Is the dynamic power consumption difference significant for a uC, if it has to raise its activity on the chosen bus protocol from, lets say 50% to 100%?
I look in overall to the uC+CommController+Transceiver consumption.
Is this a mostly a general rule, or there are exceptions?
For an exemplary calculation, I would say the following setup:
- Infineon Tricore TX family MCU (tx29)
- TJA 1081B Flexray Transceiver OR TJA 1145 CAN FD transceiver
- 100-120 ohm impedance ensured in physical layer
