It targets industrial control, motor drive, and connectivity-centric applications where a balanced mix of processing throughput, peripheral integration, and industrial temperature tolerance is needed. The 80 MHz core handles control loops and protocol stacks with headroom; the 512 KB Flash accommodates moderate firmware images without external memory. Supply range is 3V to 3.6V, and the part is rated for -40°C to 85°C, suiting factory-floor and outdoor telecom enclosures. This MCU packs CAN, LIN, USB OTG, SPI, SSI, UART, I²C, IrDA, Microwire, and QEI – a broad connectivity set for multi-protocol gateways, motor-feedback loops, and human-machine interfaces. The 16-channel 12-bit ADC captures analog sensor inputs without an external converter. DMA, PWM, and WDT offload the core for deterministic timing tasks. ## 108-BGA package – board integration note Housed in a 108-LFBGA (10x10 mm body), this BGA requires controlled solder-paste deposition and X-ray inspection. The 67 I/O are routed to the outer balls; inner balls carry supply and ground.","metaTitle":"Texas Instruments LM3S5D51-IBZ80-A1T ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash","metaDescription":"Obsolete TI Stellaris LM3S5D51-IBZ80-A1T 32-bit ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 96 KB SRAM, 67 I/O, 108-BGA, -40 to 85°C.
