The 80 MHz core paired with the DMA controller means the CPU can sustain Ethernet and USB traffic without stalling on interrupt overhead — useful for a small industrial gateway or a motor-drive node that also serves a web interface. The 12-bit ADC with 16 channels covers multi-axis current sensing or temperature monitoring on a single chip. ## 108-ball BGA: footprint, rework, and the industrial temperature grade The 108-LFBGA (10x10 mm body) requires a multi-layer PCB for routing the 65 I/O and connectivity signals. BGA rework needs a hot-air station and stencil. Texas Instruments has designated the LM3S9U96-IBZ80-A2 as Obsolete. There is no LTB window remaining through the factory. Engineers planning a new design should evaluate current-generation Cortex-M4 or M7 parts with equivalent Ethernet + USB OTG + CAN peripherals from TI's Tiva C Series or a comparable vendor. Pin compatibility is not guaranteed — a board respin is expected.","metaTitle":"LM3S9U96-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9U96-IBZ80-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 384 KB Flash, 96 KB RAM, 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, 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":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9U96","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What does the 80 MHz core speed mean for this MCU?","answer":"The 80 MHz ARM Cortex-M3 core, combined with the DMA controller, can handle Ethernet and USB OTG traffic without saturating the CPU.
