It integrates Ethernet and CANbus alongside UART, SPI, SSI, I2C, and QEI, making it a fit for industrial gateways, motor-control nodes, and building-automation controllers that need both wired networking and real-time fieldbus. The 100-LQFP package with 38 GPIOs and an 8-channel 10-bit ADC keeps the BOM compact for mid-complexity embedded designs. Texas Instruments has marked the LM3S8971-EQC50-A2 as Obsolete.","metaTitle":"LM3S8971-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S8971-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64Kx8 RAM, Ethernet & CAN, -40 to 105°C.
