Parameter
VDDCORE rise rate to ensure power-on-reset
VDDCORE fall rate to ensure power-on-reset
Rising threshold voltage: voltage up to which
device is kept under reset by POR on rising
VDDCORE
Falling threshold voltage: voltage when POR
resets device on falling VDDCORE
On falling VDDCORE, voltage must go down to
this value before supply can rise again to ensure
reset signal is released at
Minimum time with VDDCORE <
Time for reset signal to be propagated to system
