The 100-LQFP package with a 14x14 mm body is a common footprint for mid-range MCUs — a direct pin-compatible replacement would need to match both the package and the 2.25 V to 2.75 V supply rail. A replacement candidate should carry the same temperature range if the original BOM called for it. On-chip peripherals include brown-out detect, power-on reset, PWM, and a watchdog timer. The connectivity block supports CANbus, I2C, IrDA, Microwire, SPI, SSI, and UART/USART interfaces — a broad set that covers industrial fieldbus bridging, sensor communication, and serial debug links. With 60 general-purpose I/O lines and an internal oscillator, the part can run a modest control application without an external clock source, though the internal oscillator's accuracy may limit timing-critical CAN or UART baud-rate windows.","metaTitle":"LM3S2601-IQC50-A2 Texas Instruments ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S2601-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 32KB RAM, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tray","RAM Size":"32K 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":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2601","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.4115","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2601-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for LM3S2601-IQC50-A2?","answer":"Submit an RFQ through this listing."},{"question":"What is the closest pin-compatible alternative to LM3S2601-IQC50-A2?","answer":"A replacement search should start with other Stellaris Cortex-M3 parts in the 100-LQFP package that share the 2.25 V–2.75 V supply range and the same peripheral set — but a board-level review of the pinout and memory map is required before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2601-IQC50-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/LM3S2601-IQC50-A2 when reusing this data.
