Page 9: Chapter 1 Introduction
Chapter 1 Introduction Chapter 1 Introduction The V850E2/Px4 Starter Kit is Renesas’ new evaluation platform for the latest 32-bit microcontroller V850E2/Px4. The board is designed for engineers starting software development with the V850E2/Px4 device e.g. with the Renesas’ AUTOSAR compliant MCAL. -
Page 10: Chapter 2 General Information
The 1.2 V overvoltage LED is an indicator for overvoltage on the 1.2 V line, thus the non-glowing of this LED is not a malfunction. The V850E2/Px4 is available for two different I/O voltages, 3.3 V or 5 V. As the Starter Kit Board supports both types, the I/O voltage can be chosen by CN18. -

For additional information please consult the Data Sheet of the reset controller (Texas Instruments, TLC7701ID). 2.4 Nexus connection The 20-pin Nexus debug cable from Renesas’ debug tool (e.g. MiniCube) can be connected to the Nexus Connector on the board. 2.5 E1 connector The board is equipped with a 14-pin connector. -
Page 12: Communication
Chapter 3 Communication Chapter 3 Communication The Starter Kit Board is equipped with five D-Sub connectors, mounted at the left and right side. On the left side you can find the two female connectors for FlexRay and one shared male connector for UART and LIN. On the right side the two female connectors for CAN are located. -

Chapter 3 Communication 3.4 CSI interface The mounted CSI (SPI) interface provides access to two instances of each kind of CSI (CSIG and CSIH) and four chip select signals. Figure 2 CSI 20-pin interface Note The chip select signals of the two CSIH instances are multiplexed to the same port, so CSIH1CSx means also chip select signal for CSIH0. -
