That means no last-time-buy deadline, no forced redesign for a replacement.","metaTitle":"Texas Instruments LM3S1N16-IQR50-C3 ARM Cortex-M3 MCU","metaDescription":"Texas Instruments Stellaris LM3S1N16-IQR50-C3 32-bit ARM Cortex-M3 MCU at 50 MHz with 64 KB Flash, 12 KB SRAM, 33 I/O, 64-LQFP, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","RAM Size":"12K x 8","Core Size":"32-Bit Single-Core","Packaging":"Tray","EEPROM Size":"-","Part Status":"Obsolete","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","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1N16","Program Memory Size":"64KB (64K 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":"$9.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5aed95a42444630078a60d451a0fe8b8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1N16-IQR50-C3/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1N16-IQR50-C3 obsolete?","answer":"No — the lifecycle record lists this part as active."},{"question":"What is the replacement for LM3S1N16-IQR50-C3?","answer":"No official replacement part number is recorded in the lifecycle data.
