Frequently asked questions
What replaces the LM3S5G51-IQC80-A1T?
Texas Instruments did not publish a direct pin-compatible successor for this specific order code. The Stellaris family overall was migrated to the Tiva C Series; an equivalent Tiva C part in the 100-LQFP package with USB OTG, CAN, and similar memory complement is the migration target for new designs.
Who supplies the LM3S5G51-IQC80-A1T and how is it quoted?
This part is sourced to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — not a live inventory claim. For volume requirements or a BOM-line commitment, submit an RFQ and the sourcing team will confirm lead time and qty availability.
What is the speed rating of the LM3S5G51-IQC80-A1T?
The listed speed is 80MHz, driven by the ARM Cortex-M3 core clock.
What series does the LM3S5G51-IQC80-A1T belong to?
It is a member of the Stellaris ARM Cortex-M3S 5000 series — TI's mid-range 32-bit MCU family before the brand was rebranded as Tiva C.
