Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific ordering suffix matches the required package and temperature grade. Request the latest datasheet revision to ensure alignment with current manufacturing specifications. Check for RoHS compliance documentation as indicated in the product summary.

Selection Notes

Select this model when an 8051-compatible architecture with integrated power stages is required. Ensure the application utilizes the LIN interface for communication needs. Verify that the 48 kByte Flash capacity meets firmware storage requirements. Confirm that the VQFN-48-29 package dimensions fit the PCB layout constraints.

Part Context

This component belongs to the TLE983x family of automotive microcontrollers designed for embedded power applications. It shares the XC800 core architecture with other devices in the series but offers specific peripheral configurations including 48 kByte Flash and integrated high/low-side switches tailored for automotive load control.

Replacement Considerations

Consult official Infineon cross-reference documents for verified substitutes within the TLE983x family. Ensure any replacement maintains compatibility with the XC800 instruction set and pinout configuration. Verify that alternative parts support the same voltage range and automotive qualification standards.
