Enrollment Closed

Start Date: 9/18/12 07:00 PM

End Date: 10/8/12 07:00 PM

Kits Offered: 10

Applicants: 52


The LPC4330-Xplorer is a compact and versatile evaluation platform for NXP's new line of dual core microcontrollers.  The board features the LPC4330 dual core microcontroller which contains an ARM Cortex-M4 based digital signal controller with an ARM Cortex-M0 coprocessor designed for embedded applications requiring signal processing. The ARM Cortex-M4 core offers single-cycle Multiply-Accumulate and SIMD instructions and a hardware floating-point unit to support signal processing while the M0 coprocessor handles I/O and digital control processing. The LPC4330 includes 264 KB of data memory, two High Speed USB 2.0 Host/OTG/Devices, advanced configurable peripherals such as the State Configurable Timer (SCT), Serial General Purpose I/O (SGPIO), and SPI Flash Interface (SPIFI) as well as Ethernet, an external memory controller and multiple digital and analog peripherals.
Salient features of the board include:
  • Controller: LPC4330, 100 pin BGA
  • PCB: 4-layer (86mm x 40mm, RoHS Compliant)
  • Two LEDs
  • One user switch and one reset switch
  • Boot select switch
  • 32Mb Quad flash
  • On board crystals for controller, RTC and audio codec
  • On board Ethernet PHY, 50 MHz Oscillator and RJ45 connector with magnetics
  • On board audio codec and audio jacks
  • On board USB host power switch
  • On board Micro SD card slot
  • Two USB ports, one HS (High speed) port and one FS (Full Speed) port
  • 10-pin cortex debug header
  • Unused I/Os brought to a header

What we would like to see in the road test?
The NGX LPC4330 Xplorer board features the LPC4330 dual-core Cortex-M4/Cortex-M0 digital signal controller. What we would like to see in this road test are projects that take advantage the dual-cores and one or more advanced peripherals available on the Xplorer board (HS/FS USB, Ethernet, SDIO, SPIFI, SGPIO, SCT). Examples could include:
  • Applications that use the Cortex-M4 core for signal processing (free DSP algorithms available from ARM as part of CMSIS release at
  • Audio processing on the Cortex-M4 and USB connectivity on the Cortex-M0 (using onchip device drivers or free nxpUSBlib software)
  • Machine vision using either the SCT or SGPIO as a camera interface (code available from NXP)
