HI-3111PSHF

The HI-3111H is a standalone Controller Area Network (CAN) controller optimized for use in high temperature avionics applications. The device is capable of operating at extended temperature ranges of -55°C to 175°C and provides a complete, integrated, cost-effective solution for high temperature avionics applications implementing the CAN 2.0B specification. It can be configured to comply with both the ARINC 825 (General Standardization of CAN Bus Protocol for Airborne Use) and CANaerospace standards. The HI-3111H is capable of transmitting and receiving standard data frames, extended data frames and remote frames. The device interfaces with an external host via a Serial Peripheral Interface (SPI), resulting in minimal board space. The HI-3111H provides the optimum solution for high temperature avionics 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).
