Hi TI Team，

1、What are the differences between BQ78350DBTR-R1 and BQ78350-R1A? Are their firmware compatible?

2. Currently, the customer has projects using the BQ78350DBTR-R1 and it has been in mass production for many years. In the past, TI's original factory promoted that the BQ78350DBTR-R1 has become EOL and no new product designs will be launched for its use. It can be replaced by the new generation BQ78350-R1A. Therefore, the customer is currently evaluating the differences between the two. And after replacement, ensure that the mass-produced products are not affected by quality.

Hello,

For firmware differences, please refer to this E2E.

Also, when you download our firmware from ti.com, it should come with release notes stating differences.

Hello,

If the battery pack uses new firmware, do the upper-level communication and addresses all need to be reconfigured? Thanks.
