1.Function introduction
1.1 Summary
TD5(3)USPCAN series isolated UART/SPI to CAN module is a communication module integrating
microprocessor, CAN transceiver, DC-DC isolated power supply and signal isolation. It has the advantages of
high speed, high isolation, low power consumption and multi-protocol conversion function. It can expand
more CAN interfaces through UART/SPI interface when the CAN control resources on the user master control
board are in short supply.
This product has various functions and is easy to embed. Users can embed in devices with UART/SPI
without changing their hardware devices, so that users can get more CAN communication interfaces and
realize convenient data communication between UART/SPI devices and CAN bus.
