- Sensor nodes in automotive networks needing LIN transceiver functionality
Procurement Notes
Verify the specific ordering suffix and revision level against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm that the VQFN-48 package dimensions match your PCB footprint exactly. Check for any recent lifecycle status updates or recommended alternative part numbers directly from Microchip Technology before finalizing procurement plans.
Selection Notes
Select this component when a combined MCU and LIN transceiver solution is required to reduce board space and component count. The integrated voltage regulator simplifies power design for 5V to 28V automotive systems. Ensure the 16 kB Flash and 4 kB RAM meet application code and data storage needs. Verify that the 48 MHz processing speed is sufficient for the intended LIN stack and application logic execution.
Part Context
This part belongs to the SAM HA1G series, which targets automotive LIN network applications. It combines standard microcontroller capabilities with specialized automotive communication interfaces. The integration of the LIN transceiver allows for direct connection to vehicle wiring harnesses without external PHY components.
Replacement Considerations
