This means TI will continue to support existing production for a time, but the part is on a path toward end-of-life. For existing designs, secure your last-time-buy quantities or plan a migration. ## Supply range and internal oscillator The Vcc range of 3.0 V to 3.6 V aligns with standard 3.3 V logic. For timing-sensitive protocols like UART at higher baud rates, you may still want an external clock source for tighter accuracy.","metaTitle":"Texas Instruments LM3S800-IQN50-C2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S800-IQN50-C2T Stellaris ARM Cortex-M3S 800 MCU, 32-bit, 50 MHz, 64 KB Flash, 8 KB RAM, 36 I/O, 3V–3.6V, -40°C–85°C, 48-LQFP.","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-C2T","Series":"Stellaris® ARM® Cortex®-M3S 800","Package":"Tape & Reel (TR)","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":"$8.2744","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cee967c76186fd889b185e4a4b410771.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S800-IQN50-C2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S800-IQN50-C2T recommended for new designs?","answer":"No. For new BOMs, select a current-production ARM Cortex-M3 from TI's portfolio or a pin-compatible Stellaris family member."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S800-IQN50-C2T","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-C2T when reusing this data.
