Table 37. Example of PSD Typical Power Calculation at V
CC
= 5.0V (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)
= 45 PT
% of total product terms
= 45/182 = 24.7%
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 2.5mA/MHz x Freq ALE
+ %SRAM x 1.5mA/MHz x Freq ALE
+ % PLD x (from graph using Freq PLD))
= 50μA 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)
= 45μA + 0.1 x (8 + 0.9 + 24)
= 45μA + 0.1 x 32.9
= 45μA + 3.29mA
= 3.34mA
This is the operating power with no EEPROM WRITE or Flash memory Erase cycles in progress. Calculation is based
on I
OUT
= 0mA.
