LPC1315/16/17/45/46/47
32-bit ARM Cortex-M3 microcontroller
9.2 Power consumption
Power measurements in Active, Sleep, and Deep-sleep modes were performed under the
following conditions (see LPC1315/16/17/45/46/47 user manual):
• Configure all pins as GPIO with pull-up resistor disabled in the IOCON block.
• Configure GPIO pins as outputs using the GPIOnDIR registers.
• Write 0 to all GPIOnDATA registers to drive the outputs LOW.
Conditions: T

from flash;
internal pull-up resistors disabled; BOD disabled; all peripherals disabled in the
SYSAHBCLKCTRL register; all peripheral clocks disabled; USB_DP and USB_DM pulled LOW
externally.
1 MHz - 6 MHz: system oscillator enabled; PLL, IRC disabled.
12 MHz: IRC enabled; system oscillator, PLL disabled.
24 MHz - 72 MHz: IRC disabled; system oscillator, PLL enabled.
