The 96 KB Flash and 64 KB RAM handle moderate application code and data buffers for protocol stacks without external memory. The 100-LQFP (14×14 mm) package keeps the board footprint compact for space-constrained enclosures, and the -40°C to 105°C operating range suits outdoor cabinets, engine compartments, and unheated factory floors where ambient temperatures swing wide. ## CAN and Ethernet: dual-network node in one package The LM3S8530 integrates a CANbus controller and an Ethernet MAC, so a single MCU can bridge a machine's CANopen device network to an upstream Ethernet/IP or Modbus TCP line. The 50 MHz Cortex-M3 has enough headroom to run a lightweight TCP/IP stack alongside the CAN application layer without a second processor. Texas Instruments has marked the LM3S8530-EQC50-A2T as obsolete (EOL). No factory last-time-buy window remains open. New production is not available through authorized distribution. No official pin-compatible second source or TI successor has been published for this exact order code. Any alternate would require a board respin and firmware port. ## Date-code and marking verification Because this part moves through the gray market, the laser etch on the package top is the primary authenticity marker. The TI Stellaris marking follows a defined font and alignment for the 100-LQFP. A decap and X-ray inspection can confirm the die matches the LM3S8530 mask set — the Cortex-M3 core layout and Flash/RAM floorplan are distinctive. Lot date-codes should be consistent across a reel; a mixed date-code lot or a sanded/relabeled surface flags counterfeit risk.","metaTitle":"TI LM3S8530-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"TI Stellaris LM3S8530-EQC50-A2T ARM Cortex-M3 MCU, 50MHz, 96KB Flash, 64KB RAM, CAN & Ethernet, -40°C to 105°C.
