Table 54. Example of PSD Typical Power Calculation at V
CC
= 3.0 V (with Turbo Mode Off)
Conditions
Highest Composite PLD input frequency
(Freq PLD)
= 8 MHz
MCU ALE frequency (Freq ALE)
= 4 MHz
% Flash memory
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)
= 54 PT
% of total product terms
= 54/217 = 25%
Turbo Mode
= Off
Calculation (using typical values)
I
CC
total
= Ipwrdown x %pwrdown + %normal x (I
CC
(ac) + I
CC
(dc))
= Ipwrdown x %pwrdown + % normal x (%flash x 1.2 mA/MHz x Freq ALE
+ %SRAM x 0.8 mA/MHz x Freq ALE
+ % PLD x (from graph using Freq PLD))
= 50 μA x 0.90 + 0.1 x (0.8 x 1.2 mA/MHz x 4 MHz
+ 0.15 x 0.8 mA/MHz x 4 MHz
+ 15 mA)
= 45 μA + 0.1 x (3.84 + 0.48 + 15)
= 45 μA + 0.1 x 18.84
= 45 μA + 1.94 mA
= 1.98 mA
This is the operating power with no Flash memory Program or Erase cycles in progress. Calculation is based on I
OUT
= 0 mA.
