TI TCAN4550 system basic chip analysis

The design of electronic products is inseparable from a variety of chips. Mouser Electronics, an electronic component distributor that focuses on introducing new products and providing large inventories, will stock Texas Instruments (TI)'s TCAN4550 and TCAN4550-Q1 CAN from now on. FD controller.

The TCAN4550 device supports data transfer rates up to 5Mbps and SPI clock speeds up to 18 MHz. It is the industry's first system basis chip to integrate a CAN FD controller and transceiver. These highly integrated controllers are suitable for building automation, industrial transportation and factory automation, and the TCAN4550-Q1 version is AEC-Q100 certified and suitable for automotive applications.

The TI TCAN4550 controller supplied by Mouser Electronics has differential transmit capabilities to the bus, and differential receive capabilities from the bus. These controllers feature a wide CAN bus operating range, including ±42 V bus fault protection and ±12 V common mode. These chips use the Serial Peripheral Interface (SPI) to provide an interface between the system processor and the CAN bus, supporting both CAN FD and Classic CAN. The TCAN4550 controller has multiple operating modes, including standby and sleep, and achieves low power consumption through the use of wake and inhibit functions. These controllers are capable of supporting the bandwidth and data flexibility requirements of in-vehicle networks, using the SPI bus of virtually any microcontroller to implement the CAN FD interface on the system.

The TCAN4550 controller also has a companion TCAN4550EVM evaluation module, which can be connected to any microcontroller or SPI controller with I/O voltages of 3.3 V or 5 V using standard interface plugs. The TCAN4550EVM has an EMC filtered and polarity protected supply voltage and is capable of operating with external voltages from 6 V to 24 V. The above is the TI TCAN4550 system basic chip launched by Mouser that integrates CAN FD controller and transceiver. I hope it will be helpful to everyone when choosing.
