The 128 KB Flash can hold a modest RTOS kernel, the stack, and application code. If you need more memory headroom, the Stellaris family includes pin-compatible parts with larger Flash and RAM, though you will want to check the exact pinout. ## Obsolete — sourcing reality for LM3S6611-EQC50-A2T There is no official TI successor listed for this part; if you need a production-continuity alternative, look at the Stellaris family's later-generation devices or a pin-compatible sibling from the same series — but verify the peripheral set and memory match your firmware image. ## Package and temperature — board-fit details","metaTitle":"LM3S6611-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S6611-EQC50-A2T, Stellaris ARM Cortex-M3S 6000 series 32-bit MCU at 50MHz with 128KB Flash, 32KB RAM, Ethernet & serial interfaces, -40°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tape & Reel (TR)","RAM Size":"32K 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":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6611","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6f0cf319481b5a9465315388f9f931ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6611-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S6611-EQC50-A2T?","answer":"There is no official TI successor listed for this exact order code.
