This part carries a Not Recommended for New Designs (NRND) lifecycle status. That means TI has stopped promoting it for new project starts, though it remains available for existing production runs through the independent distribution channel. ## CAN bus and industrial connectivity on a single chip The 60 general-purpose I/O pins, all in a 100-LQFP package, give enough headroom for parallel LCD interfaces or banked sensor inputs without needing an external GPIO expander.","metaTitle":"LM3S2950-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S2950-IQC50-A2T Stellaris ARM Cortex-M3 MCU: 50 MHz, 256 KB Flash, 64 KB SRAM, CAN bus, -40°C to 85°C.","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":"Tape & Reel (TR)","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":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2950","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.9962","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/58cbdf37a25073ea16048f6f3e02b171.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2950-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2950-IQC50-A2T obsolete?","answer":"It is not fully obsolete, but it is classified as Not Recommended for New Designs (NRND). TI no longer promotes it for new projects, but it can still be sourced through independent distribution for sustaining production. For new designs, a current-production Cortex-M3 or M4 alternative should be evaluated."},{"question":"Does LM3S2950-IQC50-A2T have CAN bus?","answer":"This makes it suitable for CAN-based industrial control networks."},{"question":"What is the replacement for LM3S2950 IQC50 A2T?","answer":"For a pin-compatible replacement within the Stellaris family, check the current TI Cortex-M3 portfolio in the same 100-LQFP footprint — parametric similarity in Flash size, SRAM, and peripheral set is the starting point.
