BQ20Z80: Bq20z80 data flash information is same as Bq20z95?

Part Number: BQ20Z80
Other Parts Discussed in Thread: BQ20Z70


We have a working lab view VI for programming ROM file for the BQ20zXX. This procedure was used by BQ20z75, BQ20z95 and we dont any issue on this fuel gauges.
It should be the same with BQ20z80 but apparently its not working.

The attached document is for BQ20zXX, this is the document we used in writing the code for BQ20z70, BQ20z80 and BQ20z95. Apparently, the BQ20z80 is not working. The issue is after programming our ROM file on BQ20z80, some of the device information like: MFG_FW data version, MFG_HW version, product information are missing and it reads 0. 

Can you check if the data flash number of rows and size are the same with BQ20z95?
