ZHCSAB6E October 2012 – May 2018 BQ27545-G1
PRODUCTION DATA.
The bq27545-G1 provides three security modes (FULL ACCESS, UNSEALED, and SEALED) that control data flash access permissions. Data Flash refers to those data flash locations, Table 16, that are accessible to the user. Manufacture Information refers to the two 32-byte blocks.
SECURITY MODE | DATA FLASH | MANUFACTURER INFORMATION |
---|---|---|
FULL ACCESS | R/W | R/W |
UNSEALED | R/W | R/W |
SEALED | None | R (A); R/W (B) |
Although FULL ACCESS and UNSEALED modes appear identical, only FULL ACCESS mode allows the bq27545-G1 to write access-mode transition keys stored in the Security class.
