F28M36P63C2: F28M36P63C2 M3/C28-SysClock

Part Number: F28M36P63C2

Hello TI-Team,

currently we drive the 'F28M36P63C2' on both cores the SysClock with 125MHz.

My question would be:

"Is there a way or possibility to drive the M3 core still with 125Mhz and the C28 core with 150Mhz."

Thanks in advance.

Kind regards
WJ

WJ,

This is not possible. The System Clock is set up in such a way that the M3 is always an integer divide of the C28x SYSCLK. if the C28x is operating at 150MHz, the max speed of the M3 will be 75MHz. If the C28x is operating at 125 MHz, the M3 may also operate at 125 MHz (the max speed)

See the following sections/tables in the Datasheet:
- www.ti.com/.../device-comparison
- www.ti.com/.../specifications
- www.ti.com/.../detailed-description - Figure 6-11 System Clock/PLL (there is an error stating that the max speed of the M3 core is 100 MHz, it should say 125 MHz.)

Thanks.
-Mark

Hi Mark,

Your answer is what I did assume.

Thanks
