7.1 Architectural overview
The LPC2364/66/68 microcontroller consists of an ARM7TDMI-S CPU with emulation
support, the ARM7 Local Bus for closely coupled, high speed access to the majority of
on-chip memory, the AMBA Advanced High-performance Bus (AHB) interfacing to high
speed on-chip peripherals, and the AMBA Advanced Peripheral Bus (APB) for connection
to other on-chip peripheral functions. The microcontroller permanently configures the
ARM7TDMI-S processor for little-endian byte order.

Description
TDI — Test Data in for JTAG interface.
TMS — Test Mode Select for JTAG interface.
TRST — Test Reset for JTAG interface.
TCK — Test Clock for JTAG interface.
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 — LOW on this pin indicates LPC2364/66/68 being in Reset state.
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.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Input to the RTC oscillator circuit.
Output from the RTC oscillator circuit.
Ground: 0 V reference
Analog Ground: 0 V reference. This should nominally be the same voltage as V
should be isolated to minimize noise and error.
3.3 V Power Supply: This is the power supply voltage for the I/O ports.
3.3 V DC-to-DC Power Supply: This is the power supply for the on-chip DC-to-DC
converter only. If the DC-to-DC is not used, these pins must be unconnected.
Analog 3.3 V Power Supply: This should be nominally the same voltage as V
should be isolated to minimize noise and error. This voltage is used to power the ADC
and DAC.
ADC Reference: This should be nominally the same voltage as V
isolated to minimize noise and error. Level on this pin is used as a reference for ADC
and DAC.
RTC Power Supply: 3.3 V on this pin supplies the power to the RTC.
