,
