If you're qualifying a new board, you'll want to look at the current Stellaris or TM4C family alternatives; for a repair or a last-production run, this is the exact die you need to match the existing firmware and PCB layout. The 50 MHz core delivers 1.25 DMIPS/MHz, so about 62.5 DMIPS — enough to run a CANopen stack, a Modbus RTU slave, and a PID loop on a motor drive without breaking a sweat. The internal oscillator means you can skip the external crystal for applications that don't need precision timing, saving two pins and a couple of passives. ## Peripherals that matter for industrial and CAN-bus designs The CAN 2.0B controller is the standout here — it's what separates this part from the general-purpose Cortex-M3 parts that only do UART and SPI. The CANbus interface, combined with the 60 I/O and the PWM and WDT peripherals, makes this a natural fit for industrial control nodes, motor drives, and building automation gateways. The brown-out detect and POR keep the firmware from corrupting Flash on a glitchy supply — a real concern on factory floors with big motors cycling on and off. ## Package and temperature grade — fits the industrial panel If your board lives in a conditioned server room, you've got margin; if it sits next to a furnace or a compressor, you're still inside the rated window.","metaTitle":"LM3S2911-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S2911-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB RAM, CAN, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2911","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":"$15.1109","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/24635068039c6dd6f6c46bde82b81374.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2911-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for LM3S2911-IQC50-A2T?","answer":"The Stellaris family has evolved into the TM4C series from Texas Instruments, which shares the Cortex-M3 core and peripheral set.
