50 MHz Cortex-M3 with CAN and serial flexibility
The Texas Instruments LM3S2608-IQC50-A2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 2000 series, clocked at 50 MHz with 128 KB of Flash and 32 KB of RAM.
This is a phase-out posture from Texas Instruments — the part remains available for existing production runs through surplus and independent channels, but no new design should start with this order code.
Key ratings for the design decision
The 50 MHz core speed sets the timing budget for interrupt latency and peripheral throughput — adequate for a single CAN node and a UART logging stream without bus contention. The 32 KB RAM is the tighter resource; a full CANopen or Modbus stack plus a modest data buffer fits, but heavy graphics or multi-protocol gateway applications will bump against the ceiling.
