Hi!
How can I determine total current consumption of an MCU-DSP etc?
I have read from datasheets for dsPIC (30MIPS, 16xPLL, 5V, 25degC, PDIP40) that its Idd is 132mA at that conditions and that its maximum consumption current on all ports (from absolute maximum ratings) is 200mA.
Is my total consumption current sum of these two currents or
only one greater than other?
I need that in order to find appropriate heatsink for LM7805 (Vin=15/Vout=5V).
Thanks.
Regards.
