The 50 MHz Cortex-M3 core delivers roughly 1.25 DMIPS/MHz, so you are looking at about 62.5 DMIPS of integer throughput. That is enough for real-time PID loops, basic fieldbus protocol stacks, or a small RTOS tick without breaking a sweat. On the communication side, this MCU brings I²C, SPI, SSI, UART/USART, QEI, and Microwire — a solid mix for talking to sensors, displays, encoders, and serial peripherals. The QEI (quadrature encoder interface) is a nice touch for motor-feedback applications; it decodes position and velocity directly in hardware, offloading the CPU. General-purpose I/O counts 36 pins, which is decent for a 48-pin package. On-chip peripherals include brown-out detect, POR, PWM, and a watchdog timer — the usual safety net for unattended or industrial gear. The internal oscillator saves an external crystal for less timing-critical designs. Supply voltage spans 3V to 3.6V, so a single 3.3V rail does the job. ## Package and board-fit: 48-VQFN with exposed pad Supplied in tray packaging, which is typical for QFN devices in prototype or low-volume production. No reel — so if you are feeding a pick-and-place at scale, budget for a tray-to-reel transfer or order in tube quantities if available. Sourced to order through independent distribution channels. No stock-holding claim — each order is quoted fresh.","metaTitle":"LM3S801-IGZ50-C2 Texas Instruments ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S801-IGZ50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 8 KB SRAM, 36 I/O, -40°C to 85°C, 48-VQFN.
