To help jump start the evaluation and development based on the LPC54100, NXP has released the Xpresso board. In addition to the LPC54100 MCU, this board contains MCU power consumption measurement circuit, JTAG debugger over high speed USB and several I/O connectors for easy prototyping. The board can be directly powered from the USB port or can also be powered from an external power supply. The board is supported by NXP LPCXpresso IDE as well as Keil and IAR development tools.
