Frequently asked questions
What is the memory configuration of the LM3S8630-EQC50-A2?
The part carries 128KB of Flash program memory and 32KB of SRAM. This is the key firmware-footprint constraint for your application — any migration target must at minimum match these figures, and the TM4C123 series typically offers 256KB Flash at the same SRAM depth, providing headroom if your firmware supports it.
