On-chip peripherals include a 16-channel 10-bit ADC, PWM outputs, a quadrature encoder interface (QEI) for motor feedback, and a DMA controller that offloads the core during high-throughput transfers. Texas Instruments no longer manufactures this Stellaris-series part, and no official direct replacement has been listed. Supply voltage is a narrow 1.235 V to 1.365 V core rail, so the board needs a dedicated low-noise regulator; the I/O bank runs from a separate 3.3 V supply.","metaTitle":"Texas Instruments LM3S9B92-IQC80-C3 ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S9B92-IQC80-C3 Stellaris ARM Cortex-M3 MCU: 80MHz, 256KB Flash, 96KB RAM, Ethernet, USB OTG, CAN, 100-LQFP, -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":"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/4571a35c0dde868c9065e4a34fd45ca8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9B92-IQC80-C3/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S9B92-IQC80-C3 obsolete?","answer":"Yes, the LM3S9B92-IQC80-C3 is obsolete.
