Binary compatibility is not maintained across the Stellaris-to-Tiva transition."},{"question":"Does the 8KB RAM fit a FreeRTOS application with a CANopen stack?","answer":"The 8KB RAM ceiling is tight. A FreeRTOS heap consuming ~6KB combined with a CANopen stack will approach the boundary under typical runtime conditions — memory budget analysis against the actual compiled binary is required before committing the line."},{"question":"How do I source the LM3S828-EGZ50-C2T given the EOL-hot status?","answer":"Open an RFQ immediately to identify available channel stock and confirm lot traceability. The eol_hot window means allocation can close without advance notice — a documented last-time-buy quantity should be agreed with your supplier before the window resolves further."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S828-EGZ50-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S828-EGZ50-C2T when reusing this data.
