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.","metaTitle":"TI LM3S2608-IQC50-A2T ARM Cortex-M3 MCU, 50 MHz, NRND","metaDescription":"Texas Instruments LM3S2608-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB RAM, 52 I/O, -40 to 85°C.
