Microchip公司的ATA6570是单独可用具有局部网络的高速控制器区域网络(CAN)收发器,完全和ISO 11898-2, ISO11898-5, ISO11898-6, ISO/DIS 11898-2 (2016)以及SAEJ2962-2兼容,标准CAN数据速率高达1Mbps,CAN FD数据速率高达5Mbps(CAN FD),4Mbps SPI接口,能直接和3.3V-5V MCU接口,主要用在汽车环境.本文介绍了ATA6570主要特性,框图,以及ATAB657XA开发板主要特性,电路图,材料清单和PCB设计图.
The Atmel® ATA6570 is a standalone high speed CAN transceiver that interfaces a Controller Area Network (CAN) protocol controller and the physical two wire CAN bus designed for high speed CAN applications in the automotive environment.
It provides local and enhanced remote wake-up capabilities and is available in a SO14 package. The Atmel ATA6570 has a very low power consumption in Standby and Sleep Mode. Beside local wake-up via WAKE and remote wake-up pattern according to ISO 11898-5, ATA6570 additionally supports ISO11898-6 compliant CAN partial networking. A CAN frame decoder evaluates the bus traffic and checks for a matching frame, that has being configured into registers via the SPI. The device is able to keep the complete ECU in a low power mode even when bus traffic is present until a valid wake-up frame is received. It also features a watchdog and a Serial Peripheral Interface (SPI).
The Atmel ATA6570 is a CAN-FD device and can be easily configured via the SPI as Non-FD (meaning only for Classical CAN), CAN FD silent, CAN FD passive or as CAN FD active device, in order to fulfill the corresponding application requirements.
The VIO pin allows the automatic adjustment of the I/O levels to the I/O level of the connected microcontroller.The SPI interface controls the device and provides status and diagnosis information to the Host MCU.All these features make the Atmel ATA6570 an excellent choice for high speed CAN networks, especially in applications where nodes are always connected with the battery but are only activated when they are really needed in the application.
