The 65 general-purpose I/O lines are multiplexed with the peripheral set; the 16-channel 10-bit ADC provides analog input for sensor conditioning without an external converter. On-chip peripherals include a brown-out detect/reset, POR, DMA controller, I²S audio interface, PWM timers, quadrature encoder interface (QEI), and a watchdog timer — the DMA offloads the Cortex-M3 core during high-throughput Ethernet or USB transfers. An internal oscillator eliminates the external crystal for the core clock, though the Ethernet PHY still requires a 25 MHz reference. For existing BOM lines, this part is sourced through independent distribution channels on a per-RFQ basis.","metaTitle":"Texas Instruments LM3S9B92-IQC80-C1 Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S9B92-IQC80-C1 Stellaris ARM Cortex-M3 MCU, 80MHz, 256KB Flash, 96KB RAM, 100-LQFP.","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 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9B92","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c535d4c2dcba82f1668e87d4925bc3b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9B92-IQC80-C1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S9B92-IQC80-C1 and how do I get a price?","answer":"This part is sourced through independent distribution channels.
