(1)

The maximum ICC, value can be derated

•

linearly with voltage

•

by 0.76 mA/MHz for lower operating frequency when fHCLK= fVCLK

•

for lower junction temperature by the equation below where TJK is the junction temperature in Kelvin and the result is in milliamperes.

60 - 0.001 e0.026 T

(2)

The maximum ICC, value can be derated

•

linearly with voltage

•

for lower junction temperature by the equation below where TJK is the junction temperature in Kelvin and the result is in milliamperes.

60 - 0.001 e0.026 T

(3)

LBIST and PBIST currents are for a short duration, typically less than 10 ms. They are usually ignored for thermal calculations for the

device and the voltage regulator

(4)
