The device was designed for industrial control, building automation, networking gateways, and motor-drive applications where connectivity and real-time response mattered. ## 80 MHz Cortex-M3 — what the core speed delivers The 80 MHz ARM Cortex-M3 core handles protocol stacks (Ethernet, USB, CAN) plus a control loop. The 96 KB SRAM is sized for packet buffers and data logging alongside the application heap. ## 100-LQFP package — footprint and replacement fit Any pin-compatible replacement candidate must match the 100-LQFP mechanical outline and the 1.235 V to 1.365 V core supply rail. There is no LTB window remaining; procurement relies on existing stock in the broker and surplus market.","metaTitle":"LM3S9U92-IQC80-A1 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S9U92-IQC80-A1 is an obsolete Stellaris ARM Cortex-M3 MCU with 80MHz core, 384KB Flash, 96KB SRAM, Ethernet, USB OTG, CAN.","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":"96K 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 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9U92","Program Memory Size":"384KB (384K 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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fc0303f2fd91b149d5b22f262664ec01.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9U92-IQC80-A1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S9U92-IQC80-A1?","answer":"A pin-compatible functional replacement would need to match the 100-LQFP footprint, 1.235 V–1.365 V core supply, and the Stellaris peripheral set (Ethernet, USB OTG, CAN, 12-bit ADC).
