Frequently asked questions
What is the closest pin-compatible alternate to LM3SA000-IQC50-A2T?
Pin-compatible alternatives within the Stellaris / Tiva-C family should be verified against TI's official cross-reference by your FAE or distributor — no documented second-source or direct successor order code appears in the available record for this specific MPN.
Where can I source LM3SA000-IQC50-A2T and get a quote?
The LM3SA000-IQC50-A2T is sourced to order through independent distribution against an RFQ; availability and current pricing are confirmed at quote time.
What supply voltage does the LM3SA000-IQC50-A2T require?
The device operates on a 2.25 to 2.75 V rail — narrower than a standard 3.3 V nominal MCU supply, so check your power architecture and level-shifting before interfacing to 3.3 V or 5 V peripherals.
