Hi,

We use a P2020 on a board, and only core 0 is used, core 1 is not allowed to boot by configuration.

In case of the core 1 boot even of his boot configuration, we plan to pull-down the CHKSTP_IN1 pin.

Does the consumption will increase with this configuration ?

We don't see any current values with CHKSTP_IN1 maintaned to low level.

Assertion of CKSTP_IN causes all core clocks stopped, this actually disables the core, leaving only static leakages.

The total power consumption should decrease. The exact value may be roughly estimated by comparing power consumptions of P2020 and P2010 (single-core version of the same device). As I can see from two datasheets, this difference is not more than 10%


Have a great day,
