LPC15xx
32-bit ARM Cortex-M3 microcontroller
11.1 Power consumption
Power measurements in Active, Sleep, and Deep-sleep modes were performed under the
following conditions:
• Configure all pins as GPIO with pull-up resistor disabled in the IOCON block.
• Configure GPIO pins as outputs using the GPIO DIR register.
• Write 1 to the GPIO CLR register to drive the outputs LOW.
Conditions: T
amb
= 25 C; active mode entered executing code while(1){} from flash; all
peripherals disabled in the SYSAHBCLKCTRL0/1 registers; all peripheral clocks disabled; internal
pull-up resistors disabled; BOD disabled; low-current mode.
1 MHz - 6 MHz: IRC enabled; PLL disabled.
12 MHz: IRC enabled; PLL disabled.
24 MHz to 72 MHz: IRC enabled; PLL enabled.
