SI32261CFB20BC0EVB Working Principle

The SI32261CFB20BC0EVB is based on the SI32261A transceiver of Silicon Laboratories. The SI32261A includes a CAN physical layer transceiver for single-wire CAN (secured) systems and adds an extra CAN bus to connect with TI’s integrated CAN bus microcontroller. By using the evaluation board, users can easily evaluate the SI32261A’s performance and its compatibility with host microcontroller. The board comes with two identical connectors for differential (Bus A/Bus B) CAN connection, each with a width of three pins. With one connector on the evaluation board, the two pins on the left hand side are connected to CANH (high potential) and the pin on the right hand side is connected to CANL (low potential). With the other connector, the two pins on the right hand side are connected to CANH and the pin on the left hand side is connected to CANL. Consequently, the third CAN will receive the state of the CAN bus from Bus A (CANHI and CANLO) and transfer it to Bus B at the same time. In addition, the SI32261A transceiver incorporates protection features such as undervoltage lockouts (UVLO) and bus overload functions which provide a safer operation. The 3.3V power supply is selectable among different voltage levels, and the current consumption can vary between 0.3mA to 1.3mA.

Conclusion

In conclusion, SI32261CFB20BC0EVB is a powerful evaluation and demonstration board which is used to test SI32261A transceiver’s performance for SAE J1939 applications. The board supports an extended temperature range from -40℃ to +90℃, and has built-in protection features, such as undervoltage lockouts and bus overload functions. Together with its easy-to-use platform, the SI32261CFB20BC0EVB makes system development time shorter and cost-efficient.
