LPC1110/11/12/13/14/15

32-bit ARM Cortex-M0 microcontroller

[1]

Pin state at reset for default function: I = Input; O = Output; PU = internal pull-up enabled (pins pulled up to 2.6 V for

LPC111x/101/201/301, pins pulled up to full VDD level on LPC111x/002/102/202/302 (VDD = 3.3 V)); IA = inactive, no pull-up/down

enabled.

[2]

5 V tolerant pad. RESET functionality is not available in Deep power-down mode. Use the WAKEUP pin to reset the chip and wake up

from Deep power-down mode. An external pull-up resistor is required on this pin for the Deep power-down mode. See Figure 52 for the

reset pad configuration.

[3]

5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors and configurable hysteresis (see Figure 51).

[4]

I2C-bus pads compliant with the I2C-bus specification for I2C standard mode and I2C Fast-mode Plus. The pin requires an external

pull-up to provide output functionality. When power is switched off, this pin is floating and does not disturb the I2C lines. Open-drain

configuration applies to all functions on this pin.

[5]

5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors, configurable hysteresis, and analog input.

When configured as a ADC input, digital section of the pad is disabled, and the pin is not 5 V tolerant (see Figure 51).
