No last-time-buy dates or successor order code appear in the official record. Any new design-in should target a current-production Cortex-M3 or M4 with Ethernet — the Stellaris family has been superseded by TI's Tiva C Series, though the BGA footprint and peripheral set differ. ## Ethernet on a 108-ball BGA — integration note The Ethernet controller is a key differentiator for this part — it saves an external MAC chip on a board that needs a factory-network or building-automation link. The 50 MHz core has enough headroom to run a lightweight TCP/IP stack alongside the control loop, but the 32 KB RAM limits buffer depth, so plan for a small-footprint stack (uIP or lwIP in reduced mode). The BGA package means all signals route on inner layers; verify that the Ethernet PHY interface (MII/RMII) pins are accessible without excessive via stubs that could degrade signal integrity at 50 MHz.","metaTitle":"LM3S6611-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S6611-IBZ50-A2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 6000 series with 50 MHz core, 128 KB Flash, 32 KB RAM, Ethernet, and industrial temp range.","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":"Tray","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":"108-LFBGA","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~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6611-IBZ50-A2/alternatives.json"},"ai":{"faq":[{"question":"Does LM3S6611-IBZ50-A2 have an Ethernet controller?","answer":"Yes, the connectivity block includes an Ethernet MAC, plus I²C, SPI, SSI, IrDA, and UART/USART interfaces.
