Developed by Bosch,  CAN with Flexible Data-Rate (CAN FD) is an extension to the original CAN protocol as specified in ISO 11898-1, which responds to increased bandwidth requirements in automotive networks. CAN FD has the support of semiconductor chip manufacturers and end users alike, with Infineon, NXP, Daimler and GM among the companies behind the new standard.

A  standard CAN network is limited to 1 MBit/s, with a maximum payload of 8 bytes per frame. CAN FD increases the effective data-rate by allowing longer data fields – up to 64 bytes per frame – without changing the CAN physical layer. CAN FD also retains normal CAN bus arbitration, increasing the bit-rate by switching to a shorter bit time only at the end of the arbitration process and returning to a longer bit time at the CRC Delimiter, before the receivers send their acknowledge bits. A realistic bandwidth gain of 3 to 8 times what’s possible in CAN will particularly benefit flashing applications.

We at Copperhill Technologies are preparing a new product release, namely the MCP2517FD CAN-Bus FD Board for Raspberry Pi 3. This PiCAN FD board provides CAN-Bus FD capabilities for the Raspberry Pi. It uses the Microchip MCP2517FD CAN controller in combination with the MCP2562FD CAN transceiver. Connection is established via DB9 or 3 way screw terminal.

Features

• Microchip MCP2517FD CAN Controller
• Microchip MCP2562FD CAN transceiver
• Arbitration Bit Rate u pto 1Mbps
• Data Bit Rate upto 8Mbps
• CAN FD Controller modes
  • Mixed CAN 2.0B and CANFD mode
  • CAN 2.0B mode
• Conforms to ISO 11898-1:2015

The board is currently in production, and we are waiting for more information from the manufacturer in regards to timing and pricing. In the meantime, have a look at our CAN FD Breakout Board With SPI Interface.

SAE J1939 to Bluetooth Gateway With 9-Pin Deutsch Connection Cable

The  jCOM.J1939.BT gateway is a high-performance, low-latency, wireless vehicle network adapter for SAE J1939 applications. It allows any host device with a Bluetooth COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network. An SAE J1939 cable, suited for a 9-pin Deutsch connection, is included with the gateway.

The gateway supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments.
