[原创] MicrochipCAN LIN CAN－FD汽车网络开发方案

microchip公司的CAN LIN CAN-FD汽车网络开发板采用8位,16位和32位Microchip MCU系列,提供低成本模块化平台,用于CAN, LIN, CAN-FD网络开发.具有四个mikroBUS™插座,支持CAN和CAN-FD. 7-30V DC电源输入给整个板提供+3.3V和+5V稳压电源.本文介绍了汽车网络开发板主要特性,框图和电路图.

The CAN, LIN, CAN-FD Automotive Networking Development Board provides alow-cost modular platform for CAN, LIN, CAN-FD network development using 8-bit,16-bit, and 32-bit Microchip microcontroller families. It features four mikroBUS™headers to accommodate a variety of plug-in Click™ Board combinations for LIN, CAN,and CAN-FD development. The Automotive Networking Development Board supportsCAN and CAN-FD natively. The CAN digital connection from the microcontrollerconnects to the TX/RX connection on the mikroBUS™ header. This connectionsupports the CAN and CAN-FD Transceiver Click™ boards without having to lose themicrocontroller UART connection to the other mikroBUS™ headers.
