3 Description
The SN55HVD233-SP is used in spacecraft applications employing the controller area network (CAN) serial communication physical layer in accordance with the ISO 11898 standard. As a CAN transceiver, the device provides transmit and receive capability between the differential CAN bus and a CAN controller, with signaling rates up to 1 Mbps.
Designed for operation in especially harsh radiation environments, the SN55HVD233-SP features cross-wire, overvoltage, and loss of ground protection to ±16 V, overtemperature (thermal shutdown) protection. This device operates over a wide –7-V to 12-V common mode range. This transceiver is the interface between the host CAN controller on the microprocessor, FPGA, or ASIC, and the differential CAN bus used in satellite applications.
