PSD module example, typ. power calculation at VCC = 5.0 V (Turbo mode Off)
Conditions
MCU Clock Frequency
= 12 MHz
Highest Composite PLD input frequency
(Freq PLD)
= 8 MHz
MCU ALE frequency (Freq ALE)
= 2 MHz
% Flash memory Access
= 80%
% SRAM access
= 15%
% I/O access
= 5% (no additional power above base)
Operational modes
% Normal
= 40%
% Power-down mode
= 60%
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)
ICC total
= ICC(MCUactive) x %MCUactive + ICC(PSDactive) x %PSDactive + IPD(pwrdown) x
%pwrdown
