Texas Instruments offers a broad portfolio of high-speed controller area network, CAN, transceivers compatible with the ISO 11898-2:2016 standards. These include 5-V V_CC only, 3.3-V V_CC only, 5-V V_CC with I/O level shifting, and galvanic-isolated CAN transceivers. These CAN transceiver families include product mixes with varying features such as low-power standby modes with and without wake up, silent modes, sleep modes, loop back, and diagnostic modes.

The TI TCAN1043AEVM helps designers evaluate the operation and performance of the TCAN1043A-Q1 CAN FD transceiver in the SOT package. The ability to perform system-level evaluation using the V_IO, EN, INH, nSTB, V_SUP, WAKE, and nFAULT pins can be realized on the EVM. It also provides bus termination, bus filtering, and protection concepts. Use the TCAN Evaluation Module to evaluate TI's 8-pin CAN and CAN FD transceiver families.

The TCAN1043A-Q1 EVM has simple connections to all necessary pins of the CAN transceiver device, and jumpers where necessary to provide flexibility for device pin and CAN bus configuration. There are test points (loops) for all main points where probing is necessary for evaluation such as GND, V_CC, TXD, RXD, CANH, CANL, EN, nFAULT, and WAKE. The EVM supports many options for CAN bus configuration. It is pre-configured with two 120-Ω resistors connected on the bus via jumpers: a single resistor is used with the EVM as a terminated line end (CAN is defined for 120-Ω impedance twisted pair cable) or both resistors in parallel for electrical measurements representing the 60-Ω load the transceiver detects in a properly-terminated network (that is, 120-Ω termination resistors at both ends of the cable). If the application requires split termination, TVS diodes for protection, or a Common Mode (CM) Choke, the EVM has footprints available for this via customer installation of the desired components. Figure 1-1 shows the EVM board image.
