Conditions
Highest Composite PLD input frequency
(Freq PLD)
=
8 MHz
MCU ALE frequency (Freq ALE)
=
4 MHz
% Flash Access
=
80%
% SRAM access
=
15%
% I/O access
=
5% (no additional power above base)
Operational Modes
% Normal
=
10%
% Power Down Mode
=
90%
Number of product terms used
(from fitter report)
=
45 PT
% of total product terms
=
45/176 = 25.5%
Turbo Mode
=
Off
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 (from graph using Freq PLD)
)
= 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
+ 24 mA)
= 45 A + 0.1 x (8 + 0.9 + 24)
= 45 A + 0.1 x 32.9
= 45 A + 3.29 mA
= 3.34 mA
This is the operating power with no Flash writes or erases. Calculation is based
on IOUT = 0 mA.
