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, 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).

Tamb =25 C; CPU clock = 208 MHz; I-cache/D-cache, MMU disabled; VDD_CORE = 1.2 V;

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.
