TI has flagged it for eventual phase-out; the existing stock and any last-time-buy window are the only supply path. For a production BOM that already qualifies this MCU, the immediate concern is securing enough units to cover the remaining build horizon. The supply range of 3.0 V to 3.6 V means a single 3.3 V rail powers the core and I/O banks — no separate 1.8 V core supply needed. ## Serial interfaces and peripheral set Connectivity includes I²C, SPI, SSI, Microwire, and UART/USART — enough to talk to external ADCs, temperature sensors, serial Flash, and a host processor without an external bridge. The PWM module and watchdog timer round out the set for motor-drive and safety-critical loops. With 36 I/O in a 48-pin package, about 12 pins are tied to power, ground, and the oscillator — the rest are available for board-level interconnect.","metaTitle":"LM3S800-IQN50-C2 ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"Texas Instruments Stellaris LM3S800-IQN50-C2 32-bit ARM Cortex-M3 MCU at 50 MHz with 64 KB Flash, 8 KB RAM, 36 I/O, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S800-IQN50-C2","Series":"Stellaris® ARM® Cortex®-M3S 800","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S800","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.4520","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cee967c76186fd889b185e4a4b410771.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S800-IQN50-C2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S800-IQN50-C2 obsolete or still available?","answer":"That means TI is not actively promoting it for new projects, but units are still available through the independent distribution channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S800-IQN50-C2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S800-IQN50-C2 when reusing this data.
