The 64 KB SRAM gives room for packet buffers and state variables without needing external memory. The 256 KB Flash can hold a moderate application plus a bootloader — plan for firmware-over-Ethernet updates within that footprint. ## Ethernet MAC+PHY — no external transceiver needed The integrated Ethernet MAC and PHY saves board space and BOM cost compared to a two-chip solution. The 46 general-purpose I/O pins still leave room for parallel displays, keypads, or additional sensors alongside the network interface. The 108-ball BGA (10x10 mm body) requires a multi-layer PCB with microvias for routing and a controlled reflow profile — not a hand-solder part. No official successor part is recorded on this listing. For production or repair runs, procurement will need to source from independent distribution or the surplus market.","metaTitle":"LM3S6911-IBZ50-A2 ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"LM3S6911-IBZ50-A2 from TI Stellaris series, 32-bit ARM Cortex-M3 MCU at 50 MHz with 256 KB Flash, 64 KB SRAM, Ethernet MAC+PHY, 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":"64K 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":"LM3S6911","Program Memory Size":"256KB (256K 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":"$44.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f0d1cd3dce82f535fc087498a0841b14.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6911-IBZ50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S6911-IBZ50-A2 obsolete?","answer":"Yes, the manufacturer lists LM3S6911-IBZ50-A2 as Obsolete.
