Introduction
Philips LPC2138 Target Board is an evaluation and a development system for Philips ARM7TDMI-S based
LPC2138 microcontroller. The ITLPC2138 package consists of a USB cable and a target board populated with
Philips LPC2138 CPU, minimum peripherals, JTAG debug connector, ETM trace connector and an on-board
integrated iSYSTEM debugger.
The user can write and debug the application using the on-board integrated iSYSTEM debugger, which connects
to the PC through the USB connection. The board requires no external power supply since it’s powered from the
PC USB port.
An external ARM7TDMI-S debugger (including e.g. ETM support) can be used for debugging as an alternative
to the on-board integrated debugger.
