[原創(chuàng)] MicrochipCAN LIN CAN－FD汽車網(wǎng)絡(luò)開(kāi)發(fā)方案

microchip公司的CAN LIN CAN-FD汽車網(wǎng)絡(luò)開(kāi)發(fā)板采用8位,16位和32位Microchip MCU系列,提供低成本模塊化平臺(tái),用于CAN, LIN, CAN-FD網(wǎng)絡(luò)開(kāi)發(fā).具有四個(gè)mikroBUS™插座,支持CAN和CAN-FD. 7-30V DC電源輸入給整個(gè)板提供+3.3V和+5V穩(wěn)壓電源.本文介紹了汽車網(wǎng)絡(luò)開(kāi)發(fā)板主要特性,框圖和電路圖.

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.
