    Hello Tanvi,

    From the data sheets for both devices, the RAM,FLASH and ID ROM for the bq2019 and bq26200 appear to be identical.

    Page 10 of the bq26200 datasheet provides the memory map for the device.  The memory map for the bq2019 can be found on page 11. You can look at them and verify the locations and size.

    Thanks,

    Hello,

    I'm not quite sure just exactly what you are trying to do or what you are asking.

    Are you asking how to use the commands to read data from the flash register then in your code do some calculations on them?  Or are you trying to figure out what the values mean when you read them?

    Since I'm not clear on your question, I suggest you look at page  13 for the bq2019.  You can see how the data is transfered LSB first.  The commands are listed on the next page. A read of the location would have a 0 in the MSB.

    Hope that helps.
