Part Number: BQ27520-G4
We are designing with BQ27520 because it can be reprogrammed.
I would like some clarification on this section on page 10-
Cell information is stored in the device in non-volatile flash memory. Many of these data flash locations are
accessible during application development. They cannot generally be accessed directly during end-equipment
operation. Access to these locations is achieved by either use of the companion evaluation software, through
individual commands, or through a sequence of data-flash-access commands. To access a desired data flash
location, the correct data flash subclass and offset must be known.
If a certain sequence can be used to program all the flash, then how can you say it can't be accessed in end equipment? Why couldn't our drivers have the ability to program it any time? Would we need to have some special programming station in the factory?
