The 64 KB RAM handles Ethernet frame buffers and multiple protocol contexts — useful for a device that needs to talk on the network while running local control loops. With 46 GPIOs in the 100-LQFP package, most designs won't run out of pins for local I/O. ## Package and layout note The internal oscillator means you can skip the external crystal for non-timing-critical applications, though the Ethernet PHY will still need its own reference clock.","metaTitle":"LM3S6G65-IQC80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S6G65-IQC80-A1 Stellaris ARM Cortex-M3 MCU with 80 MHz core, 512 KB Flash, 64 KB RAM, integrated Ethernet MAC.","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, 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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7e823aff022cb066c93d9562708c6a00.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6G65-IQC80-A1/alternatives.json"},"ai":{"faq":[{"question":"Can LM3S6G65-IQC80-A1 be used for Ethernet applications?","answer":"Yes, the device includes an integrated Ethernet MAC controller in its connectivity block.
