Frequently asked questions
Who supplies the LM3S1R21-IBZ80-C3T and how is it quoted?
Sourced through independent distribution as a quoted-to-order line — availability and current pricing confirmed at RFQ time.
What is the speed rating of the LM3S1R21-IBZ80-C3T?
The listed speed is 80MHz on the ARM Cortex-M3 core.
What Stellaris series does the LM3S1R21-IBZ80-C3T belong to?
It is listed under the Stellaris ARM Cortex-M3S 1000 series.
Is the 108-BGA package reworkable by hand?
The 108-lead LFBGA at 0.65mm ball pitch requires pre-bake and bottom-side preheat for reliable rework — the package thermal mass and hidden solder joints demand a deliberate rework process rather than a quick hot-air touch-up.
