The 100-LQFP (14x14 mm) package has a fine pitch suitable for rework with a hot-air station. The internal oscillator allows operation without an external crystal for UART baud-rate generation.","metaTitle":"Texas Instruments LM3S6C65-IQC80-A1 ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S6C65-IQC80-A1 Stellaris ARM Cortex-M3 MCU: 80MHz, 512KB Flash, 64KB RAM, Ethernet + I²C/SPI/UART, -40°C–85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S6C65-IQC80-A1","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6C65","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5201edd73f6507996bad42358827830d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6C65-IQC80-A1/alternatives.json"},"ai":{"faq":[{"question":"What is the pin-compatible equivalent or replacement for LM3S6C65-IQC80-A1?","answer":"Within the Stellaris 6000 series, pin-compatible density variants exist — the same 100-LQFP footprint carries different Flash/RAM combinations. The base product number LM3S6C65 identifies this specific 512 KB / 64 KB configuration. For a drop-in alternate with the same pinout, check the LM3S6xxx family in the same package; the exact order code determines the memory size and peripheral set."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S6C65-IQC80-A1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S6C65-IQC80-A1 when reusing this data.
