3.1.12.1 CAN FDL Responder Configurations

The CAN FDL EVM has footprints on the PCB for the installation of various filtering and protection options to evaluate the TCAN1052-Q1 CAN network topology requirements if the EVM is being used as a CAN node.

Each digital CRXD, CTXD and CnSLP input or output pin has footprints allowing for series current-limiting resistors (default populated with 0Ω) and shunts to connect to the CAN transceiver RXD, TXD and nSTB (or STB) pins respectively. CRXD of the CAN FDL Responder is an input incoming from the CAN transceiver RXD output, CTXD of the CAN FDL Responder is an output feeding into the CAN transceiver TXD input and CnSLP of the CAN FDL Responder is an output feeding into the CAN transceiver nSTB input. CnSLP is high by default (in normal mode), placing the CAN transceiver nSTB to normal mode. Note that, this is true for 14-pin transceivers with nSTB and the polarity is flipped for 8-pin transceivers with STB. When using an 8-pin transceiver, leave J18 open / floating / disconnected and use J1.2 header to pull STB pin low for normal operation.
