AM6442: Operating Performance Point (OPP)

Kanae

Part Number: AM6442
Other Parts Discussed in Thread: AM5746,

Hi Support Team,

AM5746 had a maximum frequency limit by component for OPP. (For OPP NOM, MPU 1GHz, etc...)
AM6442 datasheet has Speed Grade definition, but no limit for OPP NOM/OD/HIGH, etc.
Is my understanding correct that there is no such limitation in AM6442?

Hello Kanae,

Thank you for the query.

I am not able to understand the query.

For the AM644x we do not have OPP tied to the core voltage.

The 0.75V and 0.85V core provides an option to optimize the number of power rails vs power without change in performance.

Hi Sreenivasa,

Thank you for your quick reply!

This was just checking to be sure from our customer who was using AM5746.
AM644x does not tie OPP to core voltages, which agreed with me.
