The 46 GPIOs, along with the internal oscillator and brown-out/POR/WDT peripherals, reduce external BOM count — you can run a basic node with just the MCU, a magnetics jack, and a 2.5 V supply rail. ## Supply voltage and design-in note That's tighter than the usual 3.3 V MCU, so the regulator selection matters: a 2.5 V LDO with ±2% accuracy keeps you inside the window. The internal oscillator means you can skip an external crystal for non-timing-critical applications, but if you do use one, the oscillator type is internal, so no external resonator is required for basic clocking.","metaTitle":"LM3S6911-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S6911-IQC50-A2 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 50 MHz, 256 KB Flash, 64 KB RAM, Ethernet + serial interfaces.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6911","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$47.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f0d1cd3dce82f535fc087498a0841b14.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6911-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S6911-IQC50-A2 a replacement for LM3S6911-IQC50?","answer":"The base product number is LM3S6911, and the suffix -IQC50-A2 indicates a specific configuration (industrial temp, 50 MHz, 100-LQFP).
