LPC408x/7x

32-bit ARM Cortex-M4 microcontroller

P0[10]

T15

L10

[3]

I; PU I/O

P0[10] — General purpose digital input/output pin.

U2_TXD — Transmitter output for UART2.

I/O

I2C2_SDA — I2C2 data input/output (this pin does not

use a specialized I2C pad).

T3_MAT0 — Match output for Timer 3, channel 0.

R — Function reserved.

LCD_VD[5] — LCD data.

P0[11]

100

R14

P12

[3]

I; PU I/O

P0[11] — General purpose digital input/output pin.

U2_RXD — Receiver input for UART2.

I/O

I2C2_SCL — I2C2 clock input/output (this pin does not

use a specialized I2C pad).

T3_MAT1 — Match output for Timer 3, channel 1.

R — Function reserved.

LCD_VD[10] — LCD data.

P0[12]

[5]

I; PU I/O

P0[12] — General purpose digital input/output pin.

USB_PPWR2 — Port Power enable signal for USB port

I/O

SSP1_MISO — Master In Slave Out for SSP1.

ADC0_IN[6] — A/D converter 0, input 6. When

configured as an ADC input, the digital function of the pin

must be disabled.

P0[13]

[5]

I; PU I/O

P0[13] — General purpose digital input/output pin.

USB_UP_LED2 — USB port 2 GoodLink LED indicator.

It is LOW when the device is configured (non-control

endpoints enabled), or when the host is enabled and has

detected a device on the bus. It is HIGH when the device

is not configured, or when host is enabled and has not

detected a device on the bus, or during global suspend. It

transitions between LOW and HIGH (flashes) when the

host is enabled and detects activity on the bus.

I/O

SSP1_MOSI — Master Out Slave In for SSP1.

ADC0_IN[7] — A/D converter 0, input 7. When

configured as an ADC input, the digital function of the pin

must be disabled.
