The MAC does not include an internal PHY. If your board already has the PHY populated, the MAC section is a direct signal-level drop-in."},{"question":"What is the lead time and how do I source this part?","answer":"With an Obsolete status there is no normal lead time through authorized distribution. Sourcing is via independent distributor or surplus channel. Request traceability documentation (certificate of conformance, authorized supply chain) to confirm authenticity, and be aware that broker-channel pricing on obsolete TI ARM parts carries a significant premium and lead-time uncertainty."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9U92-IBZ80-A1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9U92-IBZ80-A1T when reusing this data.
