The 64 KB SRAM handles packet buffers and moderate data arrays — enough for a Modbus TCP gateway or a BACnet controller, though you'll want to budget the heap if you're running a web server. ## Package and temperature grade — assembly and environment The 108-BGA (10x10 mm) package is a fine-pitch ball grid array — not a hand-solderable part. You'll need a stencil, reflow oven, and X-ray inspection for the BGA joints. That means no last-time-buy scramble and no forced redesign for a replacement. For dual-sourcing resilience, the Stellaris family includes pin-compatible siblings with different memory or peripheral mixes, though the exact Ethernet+PHY combination is specific to this tier.","metaTitle":"TI LM3S6G11-IBZ80-A1T ARM Cortex-M3 MCU, 80MHz, 512KB Flash","metaDescription":"Texas Instruments Stellaris LM3S6G11-IBZ80-A1T ARM Cortex-M3 MCU: 80MHz core, 512KB Flash, 64KB SRAM, integrated Ethernet MAC+PHY.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S6G11-IBZ80-A1T","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6G11","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5484b8003e309b44d5692f23e4aba1a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to LM3S6G11-IBZ80-A1T?","answer":"Within the Stellaris ARM Cortex-M3S 6000 series, pin-compatible siblings offer different Flash/SRAM densities or peripheral sets, but the integrated Ethernet MAC+PHY is specific to this part number.

TI's Stellaris tools (now part of the TivaWare ecosystem) provide drivers, peripheral libraries, and a TCP/IP stack. Any ARM-compatible IDE (Keil, IAR, GCC-based) can target it; the internal oscillator lets you start development without an external clock."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S6G11-IBZ80-A1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S6G11-IBZ80-A1T when reusing this data.
