The DMA engine offloads data movement from the core, preserving throughput for protocol stacks. The LM3S9997-IQC80-C3 has an Obsolete lifecycle status. No minimum commitment is required for a single BOM line, but the supply is finite — once the surplus inventory is consumed, no further production exists. If you are evaluating a new design, do not qualify this part. The 100-LQFP footprint and the 1.235 V to 1.365 V core supply rail are specific enough that a drop-in replacement does not exist in the current TI portfolio. ## Package and temperature — board-fit checklist The core supply requires a regulated 1.235 V to 1.365 V rail.","metaTitle":"LM3S9997-IQC80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S9997-IQC80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz core, 256KB Flash, 64KB RAM, CAN/Ethernet/USB OTG, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9997","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a16760f1b1ed2b544492e5acf48839b9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy LM3S9997-IQC80-C3?","answer":"We confirm availability and current pricing at quote time — submit an RFQ for the quantity you need, and we will source it from our multi-supplier network."},{"question":"Is LM3S9997-IQC80-C3 obsolete?","answer":"Yes, the LM3S9997-IQC80-C3 carries an Obsolete lifecycle status.
