hi there
when i calculate power consumption for a pic system, I would usually find out how much current I am sourcing out of the pins and multiply it with the DC power of 5V (say 3 LEDs with each 25mA which is max sourced out per pin)
my P would be 5 * 75mA
However, if I'm using the UART at a baud rate of 9600 , how do I calculate power consumption now?
Apart from that, how do I exactly calculate the power consumption by a crystal?
According to the 87X datasheet, the Power Dissipation is given by the attached picture. Is power dissipation=power consumption? I would think that the power dissipation is not the consumption but the losses involved.Am I right?
thanks
