CAN FD 5 Click is a compact add-on board that contains CAN transceiver that supports both CAN and CAN FD protocols. This board features the UJA1162A, a ‘self-supplied’ high-speed CAN transceiver integrating an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant CAN transceiver with Sleep Mode from NXP Semiconductors. It features an under-voltage detection, mode control via a single GPIO pin, remote and local wake-up capability, overtemperature shutdown, and a very low quiescent current in Sleep mode. This Click board™ is suitable for HS CAN networks in automotive and industrial applications, in electric power steering (EPS), tire pressure monitoring system (TPMS), and many more.

CAN FD 5 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

CAN FD 5 Click is based on the UJA1162A, a ‘self-supplied’ high-speed (HS) CAN transceiver integrating an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant CAN transceiver with Sleep Mode from NXP Semiconductors. The UJA1162A provides reliable communication at data rates up to 5 Mbit/s in the CAN FD HS phase, and can be operated in a very low-current Sleep mode with local and bus wake-up capability. A variety of fail-safe and diagnostic features offer enhanced system reliability and advanced power management. The HS CAN transceiver UJA1162A includes a receiver and a transmitter unit, allowing the transceiver to send data to the bus medium and monitors the data from the bus medium at the same time.

The UJA1162A supports five different operating modes: Normal, Standby, Sleep, Overtemp, and Off. Each mode has specific characteristics in terms of quiescent current, data transmission, or failure diagnostic. When the transceiver is in Sleep Mode, the pin routed to the external regulator TLS850B0TBV33 positioned on the back of the Click board™, will be turned off, reducing the power consumption of the external elements. Outputs of those LDOs are routed through the SMD jumpers that can be populated so that the LDOs can be used to power up the mikroBUS™ 3.3V and 5V power rails. However, it should be noted that MikroE does not advise powering up their systems this way - that is why these jumpers are left unpopulated by default.

The CAN FD 5 Click communicates with MCU using the UART interface with the default baud rate of 9600 bps for the data transfer, while the GPIO pins on this Click board™ are used for Sleep Mode control, local wake-up, and an interrupt for CAN transceiver status. CS pin of the mikroBUS™ socket labeled as the SLP can be used for switching between Normal and Stand-By/Sleep Mode by toggling this pin. It also has a Local Wake-Up function routed to the PWM pin on the mikroBUS™, labeled as WAK, which will cause the transition of UJA1162A from Stand-By/Sleep Mode into Normal Mode. Alongside these pins, this Click board™ possesses an interrupt pin labeled as CTS used to indicate to MCU that the transceiver is fully enabled and data can be transmitted and received via the UART TX/RX pins. It is also possible for the user to connect the TX/RX signals of UART communication directly through the UART External header on the left edge of the board.

This Click board™ is designed to be operated with both 3.3V and 5V logic voltage levels that can be selected via VIO SEL jumper. This allows for both 3.3V and 5V capable MCUs to use the UART communication lines properly. However, the Click board™ comes equipped with a library that contains easy to use functions and an example code that can be used as a reference for further development.
