LPC84x
32-bit Arm Cortex-M0+ microcontroller
11.3 Power consumption
Power measurements in active, sleep, deep-sleep, and power-down 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.
[1] Typical ratings are not guaranteed. The values listed are for room temperature (25 C), VDD = 3.3 V.
[2] Characterized through bench measurements using typical samples.
