TI no longer manufactures it, so new-production designs should not target this order code. For existing BOM lines, the supply channel is limited to surplus and broker inventory. There is no official TI successor listed for this exact variant, so if you need a drop-in replacement, you will need to evaluate pin-compatible Stellaris siblings or migrate to a newer TI MCU family. ## 108-BGA footprint — layout and rework notes The 108-BGA package measures 10x10 mm with a 0.8 mm ball pitch. That is a hand-solderable ball pitch if you have a decent rework station and stencil, but it is tight enough that a misaligned reflow will short adjacent balls.","metaTitle":"LM3S5D51-IBZ80-A2T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S5D51-IBZ80-A2T Stellaris ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 96 KB RAM, 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 5000","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, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"67","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":"LM3S5D51","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1b9a7c290cdcfa050d2e8b2a487b6b80.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5D51-IBZ80-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5D51-IBZ80-A2T obsolete?","answer":"Yes, this part is listed as Obsolete.
