Author: speedsthatbeat

Creation date:

Evaluation Type: Evaluation Boards

Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?:

What were the biggest problems encountered?: some issues with the reset (silicon issue) some of the code examples do not work as expected.

Detailed Review:

LPC4330 xplorer evaluation board  from NGX technologies allows experimentation with  LPC4330 a one of the first microcontrollers with asymmetric dual core a cortex M4 and a cortex M0.  The key specs of the boars are:


  • 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


Kit Contents 

  • LPC4330-Xplorer Evaluation Board 
  • 1 meter USB AM to Micro B 
  • 0.2 meter USB AF to Micro B


In addition the kit received included also a a Keil ULINK/ME programmer.with its own cables.


First observations


a) The board comes with pre-loaded peripheral verification program that can be used to test the board functionality.


b) There is a silicon issue on the current version of the chip so that you need to push the reset switch  twice to make it work.


c) In the quick start guide  guide fig. 6 is not correct. The connector to the ULINK/ME  is in opposite direction in the board I am reviewing

To be continued stay tuned.,
