The 44 GPIOs are brought out to a 108-ball BGA package measuring 10x10 mm, rated for industrial temperature operation from -40°C to 85°C. ## 50 MHz — what it buys in a control application The 50 MHz core delivers enough throughput for real-time control loops, protocol bridging (UART/SPI/I²C), and basic sensor fusion. If your application requires more memory or higher clock speed, the Stellaris family includes higher-density and faster variants, but none are a drop-in replacement — the BGA footprint and pinout are specific to this die.","metaTitle":"LM3S1133-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S1133-IBZ50-A2 ARM Cortex-M3 MCU, 50 MHz, 64KB Flash, 16KB RAM, 108-BGA.
