For designs that need to run a full Ethernet protocol suite with a small RTOS, this memory partition is the practical floor — you will be managing the heap and stack allocation carefully. The Flash is field-programmable, so firmware updates over Ethernet are possible with a bootloader. The 108-LFBGA package measures 10x10 mm (supplier device package 108-BGA 10x10). The official lifecycle status is Obsolete. New-production units are no longer available from the manufacturer. For a production BOM that requires this exact footprint and peripheral set, securing inventory now is the only path — there is no pin-compatible direct replacement from TI for this specific order code.","metaTitle":"LM3S6911-EBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S6911-EBZ50-A2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris LM3S6000 series. 50 MHz core, 256 KB Flash, 64 KB SRAM, Ethernet MAC+PHY, 46 GPIOs.","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~105°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":"https://cdn.icboms.com/6aba2bee8c3c8ea07bd9653bb2ef10b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6911-EBZ50-A2/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S6911-EBZ50-A2?","answer":"Texas Instruments has not published a direct pin-compatible replacement for the LM3S6911-EBZ50-A2 within the Stellaris family. The Stellaris line has been superseded by the Tiva C Series (TM4C123x / TM4C129x), but those parts differ in package, peripheral set, and supply voltage.
