The 16-channel 10-bit ADC is adequate for reading potentiometers, thermistors, or current-sense resistors in a control loop, but not for precision instrumentation — plan for an external ADC if you need 12+ bits. ## Supply rails and temperature — the bench limits The I/O bank tolerates 3.3 V, but the core regulator must be clean; a noisy rail will produce intermittent crashes that are hell to debug. ## Obsolete — the sourcing reality for a dead line The Stellaris family was migrated to the Tiva C series, but the package and pinout differ — a board spin is required for any direct replacement. Quantities are lot-specific; a full traceability and counterfeit screen is standard before committing to a BOM line.","metaTitle":"TI LM3S9B95-IBZ80-C3T Cortex-M3 MCU, 80MHz, 256KB Flash","metaDescription":"Texas Instruments LM3S9B95-IBZ80-C3T Stellaris ARM Cortex-M3 MCU, 80MHz, 256KB Flash, 96KB RAM, Ethernet+USB+CAN, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S9B95-IBZ80-C3T","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tape & Reel (TR)","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"65","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9B95","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)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e378a3053cb83f2a3c3b90ec0a20194.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9B95-IBZ80-C3T/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S9B95-IBZ80-C3T?","answer":"The Stellaris family was superseded by the Tiva C series, but the package and pinout changed — a direct drop-in replacement does not exist.
