SJA1000T Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the SJA1000T?
  The SJA1000T can operate from -40°C to 125°C, but the recommended operating temperature range is -20°C to 85°C for optimal performance.
• How do I configure the SJA1000T for CAN FD mode?
  To configure the SJA1000T for CAN FD mode, you need to set the CAN_MODE register to 0x01 and the CAN_BTR register to 0x03. Additionally, you need to set the bitrate to 500 kbps or higher and enable the CAN FD protocol using the CAN_CTRL register.
• What is the maximum number of nodes that can be connected to a single SJA1000T?
  The SJA1000T can support up to 128 nodes on a single bus, but the actual number of nodes that can be connected depends on the bus topology, cable length, and other system parameters.
• How do I implement a watchdog timer on the SJA1000T?
  The SJA1000T has a built-in watchdog timer that can be enabled using the WDT_CTRL register. You need to set the watchdog timer period and enable the timer using the WDT_CTRL register. The watchdog timer will reset the device if it does not receive a watchdog feed within the set period.
• What is the minimum input voltage required for the SJA1000T?
  The minimum input voltage required for the SJA1000T is 4.5V, but it is recommended to use a minimum input voltage of 4.75V for optimal performance.
