For a production line that depends on the LM3S9L97-IBZ80-C3T, the procurement path is the independent distribution channel — verified surplus or new-old-stock (NOS) inventory. Date-code provenance matters here: any lot surfacing years after the last-time-buy should be inspected for authenticity and moisture-sensitivity compliance.
The 108-LFBGA package measures 10x10 mm. Core supply is 1.235 V to 1.365 V.
We source this obsolete part to order through independent distribution. Submit an RFQ for current availability and pricing; small quantities are typically possible from surplus lots.
