Any stock you find is new-old-stock or surplus pulled from the authorized channel before the last-time-buy window closed. The laser etch and top-marking consistency across a lot are your first check — a mismatched date-code font or sanded surface on a BGA package is a counterfeit flag. We source this part exclusively through independent distribution and authenticate each reel or tray before it ships. ## 50 MHz Cortex-M3 with Ethernet — the peripheral set The Ethernet MAC is the headline peripheral — it puts a full 10/100 MII interface on the die, which was a differentiator for this generation of Stellaris parts. Alongside Ethernet you get I²C, SPI, SSI, Microwire, IrDA, and UART/USART connectivity, plus 46 GPIOs, PWM, a watchdog timer, and brown-out detect/POR. The 108-LFBGA package measures 10x10 mm with a 0.8 mm ball pitch. That pitch is comfortable for a standard BGA rework station — no micro-BGA tricks — but the 10x10 array still needs a good x-ray after reflow to catch head-in-pillow voids. MSL rating is not in the record, so treat it as MSL 3 unless a date-code trace gives you the bake history.","metaTitle":"LM3S6611-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S6611-IBZ50-A2T Texas Instruments Stellaris ARM Cortex-M3 MCU. 50MHz, 128KB Flash, 32KB RAM, Ethernet MAC, 108-BGA.","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":"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-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S6611-IBZ50-A2T obsolete?","answer":"Yes.
