BQ40Z50-R2: NVM registers

Aakansha Tuteja

Part Number: BQ40Z50-R2

I am using bq40z50r2 gauge and wanted to know if it has any Non-Volatile memory that I can access for some custom gauge testing. If yes, what would be address of those registers.

I am going to need 10 * 16bit registers for the test.

Thanks!

Hi, Aakansha

The manufacturer info block in data flash can be used for your purpose

Hi Steven

Thanks for the response and pointing me to the manufacturer info block in data flash can be used. Do you happen to know, how many times can data be written/ erase? Does the block itself restricts the data for be written/ erased for limited cycles, since it is meant to be for the MFR data.

Thanks
