50 MHz Cortex-M3 with 32 KB Flash — what it means for your BOM line
The LM3S600-EQN50-C2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris series, running at 50 MHz with 32 KB of Flash and 8 KB of RAM. It is designed for control-oriented embedded applications.
NRND lifecycle — plan your supply chain accordingly
This part carries an NRND (Not Recommended for New Designs) status and is flagged EOL hot. Production is winding down; no official successor is listed in the evidence.
Industrial temperature grade — deployment context
The -40 to 105°C operating range suits this MCU for environments where the ambient temperature swings beyond commercial limits. Expect it in a motor drive cabinet near the heatsink, an outdoor telecom enclosure with solar gain, or a factory-floor sensor node without active cooling. The 48-LQFP package (7x7 mm) is a standard surface-mount footprint for moderate-density PCBs, routable on two layers with careful decoupling. Internal oscillator means you can skip an external crystal for non-timing-critical UART or I²C buses, saving two I/O pins and a couple of passive components.
