It integrates an Ethernet MAC controller, four 10-bit ADC channels, and 42 GPIOs, making it suited for industrial control, building automation, and networked embedded systems that require a compact BGA footprint. The LM3S6965-IBZ50-A2T is marked Obsolete by the manufacturer. For new designs, TI's TM4C12x series (Cortex-M4F) is the architectural evolution, but it is not pin-compatible. ## Package and temperature grade — board-level fit 108-ball LFBGA (10×10 mm) package. -40°C to 85°C temperature range. Supply voltage 2.25 V to 2.75 V. Internal oscillator available.","metaTitle":"TI LM3S6965-IBZ50-A2T ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"TI Stellaris LM3S6965-IBZ50-A2T ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, Ethernet MAC, 108-LFBGA, -40°C to 85°C.
