The HI-3112 is a standalone Controller Area Network (CAN) controller with built in transceiver. The device provides a complete, integrated, cost-effective solution for avionics applications implementing the CAN 2.0B specification and can be configured to comply with both the ARINC 825 (General Standardization of CAN Bus Protocol for Airborne Use) and CANaerospace standards. The HI-3112 is capable of transmitting and receiving standard data frames, extended data frames and remote frames. The internal transceiver allows direct connection to the CAN bus without using external components and coupled with the host Serial Peripheral Interface (SPI), results in minimal board space. The HI-3112 provides the optimum solution for applications where minimum host (MCU) overhead is required, filtering unwanted messages using a maskable identifier filter and storing up to 8 messages in the receive FIFO. A flexible interrupt scheme allows real time servicing of the FIFO by the host, if required. Transmissions are handled using an 8 message transmit FIFO. A Transmit Enable pin can be used by the host to initiate a transmission. The device also provides monitor or listen-only mode, low power sleep mode, loopback mode for self-test and a re-transmission disable capability (necessary to implement TTCAN protocol).


The HI-3112 provides an option of a CLKOUT pin instead of a SPLIT pin, which may be used as the main system clock or as a clock input for other devices in the system.

The device is available in industrial and full extended temperature ranges, with a “RoHS compliant” lead-free option.
