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, VDD(1V2), VDD(EMC), VDD(IO),
and VDDA(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.
10.3 Power consumption per peripheral
[1]
All three Ethernet clocks are in enabled in the MAC_CLK_CTRL register (see LPC32x0 User manual).

VDD(IO) = 1.8 V; USB AHB, IRAM, and IROM clocks always on; all peripherals are at their default
state at reset. Peripheral clocks are disabled except for peripheral measured.
