Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified supply chain partners. Confirm that the specific part number matches the required package variant and revision level. Ensure compliance with RoHS directives and relevant automotive quality standards before integration into production designs.

Selection Notes

Select this component when automotive qualification and robust analog capabilities are required within a compact footprint. The integrated CAN and LIN controllers simplify network design by removing external transceiver dependencies. Evaluate memory requirements against the 32 kB Flash limit and ensure the 12-bit ADC resolution meets signal processing needs.
