Microchip introduced their SAMC21N Xplained Pro Evaluation Kit, a development board for its ARM-based MCUs featuring CAN FD connectivity. The products are equipped with the company’s CAN transceivers qualified for 5 Mbit/s.
The evaluation kit is supported by the Studio integrated development platform. It includes an on-board Embedded Debugger, eliminating the need for external tools to program or debug the ATSAMC21N18A micro-controller. The kit offers additional peripherals to extend the features of the board and ease the development of custom designs. The MCU on-chip two-channel CAN FD module is connected to two CAN FD transceivers supporting bit-rates up to 5 Mbit/s. The CAN FD interface comply with ISO 11898-1:2015, even if the data sheet and handbook reference the Bosch specification (non-ISO CAN FD).
Additionally, the evaluation board provides a LIN transceiver as well as SPI, I2C, and USB connectivity. There are also four general-purpose I/O lines and a virtual COM port (CDC). Furthermore the Cortex-M0+ MCU has multiple timers, a 12-channel event system, and a 12-channel direct memory access controller.
CAN FD Breakout Board With SPI Interface
The CAN FD breakout board utilizes the Microchip MCP2517FD CAN FD controller in combination with the MCP2562FD CAN Bus transceiver.
The CAN connection is available via the DB9 connector. The connector can be configured for different pinout, either for ODB-II or standard CAN.
