Connectivity is a strong suit: the MCU integrates CAN, USB OTG, I2C, SPI, SSI, UART, and LIN interfaces, plus a QEI for motor encoder feedback. Texas Instruments has discontinued this Stellaris-series MCU, and no direct factory replacement is listed on the official record. ## 108-ball BGA — rework and layout considerations The 67 I/O are distributed across the ball array, so fanout via microvias or blind vias is typical on a four-layer board. Under a hot-air station, this package is reworkable with practice — the 0.8 mm pitch leaves enough room for a stencil alignment window, and the 10x10 mm body has moderate thermal mass. Pre-bake at 125°C for 24 hours if the moisture barrier bag has been breached, as BGAs are MSL 3 or 3a and can pop during reflow. The orientation mark is a chamfered corner on the package; verify ball A1 location against the datasheet footprint drawing before placing.","metaTitle":"LM3S5C51-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S5C51-IBZ80-A2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 5000 series. 80MHz core, 512KB Flash, 64KB SRAM, 67 I/O, CAN/USB OTG.","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":"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-A2/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5C51-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/LM3S5C51-IBZ80-A2 when reusing this data.
