Overview
Description
The RH850/U2A 292-pin Piggyback Board supports all devices of the RH850/U2A series in a 292-pin package. It can be used standalone or in combination with the mainboard of the RH850 evaluation platform. The modular RH850 evaluation platform, consisting of mainboards and piggyback boards, is a platform for evaluating the features and performance of Renesas 32-bit RH850 microcontrollers.
Features
- Can be used with all mainboards of the RH850 Evaluation Platform
- Socket for mounting the MCU
- 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 the onboard voltage regulator or via 4mm banana jack (red)
- 14-pin Renesas Debug Connector to connect a Renesas or 3rd-party emulator
- Offering LPD (4-pin) and JTAG debug connection support
- Offering serial flash programming support for the RH850 on-chip flash memory
- On-board interface connector:
- Renesas High-Speed Serial I/F (RHSIF)
- Multichannel Serial Peripheral Interface (MSPI)
- Automotive Ethernet Port 100/1000BASE-T1
- Each pin of the device is accessible via a 2.54mm pitch connector (double row)
- External clock circuit with an exchangeable 16MHz, 20MHz, 24MHz, or 40MHz crystal resonator
- 8x signal LEDs, 3x power supply LEDs (5.0V, 3.3V 1.12V)
- Reset circuit/switch
- Jumpers for device mode selection

... toggle an LED by configuring the PORT.AP2 as output and xor the port. What am I missing / doing wrong with the timer? My environment is: Board: Y-RH850-U2A-292PIN-PB-T1-V2Smart Configurator configuration: - Default clock configuration - TAUJ0 configuration: - Debugging generated code with breakpoints: Regards, Josymar
Feb 7, 2025 - RH850 U2A: E2 emulator cannot connect after package change (292-pin → 176-pin) – what should I check?
Hello, I’m having an issue connecting an RH850 U2A target with the Renesas E2 emulator (e2 studio / GDB Server). This used to work on our previous setup, but after moving from a 292-pin(RH850 U2A6 Ev board) package to a 176-pin package(custom board), the debugger ...
