The core supply range is 1.08 V to 1.32 V, separate from the I/O bank. The internal oscillator is used for timing. The LM3S1W16-IQR50-C0 is obsolete. Expect to work with a broker or surplus channel for last-time-buy or spot quantities. ## Peripherals and data conversion The device includes an 8-channel 10-bit ADC, brown-out detect, POR, a PWM module, a watchdog timer, and a DMA controller. The DMA can move data between the ADC result registers and RAM without CPU intervention, which frees the core for control-law math. The PWM outputs are useful for driving a three-phase inverter or a DC-DC converter stage directly, though you will need external gate drivers for power FETs.","metaTitle":"LM3S1W16-IQR50-C0 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1W16-IQR50-C0 is a 32-bit ARM Cortex-M3 MCU from the Stellaris series, 50 MHz, 32 KB Flash, 8 KB RAM, 33 I/O, -40°C to 85°C.","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 1000","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1W16","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b9d77d74fa09210f5608deba6bd6e816.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1W16-IQR50-C0/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1W16-IQR50-C0 obsolete and what is its replacement?","answer":"Yes, the LM3S1W16-IQR50-C0 is obsolete. TI has not published a direct pin-compatible replacement. For new designs, evaluate TI's current Cortex-M3 or M4 families (e.g., Tiva-C or SimpleLink) — expect a different footprint and peripheral set. For existing BOMs, the part is available through surplus and broker channels."},{"question":"What is the equivalent of LM3S1W16-IQR50-C0?","answer":"No official pin-compatible equivalent is listed. The closest functional match within the same Stellaris family would be a higher-density sibling (e.g., with 64 KB or 128 KB Flash) in the same 64-LQFP package, but verify pin compatibility per the specific order code. For a drop-in replacement, you will need to cross-reference the full datasheet and may require a board spin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S1W16-IQR50-C0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S1W16-IQR50-C0 when reusing this data.
