The LM3S1J16-IQR50-C1: It carries 128 KB of program Flash and 20 KB of SRAM, which together handle moderate control and communication tasks — think motor control, sensor hubs, or industrial protocol bridging.
An internal oscillator is on board, so a basic design can start up without an external crystal, though the clock tree supports external sources when tighter timing is needed.
On-chip data conversion and system monitoring
An 8-channel 10-bit ADC is integrated, enough for reading analog sensors, potentiometers, or current-sense resistors without an external converter. DMA offloads the core during data transfers, which matters when you are polling multiple serial interfaces or streaming ADC samples.
