This is the official signal from Texas Instruments that the part is in its phase-out trajectory — no longer intended for new product designs, though still available for existing production runs and repairs. For a board-level repair technician, this is the part that keeps a legacy controller board running; for a procurement team, it means the supply window is finite. ## 50 MHz core and peripheral mix The 50 MHz ARM Cortex-M3 core is a proven workhorse — not the fastest in the Stellaris family, but fast enough for most real-time control loops and protocol handling. The CANbus interface, alongside I²C, SPI, and UART, makes this MCU a natural fit for a gateway node that bridges a CAN fieldbus to a local sensor network. The 0.5 mm pitch means a standard reflow profile works, but the fine pitch demands a clean solder-paste stencil. The thermal pad is not exposed on this package, so heat dissipation is through the leads only — keep the ambient airflow in mind if the MCU is running near the 105°C limit with all peripherals active.","metaTitle":"LM3S2965-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S2965-EQC50-A2 32-bit ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB SRAM, CAN, I2C, SPI, UART, -40°C to 105°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"56","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2965","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$38.5271","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce414822a550b8e6d450a674e6735501.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2965-EQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2965-EQC50-A2 obsolete or NRND?","answer":"It is not yet fully obsolete, but Texas Instruments has signaled that it is in its phase-out window.
