The internal oscillator reduces external BOM count, though the core supply requires a regulated 1.235 V to 1.365 V rail, separate from the I/O voltage. For production or repair requirements, procurement must rely on surplus inventory or broker channels. The 1.235 V to 1.365 V core supply demands a clean low-noise rail; a local LDO or switching regulator with low ripple is recommended.","metaTitle":"LM3S9997-IQC80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9997-IQC80-C5 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 9000 series. 80 MHz core, 256 KB Flash, 64 KB SRAM, Ethernet/CAN/USB OTG.","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":"$8.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a16760f1b1ed2b544492e5acf48839b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9997-IQC80-C5/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S9997-IQC80-C5 obsolete and what is its recommended replacement?","answer":"Yes, the LM3S9997-IQC80-C5 is marked obsolete. The lifecycle record does not list an official replacement part number. For new designs, consider a current-generation Cortex-M4 or M7 MCU with similar peripheral integration (Ethernet, CAN, USB OTG) from the same or alternate vendor."},{"question":"Where can I buy LM3S9997-IQC80-C5?","answer":"Submit an RFQ for current availability and pricing; quotes are confirmed at order time. Stock positions change frequently for obsolete components, so a direct inquiry is the fastest path to a commitment."},{"question":"What is the core speed and memory configuration of LM3S9997-IQC80-C5?","answer":"The ARM Cortex-M3 core runs at 80 MHz. Program memory is 256 KB of Flash, and data memory is 64 KB of SRAM. This combination supports moderate-complexity firmware with a real-time OS and communication stacks without external memory."},{"question":"What connectivity interfaces does this MCU include?","answer":"The LM3S9997-IQC80-C5 integrates Ethernet MAC+PHY, CAN 2.0B, USB OTG, plus I²C, SPI, SSI, UART, IrDA, LIN, Microwire, and QEI. This makes it suitable for industrial gateways, motor drives, and networked control systems that need both fieldbus and higher-level networking."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9997-IQC80-C5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9997-IQC80-C5 when reusing this data.
