This product is an emulation adapter for RH850/U2B. By using in combination with an exchange adapter (sold separately), you can emulate the target microcomputer to be used. 

Debug chip for RH850/U2B is included. The installed debug chip differs depending on the product model name. [ Learn More ]


  • Connecting an emulator which supports Aurora tracing Note 1, such as the IE850A emulator from Renesas, to the emulation adapter enables debugging with the use of a tracing facility.
  • Using the attached 34-pin to 14-pin conversion connector enables connection of the E2 emulator from Renesas.
  • The combination of the emulation adapter connected to the base board included in the package is usable as an evaluation board for the target MCU.


  1. Aurora is a high-speed communications protocol from Xilinx Inc. but is not supported by the E2 emulator.
