It carries 256 KB of Flash and 64 KB of RAM, enough for a moderate control stack with Ethernet and CAN protocol handling. The peripheral set includes CANbus, Ethernet MAC+PHY, I²C, SPI, SSI, UART, and IrDA — a broad interface palette for industrial gateways, motor drives, or building automation controllers. The 100-pin LQFP package gives you 46 GPIOs, and the operating range covers -40°C to 105°C, so it fits into an enclosure with limited airflow or near a warm power stage. ## Obsolete — sourcing reality for this BOM line The 100-LQFP (14x14 mm) is a standard fine-pitch surface-mount package. It is not a BGA, so visual inspection and rework are straightforward. If your board sees condensation or high humidity, a conformal coat is advisable; the package itself is not hermetically sealed.","metaTitle":"LM3S8970-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 100-LQFP","metaDescription":"LM3S8970-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB RAM, CAN/Ethernet, -40 to 105°C.
