The RH850/U2A 292pin Piggyback Board supports all devices of the RH850/U2A series in 292pin-package. It can be used standalone or in combination with a mainboard of the RH850 evaluation platform. The modular RH850 evaluation platform consisting of mainboards and piggyback boards is a platform for evaluating features and performance of Renesas 32-bit RH850 microcontrollers.


  • Can be used with all mainboards of the RH850 Evaluation Platform.
  • Socket for mounting the MCU [NOTE: MCU is not included, needs to be ordered separately]
  • 3.3V or 5.0V single supply voltage via 4mm Banana Jacks (2x red, 1x black)
  • Device core voltage VDD either from onboard voltage regulator or via 4mm Banana Jack (red)
  • 14pin Renesas Debug Connector to connect a Renesas or 3rd party emulator
    • offering LPD (4pin) and JTAG debug connection support
    • offering serial Flash programming support for the RH850 on-chip Flash memory.
  • On-board interface connector for
    • Renesas High-Speed Serial I/F (RHSIF)
    • Multichannel Serial Peripheral Interface (MSPI)
  • Automotive Ethernet Port 100/1000BASE-T1
