For designs that need to log data or run a small RTOS, the available RAM is generous compared to typical 64 KB Cortex-M3 parts in the same package class. ## Obsolete — sourcing reality and what to expect The LM3S9B92-IBZ80-C1T is officially marked as obsolete by Texas Instruments. We source these parts to order against an RFQ, verifying authenticity and condition before shipment. ## 108-ball BGA — layout and rework considerations The 108-LFBGA package (10x10 mm body, 0.8 mm ball pitch) requires a multi-layer PCB with microvias or blind vias to route all 65 I/O plus the Ethernet and USB differential pairs. The supply voltage is a narrow 1.235 V to 1.365 V core rail — a clean 1.3 V LDO or switching regulator with tight tolerance is needed, and the decoupling layout should follow the Stellaris hardware design guide to avoid brown-out resets.","metaTitle":"LM3S9B92-IBZ80-C1T Stellaris Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9B92-IBZ80-C1T is an obsolete Stellaris ARM Cortex-M3 MCU, 80 MHz, 256 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":"Tape & Reel (TR)","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":"108-LFBGA","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":"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/c535d4c2dcba82f1668e87d4925bc3b9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM3S9B92-IBZ80-C1T obsolete?","answer":"Yes, the LM3S9B92-IBZ80-C1T is listed as obsolete by Texas Instruments.
