Frequently asked questions
Does the MSP430FR2155TDBTR need a 5V rail or does it run on 3.3V?
Narrow supply window of 1.8V to 3.6V — it needs a regulated rail, typically 3.3V from an LDO or buck converter. 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.
What is the real thermal headroom for this part in an enclosed panel at 85°C ambient?
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.
Is there a second source or drop-in replacement for the MSP430FR2155TDBTR?
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.
