When designing development boards what style JTAG connector should I use?

Applies to: Multi-ICE, RealView ICE and Trace (RVI / RVT)


For new designs we recommend customers to use the new 20-pins JTAG connector. The pin-out of this connector is described in Appendix F of the Multi-ICE v2.2 User Guide.

If your board has a 14-pin JTAG connector, you can use a 20-pin to 14-pin adaptor board to connect Multi-ICE or RealView ICE. For more information see the FAQ entry: My board has a 14-pin JTAG connector. Can I use Multi-ICE or RealView ICE with it?
