It carries a full set of peripherals including CAN, USB OTG, multiple serial interfaces, and a 16-channel 10-bit ADC — enough to handle a mixed-signal control board without external ADCs. ## Peripheral set and package 67 I/O lines are brought out to a 100-LQFP package with a 14x14 mm body — the 0.5 mm pitch demands a 4-layer PCB for reliable fan-out. On-chip oscillator eliminates the external crystal for most applications, though the USB OTG peripheral still requires a precision clock source. Brown-out detect, POR, and watchdog timer are integrated — no external supervisor IC needed for basic reset handling.","metaTitle":"LM3S5651-IQC80-C5T Texas Instruments MCU, 80MHz, 128KB Flash","metaDescription":"Obsolete Texas Instruments Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB Flash, 32K x 8 RAM, 100-LQFP.","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":"Tape & Reel (TR)","RAM Size":"32K 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":"LM3S5651","Program Memory Size":"128KB (128K 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":"$7.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9315fa200c803917e7b307e71a010347.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5651-IQC80-C5T/alternatives.json"},"ai":{"faq":[{"question":"How do I get pricing and availability for LM3S5651-IQC80-C5T?","answer":"Submit an RFQ through this listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5651-IQC80-C5T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S5651-IQC80-C5T when reusing this data.
