AC/DC parameters
Table 39. Example of PSD typical power calculation at VCC = 5.0 V (Turbo mode off)
Conditions
(from fitter report)
= 45 PT
% of total product terms = 45/182 = 24.7%
Turbo mode
= 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))
t(s = 50 µA x 0.90 + 0.1 x (0.8 x 2.5mA/MHz x 4 MHz
c + 0.15 x 1.5mA/MHz x 4 MHz
du + 24mA)
ro = 45 µA + 0.1 x (8 + 0.9 + 24)
P = 45 µA + 0.1 x 32.9
te = 45 µA + 3.29mA
ole = 3.34mA
bs 1. This is the operating power with no EEPROM WRITE or Flash memory Erase cycles in progress. Calculation is based on
IOUT = 0 mA.
