The SJA1000 can support up to 32 nodes in a CAN bus network, but this number can be limited by the physical layer and the specific application requirements.
The SJA1000 has built-in error detection and fault confinement mechanisms, including bit error detection, stuff error detection, and CRC error detection. It also has a bus fault detection mechanism that can detect and report bus faults, such as bus shorts or opens.
Yes, the SJA1000 can operate in a multi-master configuration, where multiple nodes can transmit data on the CAN bus simultaneously. However, this requires careful design and implementation to avoid bus conflicts and ensure reliable data transmission.
The SJA1000 supports data transfer rates up to 1 Mbps, which is the maximum specified by the CAN 2.0B protocol.
The SJA1000 has a built-in power-on reset (POR) circuit that resets the device when power is applied. It also has a power-down mode that can be controlled by the host microcontroller to reduce power consumption when the device is not in use.
