Product details

50 MHz Cortex-M3 with industrial peripheral set

The 100-LQFP package gives you 34 general-purpose I/O lines, plus a 3-channel 10-bit ADC for analog feedback.

If you are supporting a legacy Stellaris-based design, verify your stock position and qualify a pin-compatible replacement for new builds.

Frequently asked questions

What is the closest pin-compatible alternative to LM3S2432-EQC50-A2T?

Within the Stellaris family, the LM3S2xxx series shares the same 100-LQFP footprint and Cortex-M3 core, but pin compatibility varies by peripheral set and memory density. Check the TI Stellaris migration guide for a direct drop-in replacement for your specific firmware and I/O allocation.
