LPC4350/30/20/10

32-bit ARM Cortex-M4/M0 microcontroller

P1_5

[2]

I/O

GPIO1[8] — General purpose digital input/output pin.

CTOUT_10 — SCT output 10. Match output 3 of timer 3.

R — Function reserved.

EMC_CS0 — LOW active Chip Select 0 signal.

USB0_PWR_FAULT — Port power fault signal indicating

overcurrent condition; this signal monitors over-current on

the USB bus (external circuitry required to detect

over-current condition).

I/O

SSP1_SSEL — Slave Select for SSP1.

I/O

SGPIO15 — General purpose digital input/output pin.

SD_POW — SD/MMC power monitor output.

P1_6

[2]

I/O

GPIO1[9] — General purpose digital input/output pin.

CTIN_5 — SCT input 5. Capture input 2 of timer 2.

R — Function reserved.

EMC_WE — LOW active Write Enable signal.

R — Function reserved.

I/O

SGPIO14 — General purpose digital input/output pin.

I/O

SD_CMD — SD/MMC command signal.

P1_7

[2]

I/O

GPIO1[0] — General purpose digital input/output pin.

U1_DSR — Data Set Ready input for UART1.

CTOUT_13 — SCT output 13. Match output 3 of timer 3.

I/O

EMC_D0 — External memory data line 0.

USB0_PPWR — VBUS drive signal (towards external

charge pump or power management unit); indicates that

VBUS must be driven (active HIGH).

Add a pull-down resistor to disable the power switch at

reset. This signal has opposite polarity compared to the

USB_PPWR used on other NXP LPC parts.

R — Function reserved.
