Frequently asked questions
What replaces the LM3S5749-IQC50?
The Stellaris line was absorbed into TI's Tiva C series; a pin-compatible or functionally equivalent alternative in the Tiva TM4C family is the direction to qualify, though the exact order code depends on the flash/RAM sizing and firmware footprint of the target application.
Where can I source the LM3S5749-IQC50 and what are pricing and lead times?
The part is sourced to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time.
What is the speed of the LM3S5749-IQC50?
The LM3S5749-IQC50 runs at 50MHz on an ARM Cortex-M3 core.
