The 80 MHz Cortex-M3 core handles the protocol processing and control loops in one part, cutting BOM count versus a two-chip MCU-plus- Ethernet-controller approach. The 64K x 8 SRAM supports moderate packet buffering; designs with heavy throughput should budget the DMA engine for memory-to-peripheral transfers. ## 108-BGA (10x10) — rework and layout realities The 108-ball BGA on a 10x10 mm body is a fine-pitch part. Internal oscillator is on-chip, but the Ethernet PHY needs an external crystal or oscillator for the MAC clock. ## Peripherals and I/O count The PWM channels are useful for motor drive or LED dimming; the DMA engine offloads the core during Ethernet frame transfers. The 46 I/O count is adequate for a control board with a parallel LCD, keypad matrix, and sensor inputs, but check the pin-mux table in the datasheet for peripheral conflicts before committing the schematic. For BOM planning, that removes the urgency to qualify a replacement or stockpile. The base product number LM3S6G11 covers the family, and the IBZ80-A1 suffix specifies the 80 MHz speed grade and BGA package variant.","metaTitle":"LM3S6G11-IBZ80-A1 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S6G11-IBZ80-A1 32-bit ARM Cortex-M3 MCU from Stellaris 6000 series. 80MHz core, 512KB Flash, 64K x 8 RAM, Ethernet, 46 I/O, -40~85°C, 108-BGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","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, 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","Data Converters":"-","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":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S6G11-IBZ80-A1","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-A1 when reusing this data.
