Overview
Description
The RH850/U2A 516-pin Piggyback Board supports all devices of the RH850/U2A series in a 516-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
- 34-pin AURORA Trace Interface Connector
- On-board interface connector:
- Renesas High-Speed Serial I/F (RHSIF)
- Multichannel Serial Peripheral Interface (MSPI)
- 100/1000BASE-TX Ethernet Port with a RJ45 type connector
- Each pin of the device is accessible via a 2.54mm pitch connector (triple 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
