An internal oscillator is available, though an external crystal is recommended for Ethernet timing accuracy. The 100-LQFP package has a central thermal pad; for continuous operation near the 85°C limit, a via stitch under the pad helps keep junction temperature in check.","metaTitle":"LM3S6G65-IQC80-A2 Texas Instruments Stellaris ARM Cortex-M3","metaDescription":"Texas Instruments Stellaris LM3S6G65-IQC80-A2 ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64KB RAM, Ethernet MAC, -40°C to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S6G65-IQC80-A2","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, 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":"LM3S6G65","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/5ee6a55232e41a6de42f113d825300e3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LM3S6G65-IQC80-A2 have an Ethernet MAC?","answer":"Yes, it includes an integrated Ethernet MAC (Media Access Controller) as part of its connectivity peripheral set.
