Interface card

With four isolated CAN channels

Acropack CAN modules from Acromag (USA) target defense and avionics applications with PCIe mezzanine supporting Arinc 825 and CAN aerospace standards.

The AP560 module provides four independent, isolated CAN channels. Each channel has a H13111 CAN controller by Holt paired with a galvanic isolated ADM3053 transceiver by Analog Devices. Designed for defense and avionics applications, the interface board is configurable to comply with Arinc 825 and CAN aerospace standards. A variety of carrier cards are available to host up to four Acropack I/O modules on PCI Express, VPX, or XMC computer platforms.

This module offers a solution for interfacing isolated CAN signals in aerospace, military, and other applications implementing the Classical CAN identifier base frame format (11-bit IDs) and Classical CAN identifier extended frame format (29‑bit IDs). 1000‑V isolation separates the four channels from each other and from the host. The controller is ISO 11898‑5 compliant for Part A (11‑bit) and Part B extended (29‑bit) arbitration ID with programmable bit rates up to 1 Mbit/s.

“With this addition of a CAN interface solution, the Acropack I/O line can now accommodate an even broader range of applications,” stated Robert Greenfield from Acromag. “System developers are able to mix CAN modules with other Acropack models on a single board for any mix of analog I/O, digital I/O, serial communication, or FPGA processing functions.”

Acropack mezzanine modules improve on the mini PCI Express architecture by adding a down-facing 100‑pin connector that routes the I/O through a carrier card without any loose internal cabling. Carrier cards in PCIe, VPX, and XMC formats let combine up to four I/O function modules from more than 25 available models in a single computer slot. Software tools support embedded applications running on Linux, Windows, or VxWorks operating systems.
