Frequently asked questions
Does the LM3S811-EQN50-C2 come in tape-and-reel or tray packaging, and what are the minimum order quantities?
The LM3S811-EQN50-C2 ships in Tray packaging — not tape-and-reel — confirmed against entry. Minimum order quantities and lot size for tray-packaged parts vary by distributor and stock lot; confirm against the specific offer before committing a panel-build quantity.
How do I program and debug the LM3S811-EQN50-C2?
Stellaris MCUs use a JTAG debug interface (standard 20-pin or 14-pin header) for programming and real-time debugging. The standard toolchain pairing is IAR Embedded Workbench for ARM (EWARM) or Keil MDK-ARM — both have Stellaris device packs historically validated against TI's StellarisWare firmware library. Exact toolchain version compatibility depends on the StellarisWare revision and should be confirmed against the specific firmware bundle in use on the existing board.
