CAN FD Click is a add-on board based on TLE9252V CAN network transceiver, designed for HS CAN networks up to 5 Mbit/s in automotive and industrial applications. As an interface between the physical bus layer and the CAN protocol controller, the TLE9252V drives the signals to the bus and protects the microcontroller against interferences generated within the network. Given all the features its components offer, the CAN FD Click is best used for for infotainment applications, cluster modules, radar applications and HVAC.

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

CAN FD Click features TLE9252V high speed CAN network transceiver from Infineon. HS CAN is a serial bus system which connects microcontrollers, sensors and actuators for real-time control applications. The TLE9252V supports both Bus Wake-up Pattern (WUP) functionality and Local Wake-up, as well as CAN Flexible data rate transmission up to 5Mbit/s. Additionally, the TLE9252V supports CAN Flexible data rate (CAN FD) transmission up to 5 Mbit/s The TLE9252V also has an integrated over temperature detection to protect the TLE9252V against thermal overstress of the transmitter.

The CAN FD Click supports five different Modes of operation. Each mode with specific characteristics in terms of quiescent current, data transmission or failure diagnostic. For the mode selection the digital input pins EN and STB are used.

• Normal-operating mode - all functions of the TLE9252V are available and the device is fully functional.
• Receive-only mode - the transmitter is disabled and the receiver is enabled.
• Stand-by Mode is a low power mode of the TLE9252V and the transmitter and the receiver are disabled.
• Sleep Mode - is a low power mode of the TLE9252V. In Sleep Mode the current consumption is reduced to a minimum while the device is still able to detect a Wake-Up Pattern on WKE pin.
• Go-to-Sleep command- is a transition mode allowing external circuitry like a microcontroller to prepare the ECU to go to Sleep Mode.

The HS CAN transceiver TLE9252V 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 by suing two wires. The TLE9252V converts the serial data stream which is available on the transmit data input TxD, into a differential output signal on the CAN bus, provided by the CANH and CANL pins.

Given all the features its components offer, the CAN FD Click is best used for for infotainment applications, cluster modules, radar applications and HVAC. The onboard SMD jumper labeled as the VIO SEL is used to select which voltage rail will be used as the logic voltage level. It offers voltage selection between 3.3V and 5V so that the Click board™ can be interfaced with both the 3.3V and 5V capable MCUs. The two UART wires (RX and TX) can also be connected directly through two pins on the left edge of the board. With R5 and R6 jumpers populated alows you to use Click board™ with standard 12V battery connected on battery pads at right side of board.
