The Texas Instruments Stellaris LM3S1W16-IQR50-C1T is a 32-bit ARM Cortex-M3 single-core microcontroller from the Stellaris® ARM® Cortex®-M3S 1000 series. ## Serial connectivity and peripheral set On-chip peripherals such as DMA, PWM, watchdog timer, brown-out detect, and POR reduce external component count. ## Industrial temperature range and 64-LQFP package ## Supply rail: 1.08 V to 1.32 V core The core supply range is 1.08 V to 1.32 V — a narrow window that demands a regulated rail, not a direct battery tap. A 1.2 V LDO or switching regulator with tight tolerance is expected. The I/O bank voltage is not specified separately in this listing, so confirm the I/O supply compatibility with the rest of the system before committing the BOM.","metaTitle":"Texas Instruments LM3S1W16-IQR50-C1T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments Stellaris LM3S1W16-IQR50-C1T 32-bit ARM Cortex-M3 MCU, 50MHz, 32KB Flash, 8KB RAM, 64-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 1000","Package":"Tape & Reel (TR)","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-C1T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S1W16-IQR50-C1T?","answer":"The LM3S1W16-IQR50-C1T is obsolete and no longer stocked by the manufacturer.
