NXP LPC1768 LPCXpresso Board

LPC1768 LPCXpresso Board

The LPC1768 LPCXpresso board with NXP's ARM Cortex-M3 microcontroller has been designed to make it as easy as possible to get started with Cortex-M3. The LPCXpresso comprises a target board combined with a JTAG debugger. A free Eclipse-based IDE from Code Red is also included. The LPC1768 has 64 kB SRAM, 512 kB Flash, 4xUART, 3xI2C, SPI, 2xSSP, 2xCAN, PWM, USB 2.0 Device/Host/OTG, RTC, Ethernet, I2S, etc.

The LPC1768 LPCXpresso board with NXP's ARM Cortex-M3 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 is included.
  • Easy upgrade options to full-blown suites (from Code Red) and hardware kits (from Embedded Artists).
