Frequently asked questions
What is the thermal derating situation at 60 °C ambient panel temperature?
The MSP430F67791AIPEUR is rated to -40°C to 85°C TA. At 60 °C ambient you have 25 °C of headroom, which is within standard industrial derating practice for this grade. However, the 25MHz operation and 512KB Flash do not carry an explicit thermal resistance in this dataset — a junction-temperature model is the defensible step before BOM freeze if the board is in a sealed enclosure without forced airflow.
What is the lead pitch and body size of the 128-LQFP?
The MSP430F67791AIPEUR uses a 128-lead LQFP with 0.5mm lead pitch and a 20×14mm body (supplier device package listed as 128-LQFP (20x14)). This matches the standard TI MSP430F6xx 128-pin LQFP land pattern, confirmed drop-fit for existing carrier boards with the same pin count.
How do I verify authenticity before committing surplus stock to a BOM?
For a part at eol_hot lifecycle stage, sourcing through independent traders without TI CofC trace is the primary counterfeit ingress risk on a 512KB Flash device. A CofC from authorised distribution against the TI manufacturing date code is the minimum verification step; full flash-integrity and DMA-channel functional test is the defensible gate before production use of any lot-sourced part.
