= 20mA
= 250uA
= I_CC(ac) + I_CC(dc)
= %flash x 2.5mA/MHz x Freq ALE
+ %SRAM x 1.5mA/MHz x Freq ALE
+ % PLD x (from graph using Freq PLD)
= 0.8 x 2.5mA/MHz x 2MHz + 0.15 x 1.5mA/MHz x 2MHz + 24mA
= (4 + 0.45 + 24) mA
= 28.45mA
I_CC total = 20mA x 40% + 28.45mA x 40% + 250uA x 60%
= 8mA + 11.38mA + 150uA
= 19.53mA
This is the operating power with no Flash memory Erase or Program cycles in progress. Calculation
is based on all I/O pins being disconnected and I_OUT = 0mA.
