Calculation (typical numbers used)
ICC total = Ipwrdown x %pwrdown + %normal x (ICC (ac) + ICC (dc))
= Ipwrdown x %pwrdown + % normal x (%flash x 2.5 mA/MHz x Freq ALE
+ %SRAM x 1.5 mA/MHz x Freq ALE
+ % PLD x 2 mA/MHz x Freq PLD
+ #PT x 400 A/PT
= 50 A x 0.90 + 0.1 x (0.8 x 2.5 mA/MHz x 4 MHz
+ 0.15 x 1.5 mA/MHz x 4 MHz
+2 mA/MHz x 8 MHz
+ 45 x 0.4 mA/PT)
= 45 A + 0.1 x (8 + 0.9 + 16 + 18 mA)
= 45 A + 0.1 x 42.9
= 45 A + 4.29 mA
= 4.34 mA
This is the operating power with no Flash writes or erases. Calculation is based
on IOUT = 0 mA.
