Expert opinion by Maker Marisol · Hobbyist / Maker & Open-Hardware Tinkerer
The Texas Instruments LM3S601-EQN50-C2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 600 series, built for real-time control in industrial and embedded systems. It runs at 50 MHz, with 32 KB of Flash program memory and 8 KB of RAM.
Yes, the LM3S601-EQN50-C2 is obsolete. It is no longer in production and has no active last-time-buy window. For replacement, consider the LM3S600 series within the same Stellaris family — pin-compatible and available through standard distribution.
The LM3S600 series from the same Stellaris family is a pin-compatible replacement. It shares the same 48-LQFP footprint and peripheral set, with higher Flash and RAM options. Check the specific LM3S600 variant for exact memory and speed.
Yes, the LM3S601 and LM3S600 are pin-compatible within the same Stellaris 600 series. They share the same 48-LQFP package and peripheral set, making the LM3S600 a direct drop-in replacement for existing designs.
