The 16-channel 12-bit ADC samples analog inputs for current sensing or temperature monitoring. ## Industrial temperature and package realities The 108-BGA package and date-code consistency should be verified through physical inspection—the laser etch on the package top is a fingerprint that traces back to the original TI plant.","metaTitle":"LM3S5D51-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S5D51-IBZ80-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 512 KB Flash, 96 KB RAM, industrial temp.","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":"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, 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-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5D51-IBZ80-A2 obsolete and what is its recommended replacement?","answer":"Yes, the LM3S5D51-IBZ80-A2 is listed as Obsolete by Texas Instruments. No official replacement part number is recorded in the lifecycle data. For existing designs, the only sourcing path is through independent distributors holding surplus stock. A pin-compatible alternative within the Stellaris family may exist, but without a documented successor, each BOM line should be evaluated for a redesign using a current-generation Cortex-M4 or M33 MCU from TI's Tiva or MSP432 series."},{"question":"What is the exact footprint and package for LM3S5D51-IBZ80-A2?","answer":"The LM3S5D51-IBZ80-A2 is supplied in a 108-LFBGA package with a 10x10 mm body and 0.8 mm ball pitch. The supplier device package is 108-BGA (10x10). PCB land pattern and stencil aperture follow standard JEDEC design rules for a 108-ball BGA; no custom footprint is required beyond the datasheet's recommended layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5D51-IBZ80-A2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S5D51-IBZ80-A2 when reusing this data.
