8 Summary

The TCAN28xx line of devices are robust mid-range SBCs that have a dense feature set. While initially these devices can come off as overwhelming – the reality is that most of the features are relatively simple to understand as well as implement. This guide is meant to provide a high level understanding of the devices and potential features. After reading this guide a basic understanding of the differences between devices within this family, the devices state machine, main subsystems of the SBC, protection features, and miscellaneous features needs to be understood. This guide does not give exhaustive specification data, nor does this give a in-depth look into the firmware setup – for more information on those topics please see the devices data sheet and the firmware manual. For any remaining questions please reach out to us on E2E where one of our applications engineers can take a look at the inquiry.
