It is not a part for heavy number-crunching or real-time FFT — that would push you toward a higher-clock Cortex-M4 or a dedicated DSP. For its intended role — a connected MCU handling fieldbus bridging and local I/O — 50 MHz is the right fit. Core and I/O share a single regulated rail. Internal oscillator eliminates external crystal in many applications.","metaTitle":"Texas Instruments LM3S8930-IBZ50-A2T Stellaris MCU, 50MHz, EOL","metaDescription":"TI Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, Ethernet + CAN.
