96 KB of Flash (96K x 8) and 32 KB of RAM (32K x 8) place this MCU in the mid-range of the Stellaris 1000 series. Enough for a single Modbus RTU stack with a few hundred tags, or a sensor-fusion algorithm with moderate data buffers. Not sized for a full TCP/IP stack with large packet buffers — that would push into the higher-density siblings.
The core runs at 50 MHz.
