XK-1A Development Kit Design Support

XK-1A Development Kit

Part #: XK-1A
Silicon on Board: XS1-L8A-64-TQ128

The XK-1A is a low cost development board for exploring multicore micro controller designs based on the XS1-L8-64 multicore microcontroller. Multiple XK-1A boards can be linked together in a chain and two I/O expansion areas are provided for connecting additional components to the XK-1A. Design files for example add-on boards are available, including an SD card reader, a Bluetooth adapter and a Control Card.

The XK-1A is available as a kit with an xTAG-2 debug adapter that can be connected to the XK-1A to provide a JTAG interface to the board from a PC, or as an individual board if you want to chain multiple XK-1As together (one xTAG-2 can be used for several boards).


  • Single XS1-L8-64 device
  • 400 MIPS
  • 8 cores
  • 64KB RAM
  • 8KB OTP memory
  • Four user-configurable LEDs and two push-button switches
  • Two 20-way XSYS connectors for xTAG-2 debug adapter and additional XK-1As
  • Two 16-way IDC headers for connecting additional components
  • 24 I/O user expansion

The XK-1A can be powered directly from the xTAG-2 connector or from an external 5V power supply.
