TI ended production on this Stellaris family line, so the only available stock is what remains in independent distribution or surplus channels. For a BOM that already qualifies this MCU, the procurement path is to source from verified independent inventory — we quote against an RFQ with confirmed traceability and date codes. ## 80 MHz Cortex-M3 with Ethernet and USB OTG The 80 MHz ARM Cortex-M3 core runs real-time control loops and TCP/IP offload without an external network coprocessor. The integrated Ethernet MAC and USB OTG controller are the headline differentiators — this part was designed for applications needing both wired networking and USB host/device capability on a single chip. The 60 general-purpose I/O pins, DMA, PWM, and watchdog timer round out the feature set for motor drives, building automation gateways, and industrial HMIs. ## BGA footprint and rework considerations The 0.8 mm ball pitch is manageable with standard stencil apertures, but the supply voltage (1.235 V to 1.365 V core) demands a clean, low-noise rail — a separate LDO or DC-DC is typical.","metaTitle":"LM3S9790-IBZ80-C1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9790-IBZ80-C1 is a 32-bit ARM Cortex-M3 MCU from the Stellaris series, 80 MHz core, 128 KB Flash, 64 KB SRAM, Ethernet & USB OTG, 108-BGA, -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":"64K 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, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9790","Program Memory Size":"128KB (128K 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":"$9.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/57393517221c83ebf3150b260ab088b1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9790-IBZ80-C1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S9790-IBZ80-C1?","answer":"Submit an RFQ for current availability and pricing; we confirm traceability and date codes at quote time."},{"question":"Is LM3S9790-IBZ80-C1 obsolete?","answer":"Yes, the product status is Obsolete.
