Frequently asked questions
Where can I buy LM3S5791-IBZ80-C5 and how do I get a price?
This part is sourced to order through independent distribution, quoted against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ with your required quantity and date code preference to get a lead time and per-unit price.
What is the closest pin-compatible alternative to LM3S5791-IBZ80-C5?
No formally published pin-compatible second source or drop-in successor order code appears in this record. TI has shifted the Stellaris ecosystem to Tiva C Series, but the Tiva parts use a different pinout and package map — a direct swap requires board re-layout and firmware porting.
What is the LM3S5791-IBZ80-C5 speed rating?
The LM3S5791-IBZ80-C5 runs at 80MHz on an ARM Cortex-M3 core.
What series does the LM3S5791-IBZ80-C5 belong to?
It is a member of the Stellaris ARM Cortex-M3S 5000 series from Texas Instruments.
