CAN FD 4 Click Board™

Product Code: MIKROE-4107

How Does The CAN FD 4 Click Board™ Work? The CAN FD 4 Click Board™ is based on the NCV7344D10R2G, is a complete CAN protocol controller and the physical bus, from ON Semiconductor. The Click board™ guarantees additional timing parameters to ensure robust communication at data rates beyond 1 Mbps to cope with CAN flexible data rate requirements (CAN FD). These features make the CAN FD 4 Click an good choice for all types of high speed - controller area network (HS−CAN) networks. The CAN FD 4 Click Board™ provides two operation modes, these modes are selectable pin CS. First option is normal mode (when CS pin is LOW), where the transceiver is able to communicate via the bus line.The signals are transmitted and received to the CAN controller via the pins TxD and RxD. The slopes on the bus lines outputs are optimized to give low EME. Second option is when CS pin is HIGH, and the CAN FD 4 Click is in Standby mode. In standby mode both the transmitter and receiver are disabled and a very low−power differential receiver monitors the bus lines for CAN bus activity.When a wake−up request is detected by the low−power differential receiver, the signal is first filtered and then verified as a valid wake signal after a time period of twake_filt, the RxD pin is driven low by the transceiver (following the bus) to inform the controller of the wake−up request.

High speed CAN (HS CAN) is a serial bus system that connects microcontrollers, sensors and actuators for realtime control applications. Compatible with ISO 11898-2 (2016) describes the use of the Controller Area Network (CAN) within road vehicles. According to the 7-layer OSI reference model the physical layer of a HS CAN bus system specifies the data transmission from one CAN node to all other available CAN nodes within the network. The CAN transceiver is part of the physical layer. The CAN FD 4 Click Board™ is designed to be operated only with 5V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 3.3V.
