The peripheral set suits sensor aggregation, motor-control feedback loops, and serial-communication bridging in industrial and embedded control applications. ## 50 MHz core speed and memory sizing for the BOM The Cortex-M3 core runs at 50 MHz. The 28 I/O lines in a 48-VFQFN Exposed Pad package give decent pin density for the footprint. The exposed thermal pad on the 48-VQFN (7x7 mm) helps pull heat out of the package when the MCU is running continuous ADC conversions and PWM outputs at speed. ## Peripheral set and simultaneous interface use The part supports I²C and SPI simultaneously — these are separate peripheral modules on the Stellaris architecture, not a shared multiplexed block. The part also includes SSI (synchronous serial interface) and Microwire, plus UART/USART for asynchronous serial. ## Lifecycle status and production planning","metaTitle":"Texas Instruments LM3S628-IGZ50-C2 ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S628-IGZ50-C2 Stellaris ARM Cortex-M3 MCU, 32KB Flash, 8KB SRAM, 50MHz, -40 to 85°C, 48-QFN.
