AM5716: in the security boot document, what's the meaning of the temperature(junction)?

Part Number: AM5716
Other Parts Discussed in Thread: TLV707

Tool/software:

AM5716, customer is trying to switch to security-boot SOC

in the security boot document, what's the meaning of the temperature(junction)? 

does it mean the junction temperature should be kept in this range when burn the key into the SOC?

for the 1.8V voltage used to burn the key, is there any timing requirement?

Regards

    Hi Semon,

    > does it mean the junction temperature should be kept in this range when burn the key into the SOC?

    Yes.  Though if you're in a room temp manufacturing facility, this requirement should be easily met.

    The basic sequence is highlighted here:

    Beyond the ordering stated, there are no additional/strict timing requirements.
