Getting Started - An Example of A Quick EVM Setup

For a quick evaluation with either the 8-pin or 14-pin transceiver options, use the recommended jumper connections in Table 3-2 as a default EVM setup. In this example, PCAN-USB Pro FD adapter is used to enable the CAN connection to a computer via USBCAN frames, sent through J2 (DSUB9) of the EVM.

TCAN5102-Q1 TX FrameFigure 3-4 TX Frame

Figure 3-1 shows the CAN setup for TCAN5102-Q1's default speed of 250 kbps with 50 % sample point. Tx Self Acknoledged is ON, allowing for the ACK bit on the bus. The TCAN5102-Q1 default CAN identifier of 000h was selected and sent with the standard CAN frame format using 3 bytes of the CAN payload as a header - containing 3 fields: operation code (op code), data length and an address. A valid response with ID 001h of 12 bytes of data was received as 48 81 54 43 35 31 30 32. This implies the PCAN Electronic Control Unit (ECU) and the TCAN5102-Q1 CAN FDL Responder are communicating. The ECU transmitted the CAN FD frame and the TCAN5102-Q1 device recognized it as query, responding with ID 001h received as "TCA5102" (encoded in ASCII).

TCAN5102-Q1 EVM shows the TXD, RXD, CANH (yellow) and CANL (blue) traffic. The bottom traces show TXD / RXD toggling, and PCAN-View decodes it into frames. The CAN bursts of differential activity corresponds to the TX frame (ID 000h, 3B) and the RX responder's reply (ID 001h, 12B). TXD shows the transmitted activity only for the first burst whiIe RXD shows activity for both (first, for self acknowledging and secondly, the responder's frame received from the bus).

The EVM may be re-configured as intended, and used with the TCAN5102-Q1 data sheet for additional programming examples (CAN FDL protocol, SPI, UART, I2C and PWM) to communicate with peripherals.

Table 3-1 Recommended Connections
ConnectionTransceiver TypeRecommendations
J18-PinShunt J1.2 low to GND
14-PinLeave J1.2 floating
J2AnyProvides an alternative way to connect CANH, CANL, and GND all through a standard DSUB9 CAN pinout rather than through a regular header.
J314-PinAccess to pin 7 (INH), WAKE, and GND as needed.
J4AnyShunt to implement a 120Ω split termination. Must be used in combination with J6.
J5AnyShunt to implement a 120Ω termination resistor. Along with the split termination (J4 and J6), this allows the simulation of the true CAN bus impedance of 60Ω (that is, two 120Ω terminations in parallel).
J6AnyShunt to implement a 120Ω split termination. Must be used in combination with J4.
J7AnyCAN bus connection (CANH, CANL) and GND. Can be used to send CAN frames via Vector CANoe for example.
J8Any

Shunt to make sure the populated temperature sensor's SCL is connected to CAN FDL Responder.

Or leave floating / disconnected if the GPIO pin (may or may not be configured as SCL) is needed for other connections (also access through J16.1).

J98-PinShunt VIO to P11.
14-PinCan leave floating / disconnected.
J10BothShunt to make sure the populated temperature sensor SDA is connected to CAN FDL Responder.

Or leave floating / disconnected if the GPIO pin (may or may not be configured as SDA) is needed for other connections (also access through J16.2).

J11AnyAccess to all critical CAN FDL GPIO (GPIO0 - GPIO7) and GND for using the CAN FDL IOs externally with test equipment or interfaced to a processor EVM.
J12AnyShunt for CAN FDL Responder CRXD to the CAN transceiver RXD.
J13AnyShunt to supply VDD to CAN FDL.
J14AnyShunt to share VDD, VCC, VIO and 5VLED connections, as needed. As an example, may use a single 5V supply to power all the power supplies needed for the EVM, by supplying VDD with 5V and shunting VDD to VCC, VIO and the 5VLED supply).
J15AnyShunt for CAN FDL Responder CTXD to the CAN transceiver TXD
J16AnyAccess to CAN FDL GPIO9/CS4/SCL, GPIO10/CS5/SDA pins and GND. By default, the GPIO pins are used for driving the TMP117 temperature sensor peripheral.

Can be used for driving the CAN FDL Responder externally with test equipment or interfaced to a processor EVM when the temperature sensor is disconnected via floating J8 and J10.

J17AnyAccess to CAN FDL GPIO11/CS6/PMW0, GPIO12/CS7/PMW1, GPIO8/URXD pins and GND. By default, the GPIO pins are used for driving the multi-color RGB LED D4 peripheral.

If the GPIOs are needed for other peripherals, disconnect from D4 by depopulating R24, R25 and R27 0Ω resistors.

J188-PinDisconnect / float, to allow J1.2 pulled low
14-PinShunt to allow CnSLP of the CAN FDL responder to control nSTB of the transceiver.
J19BothFloat / leave disconnected by default.
J20Ground ClipProvides extra connection to GND.
J2114-PinShunt to connect VBAT and VVSUP.

This bypasses diode D5.
