Frequently asked questions
What is the closest pin-compatible alternative to the LM3S2739-IBZ50-A2T?
TI has not published a direct pin-compatible successor for the LM3S2739 base number; engineers migrating the design should evaluate the Tiva C (TM4C) family as a functional replacement and plan for a pinout review.
What speed does the LM3S2739-IBZ50-A2T run at?
The listed speed is 50MHz — an ARM Cortex-M3 core with no DSP or FPU extension.
What series does the LM3S2739-IBZ50-A2T belong to?
It is a member of the Stellaris ARM Cortex-M3S 2000 series, TI's pre-Tiva naming convention for this MCU family.
