This is a part designed for a single-board controller that talks to a CAN bus and manages a handful of analog inputs. ## NRND — plan the last-buy or the swap ## 108-BGA — not a field-swap package This is not a part you swap on site with a soldering iron.","metaTitle":"LM3S2918-IBZ50-A2T Texas Instruments Stellaris ARM","metaDescription":"TI Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB SRAM, CAN/I²C/SPI/UART, 2.25-2.75V, -40 to 85°C, 108-BGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2918","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)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.7092","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7f7688b72c4b8636988af26005ccc872.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2918-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2918-IBZ50-A2T obsolete or NRND?","answer":"It is still available through distribution for existing production, but TI is winding it down. If you need a part for a new design, look at the current Stellaris or TM4C series from TI — they are pin-compatible across many of the same peripheral options."},{"question":"Does LM3S2918-IBZ50-A2T support CAN bus and how many UARTs?","answer":"Yes, it has one CAN 2.0B controller on the connectivity block. The full list of serial interfaces includes CAN, I²C, IrDA, Microwire, SPI, SSI, and UART/USART — so at least one UART is present, and the SSI/SPI pins can be reconfigured for additional UARTs if needed via firmware."},{"question":"What is a reliable replacement or equivalent for LM3S2918-IBZ50-A2T?","answer":"TI does not publish a single direct pin-for-pin replacement for this NRND part, but the TM4C123 series (e.g., TM4C123GH6PM) offers a similar Cortex-M4F core with CAN, more memory, and a wider supply range. The BGA footprint differs, so a PCB respin is required. For a drop-in on an existing board, check the LM3S9B96 or LM3S8962 — they share the Stellaris peripheral set and may have compatible BGA layouts, but verify the ball map against your design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2918-IBZ50-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S2918-IBZ50-A2T when reusing this data.
