If your design needs more memory headroom, the Stellaris family offers density steps up from this baseline. ## Ethernet and peripheral set — what connects where That covers sensor buses (I²C, SPI), motor-drive comms (LINbus), and debug/console links (UART). The 46 I/O lines are enough to handle a local keypad, LEDs, and a parallel LCD while the serial ports run concurrently. Internal oscillator is available, though an external crystal is typical when Ethernet requires precise clocking. ## Package, supply, and temperature grade The 100-LQFP (14x14 mm body) is a hand-solderable, inspectable package — no BGA rework needed. Supply range is 3.0 V to 3.6 V, compatible with 3.3 V logic families.","metaTitle":"Texas Instruments LM3S6C11-IQC80-A1 Stellaris ARM Cortex-M3","metaDescription":"Texas Instruments LM3S6C11-IQC80-A1 Stellaris ARM Cortex-M3 MCU with 512KB Flash, 64KB SRAM, 80 MHz core, Ethernet, I²C, SPI, UART.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6C11","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4e06553a96706e26149eaf5b023f6598.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LM3S6C11-IQC80-A1 support Ethernet?","answer":"The Ethernet MAC allows direct connection to a PHY for 10/100 Mbit networking."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S6C11-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/LM3S6C11-IQC80-A1 when reusing this data.
