Hello. Today I'd like to talk to you about CAN FD implementations and how the TCAN4550-Q1 CAN FD System Basis Chip, or SBC, can add this advanced functionality to your automotive or industrial design quickly and easily.
With the release of the can FD specification, users can experience enhance bus optimization with the support of 64-byte payloads and up to 5 megabit per second data rates. As the market rapidly adopts this next generation bus, designers find that many microcontrollers do not support CAN FD compatible controllers. This limits their ability to support CAN FD.
Although CAN FD and classic CAN support coexistence, classic CAN is not forward compatible to CAN FD. The TCAN4550-Q1 bridges microcontrollers lack of CAN FD controllers by integrating a fail-safe CAN FD transceiver and CAN FD controller into a small single-chip solution that can communicate to your existing or new microcontroller over the SPI bus.
Designers now have the option to add the TCAN4550-Q1 to their existing controller based architecture for faster time to market or by utilizing a smaller and lower cost microcontroller without the integrated classic CAN controller. The TCAN4550-Q1 also has watchdog support, which allows designers to eliminate this feature from the microcontroller or to use with additional solution components.
If the microcontroller supports a CAN FD controller, the TCAN4550-Q1 solution can also be used to add additional CAN FD lanes to applications such as gateways. The device supports a self-powered CAN FD transceiver via an internal LDO which supports up to 70 milliamps output for powering an external microcontroller, sensor, or other component. When combined with the supported wake inhibit features, applications can control node power to help deliver a sub-100 microamp power-consuming solution during sleep mode.
The device is offered in a small 20-pin QFN package, supporting wettable flanks for optimal automated optical inspection. Measuring 4.5 millimeters by 3.5 millimeters, the solution utilizes less board space than standard SOIC packaged CAN transceivers.
