It can handle real-time control loops, protocol stacks (USB, CAN, TCP/IP offload), and moderate data processing without breaking a sweat. ## Connectivity and peripherals — what is on board A quadrature encoder interface (QEI) is present for motor-feedback applications. The 16-channel 12-bit ADC covers analog sensing needs without an external converter. ## Package and layout — 108-ball BGA Surface-mount assembly requires a standard BGA reflow profile; the package is RoHS-compliant and tape-and-reel for automated pick-and-place. The 67 general-purpose I/Os are distributed around the ball map, so a 4-layer PCB with via-in-pad or dogbone fanout is typical.","metaTitle":"LM3S5C51-IBZ80-A1T Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S5C51-IBZ80-A1T 32-bit ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64KB RAM, USB OTG, CAN, 108-BGA.","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":"64K 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":"LM3S5C51","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":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5C51-IBZ80-A1T/alternatives.json"},"ai":{"faq":[{"question":"Does LM3S5C51-IBZ80-A1T have USB OTG?","answer":"Yes, the LM3S5C51-IBZ80-A1T includes USB OTG (On-The-Go) connectivity, allowing it to operate as either a USB host or device."},{"question":"What is the replacement for LM3S5C51-IBZ80-A1T?","answer":"Texas Instruments has not published an official direct replacement for this specific order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5C51-IBZ80-A1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S5C51-IBZ80-A1T when reusing this data.
