This part is designed for industrial control, sensor aggregation, and motor-drive applications where a moderate-speed Cortex-M3 core and a rich peripheral set are needed in a compact 108-ball BGA package. ## 50 MHz Cortex-M3 — what it buys you At 50 MHz, this core handles UART/SPI/I²C bridging, PWM generation for a two-phase motor, and a modest control loop without breaking a sweat. The 64K x 8 SRAM gives enough headroom for a moderate stack and a few frame buffers — fine for a sensor hub, tight for a GUI.","metaTitle":"LM3S1751-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 108-BGA","metaDescription":"Texas Instruments LM3S1751-IBZ50-A2T 32-bit ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 64K x 8 RAM, -40°C to 85°C, NRND.
