The maximum I
CC,
value can be derated
•
linearly with voltage
•
by 0.85 mA/MHz for lower operating frequency when f
HCLK
= 2 * f
VCLK
•
for lower junction temperature by the equation below where T
JK
is the junction temperature in Kelvin and the result is in milliamperes.

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.
