LPC1315/16/17/45/46/47
32-bit ARM Cortex-M3 microcontroller
[3] System oscillator enabled; PLL and IRC disabled.
[4] IRC enabled; system oscillator disabled; system PLL disabled.
[5] I
DD
measurements were performed with all pins configured as GPIO outputs driven LOW and pull-up resistors disabled.
[6] BOD disabled.
[7] All peripherals disabled in the AHBCLKCTRL register. Peripheral clocks to USART, SSP0/1 disabled in the syscon block.
[8] USB_DP and USB_DM pulled LOW externally.
[9] Low-current mode PWR_LOW_CURRENT selected when running the set_power routine in the power profiles.
[10] IRC disabled; system oscillator enabled; system PLL enabled.
[11] WAKEUP pin pulled HIGH externally. An external pull-up resistor is required on the RESET
pin for the Deep power-down mode.
[12] Including voltage on outputs in 3-state mode.
[13] V
DD
supply voltage must be present.
[14] 3-state outputs go into 3-state mode in Deep power-down mode.
[15] Allowed as long as the current limit does not exceed the maximum current allowed by the device.

[17] Includes external resistors of 33 1 % on USB_DP and USB_DM.
9.1 BOD static characteristics
[1] Interrupt levels are selected by writing the level value to the BOD control register BODCTRL, see
