CAN bus avionics databus interface controller with integrated transceiver introduced by Holt

MISSION VIEJO, Calif., 16 Sept. 2010. Holt Integrated Circuits in Mission Viejo, Calif., is introducing the HI-3110 ARINC 825 -compliant CAN bus controller with integrated transceiver for avionics applications. CAN bus stands for Controller Area Network.

Holt engineers are capitalizing on their expertise in mixed-signal ARINC 429 and MIL-STD-1553 avionics databus solutions to create the ARINC 825 CAN controller for harsh-environment applications. The controller operates in the full military temperature range of -55 to 125 degrees Celsius, and meets ISO 11898-1:2003(E) (CAN protocol) and ISO 11898-5 (CAN transceiver).

The databus interface device communicates with an external microcontroller via a serial peripheral interface (SPI) and has transmit and receive FIFOs that hold as many as eight CAN frames each. The HI-3110 includes monitor mode, loopback mode, and a low-power sleep mode. Automatic wake-up from sleep mode is also possible.

The HI-3111 is a digital-only version (no transceiver) for applications with an external transceiver. All device variants are available in an 18-pin SOIC package or a compact 44-pin QFN. For more information contact Holt online at www.holtic.com.
