Microcontrollers Procurement Notes

Verify the lifecycle status as NRND (Not Recommended for New Designs) before procurement. Confirm that the specific suffix matches the required pinout and electrical characteristics. Ensure compatibility with existing development tools such as the EKS-LM3S8962 kit. Check for moisture sensitivity levels and storage requirements. Validate that the component meets RoHS compliance standards for the target market.

Microcontrollers Selection Notes

Select this model when both Ethernet and CAN interfaces are required in a single MCU. The 256 kB flash size suits complex firmware applications. The integrated PHY reduces external component count. Consider the 50 MHz speed for real-time processing needs. Evaluate the 100-pin package for sufficient I/O availability. Compare against other Stellaris variants if lower memory or different interface combinations are sufficient.
