The LM3S5651-IBZ80-C3T: Its 80 MHz core runs from 1.08 V to 1.32 V core supply, with 128 KB of program Flash and 32 KB of SRAM — enough for moderate firmware stacks, communications protocol handling, and real-time control loops. The 108-ball BGA package (10x10 mm) keeps the footprint compact, but the fine pitch means the PCB layout needs careful via fanout planning.
The 16-channel 10-bit ADC handles analog sensor inputs without an external converter.
For a production BOM, this part is a single-source risk: you cannot order fresh factory stock. Any new design should migrate to a current-generation Cortex-M3 or Cortex-M4 part, though the BGA footprint and peripheral mix will require a layout change.
Because the LM3S5651-IBZ80-C3T is obsolete, it is sourced exclusively through independent distribution channels. There is no factory lead time to reference — the supply is whatever the broker market holds. If you are filling a repair or sustainment BOM line, we can search inventory; for a new build, plan for a last-time-buy or a form-fit-function replacement.
