Renesas Piggyback Evaluation Board for RH850/F1x (176 pin package)

The Renesas Piggyback Evaluation Board for RH850/F1x (176 pin package) is intended as a user-friendly evaluation tool for the RH850/F1x microcontroller. 


The piggyback board provides a useful evaluation platform for evaluating the Renesas and 3rd party development tools for coding and debugging using E1 emulator and/or Renesas Flash Programmer. 

The piggyback board may be connected to the host PC using the E1 or E2 on chip debugging interface via USB interface. 

The purpose of the board is to enable the user to evaluate the capabilities of the device and its peripherals by giving the user a simple platform on which code can be run only minutes from opening box.

It can also prove an invaluable tool in development by providing a useful test platform for code already debugged using one of our more powerful emulation tools.
