(from fitter report)

= Off
Calculation (using typical values)
ICC total
= Ipwrdown x %pwrdown + %normal x (ICC (ac) + ICC (dc))
= Ipwrdown x %pwrdown + % normal x (%flash x 2.5mA/MHz x Freq ALE
+ %SRAM x 1.5mA/MHz x Freq ALE
+ % PLD x (from graph using Freq PLD))
= 50 µA x 0.90 + 0.1 x (0.8 x 2.5mA/MHz x 4 MHz
+ 0.15 x 1.5mA/MHz x 4 MHz
+ 24mA)
= 45 µA + 0.1 x (8 + 0.9 + 24)
= 45 µA + 0.1 x 32.9
= 45 µA + 3.29mA
= 3.34mA
1.
This is the operating power with no EEPROM WRITE or Flash memory Erase cycles in progress. Calculation is based on
IOUT = 0 mA.
