With 33 general-purpose I/O pins and an 8-channel 10-bit ADC, the device handles mixed-signal control tasks without an external converter. The peripheral set includes DMA, PWM, WDT, and multiple serial interfaces — I²C, SPI, UART/USART, SSI, Microwire, IrDA, and LINbus — covering sensor bridges, motor drivers, and fieldbus adapters in a single package. ## Package, supply, and temperature grade Housed in a 64-LQFP (10x10 mm) surface-mount package, the MCU requires a single supply rail from 1.08 V to 3.6 V. Texas Instruments has marked the LM3S1J16-IQR50-C5 as obsolete. Sourcing is through independent distribution channels — quantities are confirmed at RFQ, and the available stock carries date codes consistent with the end-of-life window.","metaTitle":"Texas Instruments LM3S1J16-IQR50-C5, 50MHz Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S1J16-IQR50-C5 Stellaris Cortex-M3 MCU, 50MHz, 128KB flash, 20KB 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":"20K 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":"LM3S1J16","Program Memory Size":"128KB (128K 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 ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4eb1f2120c019042b840bb15071c7cfd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1J16-IQR50-C5/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S1J16-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/LM3S1J16-IQR50-C5 when reusing this data.
