BQ34110: Full access key on BQ34110 EVM

Mickael Chouteau36

Part Number: BQ34110

Hi,

I'm would like to use the BQ34110 EVM but on the EVM Guide, I can read :

The bq34110 comes up UNSEALED but not in FULL ACCESS. The keys to enter FULL
ACCESS must be sent to the device before being able to access the data memory.

I would like to know what is the key I should use to get full access on a new EVM ?

And what is the process to send this key from BQ Studio ?

Thanks a lot for your support,

Mickael

Hi Mickael,
Please refer to the section 4.3 Sealing/Unsealing Data Flash Access from the TRM available at www.ti.com/.../sluubf7.pdf

Hi David,

Thanks a lot for your quick reply.
I have read the section 4.3 of the TRM and from what I understand, the full access key is 0x12345678.
So in BQ Studio, when I click on the Unlock Full Access button, a windows opens and the 8 digit hexadecimal key i have to enter in is 12345678 ?

Thanks for your support,
Mickael
