% 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))

= 50 µA 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)

= 45 µA + 0.1 x (8 + 0.9 + 24)

= 45 µA + 0.1 x 32.9

= 45 µA + 3.29mA

= 3.34mA

This is the operating power with no EEPROM WRITE or Flash memory Erase cycles in progress. Calculation is based on

IOUT = 0 mA.
