RH850/U2C Starter Kit User's Manual V1.00

Overview

The RH850/U2C Starter Kit is a compact platform for evaluating 32-bit RH850/U2C microcontrollers. Powered by two RH850G4KH cores at 320MHz, it delivers high-performance real-time processing for automotive applications.

The kit includes a 12V power supply with the ASIL-D-compliant RAA271082 PMIC for safe, reliable operation. Debugging is simple with a 14-pin LPD/JTAG debug port. Connectivity options include up to three Ethernet and two CAN FD channels for high-speed communication, and LIN/SENT interfaces for sensor integration. Three Pmod™ connectors support I²C/I2S/SPI expansion for easy prototyping. The kit also features a 128×64 OLED display, LEDs, and a rotary encoder with RGB lighting for interactive feedback.
