December 16, 2019 – Mouser Electronics is now stocking the TCAN4550 and TCAN4550-Q1 Controller Area Network with Flexible Data Rate (CAN FD) controllers from Texas Instruments. Supporting data rates of up to 5 Mbits per second (Mbps) with up to 18 MHz SPI clock speed, the TCAN4550 devices are the industry’s first system basis chip to integrate a controller and transceiver for CAN FD. The highly integrated controllers are ideal for use in building automation, industrial transports, and factory automation, and the TCAN4550-Q1 version is AEC-Q100 qualified for use in automotive applications.
The TI TCAN4550 controllers, available from Mouser Electronics, deliver differential transmit capability to the bus and differential receive capability from the bus. The controllers boast wide CAN BUS operating ranges, including ±42 V bus fault protection and ±12 V common mode. The chips provide an interface between the system processor and the CAN bus using a serial peripheral interface (SPI), offering support for both CAN FD and classical CAN. Featuring multiple operating modes, including standby and sleep, the controllers offer low power consumption through the use of wake and inhibit features. Capable of supporting the bandwidth and data flexibility requirements of in-vehicle networks, the controllers can implement a CAN FD interface on a system using the SPI bus of nearly any microcontroller.
The TCAN4550 controllers are supported by the TCAN4550EVM evaluation module, which can be connected to any microcontroller or SPI controller with an I/O voltage of 3.3 V or 5 V using a standard interface header. Featuring an EMC-filtered and polarity-protected supply voltage, the evaluation module is capable of operating using an external voltage of 6 V to 24 V.
