That memory budget suits a single control loop plus a protocol stack — think a sensor hub polling I²C peripherals and reporting over UART — but a full TCP/IP stack or a large RTOS footprint will push past the flash boundary. The industrial temperature range (-40 to 85 °C) qualifies it for factory-floor and outdoor enclosures. Texas Instruments has marked the LM3S1W16-IQR50-C5 as Obsolete. ## 64-LQFP package and board-fit Housed in a 64-LQFP (10x10 mm) package, the MCU uses a standard 0.50 mm pitch that routes cleanly on a two-layer board for the 33 I/O lines. The 8-channel 10-bit ADC is on-chip, saving an external converter for basic analog sensing.","metaTitle":"Texas Instruments LM3S1W16-IQR50-C5 Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S1W16-IQR50-C5 Stellaris ARM Cortex-M3 MCU, 50 MHz, 32 KB Flash, 8 KB SRAM, 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":"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-C5/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S1W16-IQR50-C5","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-C5 when reusing this data.
