A board-level thermal analysis is required before committing the part to a hot-running sealed enclosure — the margin disappears faster than the rating suggests."},{"question":"Can I use the internal oscillator for SSI and Microwire slave interfaces at 2 MHz bus speed?","answer":"The internal oscillator on this Stellaris part is 12 MHz rated and provides reasonable accuracy for UART communication. For SSI and Microwire master-mode interfaces at 2 MHz, datasheet-level oscillator tolerance must be verified — a board-level characterization or external crystal is the conservative choice for slave-interface timing margin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S808-IQN50-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/LM3S808-IQN50-C2T when reusing this data.
