With this hands-on process, you can determine the hardware and software requirements for current and future product development.
The LPC1769 ARM Evaluation Board ships with the LPC1769 device that is a superset of several other device variants of the LPC17xx microcontroller series. The LPC1769 Board contains all the hardware components required in a single-chip LPC17xx system.
The connectors on the LPC1769 arm evaluation board provide easy access to many of the LPC1769's on-chip peripherals.
USB 2.0 Full Speed Interface Standard USB connectors for USB Device, USB-OTG, USB Host and UART via USB on the LPC1769 board for applications requiring USB communications.
Dual Serial Ports Standard DB9 connectors are on the LPC1769 for both of the LPC1700's serial ports. Your application may use either of these ports.
Dual CAN Ports Standard DB9 connectors are on the LPC1769 arm evaluation board for applications requiring CAN communications. Your application may use either or both of these ports, or they may be disabled with a configuration jumper.
LCD Display A detachable, 240x320 TFT, color LCD display. You may use this graphic display device to show real-time debug and program status messages.
MicroSD Card Connector A MicroSD Card connector for developing applications requiring access to MicroSD Cards.
Joystick A 5-position joystick. Your application may use this to control port pin input.
LF Amplifier An LF Amplifier on the LPC1769 connects the D/A output of the LPC1700 device to a speaker. You may use this LF Amplifier to generate sound.
Analog Voltage Control for ADC Input An adjustable analog voltage source is on the LPC1769 board for testing the Analog to Digital output feature of the LPC1700. A configuration jumper enables and disables this feature.
JTAG and Cortex/ETM Download and Debug The LPC1769 board incorporates both a JTAG interface and a Cortex Debug + ETM interface. When coupled with the ULINK2 USB-JTAG adapter, the Serial Wire JTAG interface allows flash programming and debugging. With the ULINKPro adapter, the Cortex Debug/ETM interface allows flash programming and instruction trace debugging.

NXP Cortex-M3 Products
NXP and ARM Expand Strategic Relationship With Major Licensing Agreement includes ARM Cortex-M3 processor for microcontrollers (32-bit), since Feb. 5, 2008.
Starting in 2008, NXP plans to release several new microcontroller series based on the ARM Cortex-M3 processor. The NXP MCUs will target a wide range of applications including consumer, industrial, medical and automotive systems, with a Memory Accelerator Module (MAM) featuring NXP's embedded high-speed Flash memory design, as well as support for Ethernet and other communications peripherals such as USB and CAN.
First NXP microcontrollers based on the Cortex-M3 processor is LPC17xx series.
The LPC17xx are ARM Cortex-M3 based microcontrollers for embedded applications featuring a high level of integration and low power consumption. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration.
