It is not 5V-tolerant, so a direct 5V supply will damage it. Check the board's regulator before swapping onto a legacy 5V design."},{"question":"What is the real thermal headroom for this part in an enclosed panel at 85°C ambient?","answer":"TA-rated to 105°C, so 20°C of margin remains at 85°C ambient — which is adequate for most enclosed industrial panels. The 1.8V to 3.6V supply constraint matters more at elevated temperature: stay within the lower rail boundary, especially with 34 I/O switching simultaneously at 24MHz."},{"question":"Is there a second source or drop-in replacement for the MSP430FR2155TDBTR?","answer":"No official second-source or successor order code is cited in this record. The MSP430FR2155TDBTR base product number is the authoritative reference; any cross-reference to a pin-compatible alternate requires TI's official cross-reference database — do not assume compatibility from package match alone."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2155TDBTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR2155TDBTR when reusing this data.
