LPC4370

32-bit ARM Cortex-M4/M0 microcontroller

P1_6

[3]

I; PU 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

[3]

I; PU 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 1 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.

R — Function reserved.

SD_VOLT0 — SD/MMC bus voltage select output 0.

P1_9

[3]

I; PU I/O

GPIO1[2] — General purpose digital input/output pin.

U1_RTS — Request to Send output for UART1.

CTOUT_11 — SCT output 11. Match output 3 of timer 2.

I/O

EMC_D2 — External memory data line 2.

R — Function reserved.

I/O

SD_DAT0 — SD/MMC data bus line 0.
