ARINC 825 Compliant CAN Controller Features Integrated Transceiver

Fri, 09/10/2010 - 6:23am
Holt Integrated Circuits today introduced the world's first ARINC 825 compliant CAN controller with an integrated transceiver. The device meets the requirements of both ISO 11898-1:2003(E) (CAN protocol) and ISO 11898-5 (CAN transceiver).

Controller Area Network (CAN) devices have become a popular data bus solution in the avionics industry, most notably since the release of the ARINC 825 specification in November 2007, which standardized the use of CAN in avionics applications. Holt has leveraged its expertise in providing mixed signal ARINC 429 and MIL-STD-1553 solutions and produced the first ARINC 825 compliant CAN controller with an integrated transceiver. The device is capable of operating in the temperature range -55oC to +125oC.

The HI-3110 provides the most compact and reliable implementation of CAN in the avionics industry today, providing an easy-to-use host SPI interface and connecting directly to the CAN bus via the internal transceiver said Anthony Murray, Director of Business Development at Holt.

The device communicates with an external microcontroller via a Serial Peripheral Interface (SPI) and has transmit and receive FIFOs that hold up to eight CAN frames each. The HI-3110 has numerous modes of operation, including monitor mode, loopback mode and a low-power sleep mode. Automatic wake-up from sleep mode is also possible. Other features include 8 maskable ID filters with filtering on the first two data bytes, permanent dominant timeout protection, +/-58V short circuit capability on CANH, CANL and SPLIT pins and a transmit history FIFO.

The HI-3111 is a digital-only version (no transceiver) which may be used in applications where an external transceiver is desired. All device variants are available in an 18-pin SOIC package or a compact 44-pin QFN.

Samples of HI-3110 are available immediately, along with a demonstration board kit and example software.
