If your application requires over-the-air update staging, budget the Flash footprint: the bootloader plus two image slots typically consume 200-300 KB, leaving 200+ KB for the active application. ## Boot and debug considerations The Cortex-M3 boots from internal Flash with BOOT0 sampled at reset; the JTAG/SWD debug port remains active even with the watchdog enabled, which simplifies firmware bring-up. The 80 MHz PLL requires adjusting Flash wait states before raising the core clock above the default speed — failing to do so causes a hard fault on the first instruction fetch from Flash. The internal oscillator provides a 12 MHz reference for the PLL, but for Ethernet applications requiring precise timing, an external crystal should be considered.","metaTitle":"LM3S6G11-IQC80-A2T Stellaris Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S6G11-IQC80-A2T ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64KB SRAM, Ethernet, -40°C to 85°C, 100-LQFP.","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":"Tape & Reel (TR)","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":"LM3S6G11","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/5484b8003e309b44d5692f23e4aba1a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM3S6G11-IQC80-A2T RoHS compliant?","answer":"The part is listed with a Tape & Reel package suffix (-A2T) typical of RoHS-compliant TI Stellaris devices, but the record does not carry an explicit RoHS certification statement.
