If you need to stage an OTA update, the 512 KB Flash gives you room for a dual-bank strategy with a fallback image. ## Peripherals set for motor control and sensor fusion The peripheral list includes PWM, QEI, DMA, watchdog, brown-out reset, and POR. The 16-channel 12-bit ADC can sample current-sense resistors and position sensors simultaneously. ## Lifecycle and supply — active, no end-of-life pressure That means it is safe to qualify for a new design with a multi-year production horizon.","metaTitle":"Texas Instruments LM3S6G65-IQC80-A1T ARM Cortex-M3 MCU","metaDescription":"TI Stellaris LM3S6G65-IQC80-A1T: 32-bit ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64KB RAM, integrated Ethernet MAC+PHY, 100-LQFP, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S6G65-IQC80-A1T","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tape & Reel (TR)","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/7e823aff022cb066c93d9562708c6a00.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LM3S6G65-IQC80-A1T support Ethernet?","answer":"Yes.
