16/32-bit ARM microcontrollers
10.1 Minimum core voltage requirements
Figure 4
shows the minimum core supply voltage that should be applied for a given core
frequency on pin VDD_CORE to ensure stable operation of the LPC3220/30/40/50.
10.2 Power supply sequencing
The LPC32x0 has no power sequencing requirements, that is, V

DD(EMC)

and V
DDA(3V3)
can be switched on or off independent of each other. An internal circuit
ensures that the system correctly powers up in the absence of core power. During IO
power-up this circuit takes care that the system is powered in a defined mode. The same
is valid for core power-down.
