Typical applications include industrial control gateways, building automation controllers, and networked sensor hubs where the combination of wired connectivity and real-time control is required. The 80 MHz core clock places this MCU in the mid-range of Cortex-M3 performance. At this speed, the part can handle real-time control loops, protocol stacks (Ethernet, CAN, USB), and moderate data processing without external memory. The 384 KB Flash is sufficient for a full TCP/IP stack plus application code; the 96 KB SRAM provides headroom for packet buffers and DMA transfers. Designers should budget for the 1.235 V to 1.365 V core supply — a dedicated LDO or switcher is required, as the core rail is not compatible with a standard 3.3 V or 1.8 V supply. ## Connectivity and I/O — what the peripheral set enables With Ethernet MAC, USB OTG, CANbus, and a full suite of serial interfaces (UART, SPI, I²C, LIN, IrDA, Microwire, SSI, QEI), this MCU can serve as the central communication node in a distributed control system. The 65 general-purpose I/O pins, combined with the external bus interface (EBI/EMI), allow connection to parallel LCDs, external SRAM/Flash, or FPGAs. The 16-channel 12-bit ADC covers analog sensor acquisition without an external converter.","metaTitle":"TI LM3S9U92-IBZ80-A1 ARM Cortex-M3 MCU, 80 MHz, 384 KB Flash","metaDescription":"Texas Instruments Stellaris LM3S9U92-IBZ80-A1 ARM Cortex-M3 MCU, 80 MHz, 384 KB Flash, 96 KB SRAM, 65 I/O, -40°C to 85°C, 108-BGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S9U92-IBZ80-A1","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tray","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","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":"108-LFBGA","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":"108-BGA (10x10)","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/fc0303f2fd91b149d5b22f262664ec01.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S9U92-IBZ80-A1?","answer":"For a pin-compatible drop-in, the closest candidates are other Stellaris 9000-series parts in the same 108-BGA package, but no specific successor is documented.
