Microchip Technology's MCP2517FD-H/JHA: CAN FD Controller with SPI Interface

The MCP2517FD-H/JHA is a high-performance, stand-alone CAN (Controller Area Network) FD (Flexible Data-rate) controller developed by Microchip Technology. It is a crucial component for applications requiring reliable data communication with high data rates and robust error management. This product is designed to interface with microcontrollers (MCUs) that do not have a built-in CAN FD controller via the Serial Peripheral Interface (SPI).

The MCP2517FD-H/JHA supports both the traditional CAN 2.0B protocol at speeds up to 1 Mbps and the newer CAN FD protocol that allows for data rates up to 8 Mbps. This flexibility makes it an ideal choice for automotive and industrial applications where higher bandwidth and more flexible data rates are required. It is also well-suited for other applications in control systems, such as medical equipment, home automation, and embedded electronics.

This product comes in a 14 x 14 mm VQFN package that is both space-efficient and suitable for automated assembly processes, making it a practical choice for modern PCB designs. Its extended temperature range of -40°C to +125°C ensures reliability and performance in harsh environments.

The MCP2517FD-H/JHA features an array of robust functionalities, including:

• Up to 32 FIFOs for flexible message management.
• An advanced set of filters for incoming messages, allowing for precise control over the messages the application processes.
• Two receive queues for high priority messages to ensure critical data is processed quickly.
• Time-stamping for messages, which is essential for applications that require precise timing analysis.
• Secondary sample point and Delay Compensation to enhance data integrity and reliability.

The device also features a deep 128-byte FIFO for each transmit and receive channel, which helps to manage large bursts of data and reduce the overhead on the host MCU. With its integrated VREG, the MCP2517FD-H/JHA simplifies power management by providing the necessary voltages internally.

For developers, Microchip provides extensive support in the form of datasheets, application notes, and a suite of development tools to streamline the design process. The MCP2517FD-H/JHA is not just a piece of hardware; it is a solution supported by a leader in microcontroller and analog semiconductors, ensuring long-term availability and support for your products.
