For a hobbyist building a connected robot or a networked sensor node, this one chip handles the Ethernet stack, the motor encoders, and the serial console — no extra interface chips needed. The LM3S9792-IQC80-C0 carries an official lifecycle status of Obsolete. TI ended production on the Stellaris line after acquiring Luminary Micro and transitioning to the Tiva C series. There is no direct pin-compatible replacement from TI — the Tiva TM4C devices use a different pinout and peripheral map. For an existing design that already has the PCB laid out for this 100-LQFP footprint, your options are to buy remaining stock through independent distribution or to plan a board spin. ## Sourcing a legacy Stellaris part The independent market is where you'll find it — new-old-stock from excess inventory, or pulled from unused production runs. When you submit an RFQ, we check our multi-source network for date codes and quantities that match your BOM need. For a production line that can't respin the board, we can also quote a lifetime buy quantity if you have a forecast. The 100-LQFP package is common enough that broker stock tends to be available, but the window narrows every year.","metaTitle":"LM3S9792-IQC80-C0 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S9792-IQC80-C0 Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB Flash, 64KB RAM, Ethernet/USB OTG, -40°C 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, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"65","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":"LM3S9792","Program Memory Size":"128KB (128K 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/7b0ea84b7316f3fefb74bd3a6944c6c4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy LM3S9792-IQC80-C0 and how do I get a price?","answer":"The LM3S9792-IQC80-C0 is obsolete and sourced through independent distribution. Submit an RFQ through this listing; we confirm availability and current pricing at quote time against your required quantity. No stock or price figures are published because the spot market moves daily."},{"question":"What is the replacement for LM3S9792-IQC80-C0?","answer":"There is no direct pin-compatible replacement from Texas Instruments. The Tiva C series (TM4C) devices are the architectural successor but use a different pinout and peripheral mapping. A board redesign is required to migrate. For existing boards, the best option is sourcing the original LM3S9792 from surplus inventory."},{"question":"Is LM3S9792-IQC80-C0 compatible with LM3S9791?","answer":"The LM3S9791 and LM3S9792 share the same Stellaris family and 100-LQFP package, but compatibility depends on the specific peripheral and memory differences between the two base part numbers. Without a verified cross-reference from TI, you should compare the datasheets pin-for-pin before assuming drop-in replacement. The LM3S9792 has 128 KB Flash and Ethernet; the LM3S9791 may differ in memory size or peripheral set."},{"question":"What is LM3S9792-IQC80-C0's listed speed on this component line?","answer":"The LM3S9792-IQC80-C0 is rated for a core speed of 80 MHz, based on the ARM Cortex-M3 processor running from an internal oscillator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9792-IQC80-C0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9792-IQC80-C0 when reusing this data.
