LPC1114 LPCXpresso board

wellsk's picture

The LPC1114 LPCXpresso board with NXP's ARM Cortex-M0 microcontroller has been designed to make it as easy as possible to get started with Cortex-M0. The LPCXpresso comprises a target board combined with a JTAG debugger. A free Eclipse-based IDE from Code Red is also included.

The LPC1114 has 8 kB SRAM, 32 kB Flash, SSP, I2C, UART, ADC, etc. A Prototype board and a Base board that makes it possible to make experiments and prototyping with many peripherals are also available.


The LPC1114 LPCXpresso board with NXP's ARM Cortex-M0 microcontroller is part of NXP's low-cost development toolchain for LPC families. It has been jointly developed by Embedded Artists, Code Red, and NXP. It is an end-to-end solution for creating applications all the way from evaluation through to production. Here are some of the highlights:

• The target board comes with an integrated JTAG Debugger. No need for a separate emulator!

• A free Eclipse-based IDE and compiler is included (128K download limit)

• Easy upgrade options to full-blown suites (from Code Red) and hardware kits (from Embedded Artists).
