For production runs still locked to this BOM line, the only channel is independent distribution — we source verified stock from our broker network. Each unit is quoted to order, with date codes and condition confirmed before shipment. ## A/D converter and I/O count Sixteen 10-bit ADC channels are integrated, enough for multi-sensor feedback in a motor-drive or power-monitoring application.","metaTitle":"Texas Instruments LM3S5951-IQC80-C1 ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S5951-IQC80-C1 Stellaris ARM Cortex-M3S MCU: 80MHz, 256KB Flash, 64KB SRAM, 67 I/O, USB OTG, CAN, SPI, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 5000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5951","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)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d4b8f5fe4f034d9306544eb41e7eafcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5951-IQC80-C1/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5951-IQC80-C1 obsolete?","answer":"Yes.
