LPC2387

Single-chip 16-bit/32-bit microcontroller

P3[26]/MAT0[1]/

PWM1[3]

26[1]

I/O

P3[26] — General purpose digital input/output pin.

MAT0[1] — Match output for Timer 0, channel 1.

PWM1[3] — Pulse Width Modulator 1, output 3.

P4[0] to P4[31]

I/O

Port 4: Port 4 is a 32-bit I/O port with individual direction controls for each bit.

The operation of port 4 pins depends upon the pin function selected via the pin

connect block. Pins 0 through 27, 30, and 31 of this port are not available.

P4[28]/MAT2[0]/

TXD3

82[1]

I/O

P4[28] — General purpose digital input/output pin.

MAT2[0] — Match output for Timer 2, channel 0.

TXD3 — Transmitter output for UART3.

P4[29]/MAT2[1]/

RXD3

85[1]

I/O

P4[29] — General purpose digital input/output pin.

MAT2[1] — Match output for Timer 2, channel 1.

RXD3 — Receiver input for UART3.

TDO

1[1]

TDO — Test Data Out for JTAG interface.

TDI

2[1]

TDI — Test Data In for JTAG interface.

TMS

3[1]

TMS — Test Mode Select for JTAG interface.

TRST

4[1]

TRST — Test Reset for JTAG interface.

TCK

5[1]

TCK — Test Clock for JTAG interface. This clock must be slower than 1

⁄6 of the

CPU clock (CCLK) for the JTAG interface to operate.

RTCK

100[1]

I/O

RTCK — JTAG interface control signal.

Note: LOW on this pin while RESET is LOW enables ETM pins (P2[9:0]) to

operate as trace port after reset.

RSTOUT

RSTOUT — This is a 3.3 V pin. LOW on this pin indicates LPC2387 being in

Reset state.

Note: This pin is available in LPC2387FBD100 devices only (LQFP100

package).

RESET

17[7]

External reset input: A LOW on this pin resets the device, causing I/O ports and

peripherals to take on their default states, and processor execution to begin at

address 0. TTL with hysteresis, 5 V tolerant.

XTAL1

22[8]

Input to the oscillator circuit and internal clock generator circuits.

XTAL2

23[8]

Output from the oscillator ampliﬁer.

RTCX1

16[8]

Input to the RTC oscillator circuit.

RTCX2

18[8]

Output from the RTC oscillator circuit.

VSS

15, 31,

41, 55,

72, 97,

83[9]

ground: 0 V reference.

VSSA

11[10]

analog ground: 0 V reference. This should nominally be the same voltage as

VSS, but should be isolated to minimize noise and error.

VDD(3V3)

28, 54,

71, 96[11]

3.3 V supply voltage: This is the power supply voltage for the I/O ports.

VDD(DCDC)(3V3)

13, 42,

84[12]

3.3 V DC-to-DC converter supply voltage: This is the supply voltage for the

on-chip DC-to-DC converter only.
