The 50 MHz ARM Cortex-M3 core delivers around 1.25 DMIPS/MHz, enough for a PID loop at a few kHz, Modbus RTU polling, or a simple HMI with a character LCD. The 64 KB Flash is tight for a full TCP/IP stack — plan for a lightweight protocol like CoAP or a serial-only application. The LM3S1N16 covers the common serial buses: I²C for sensors and EEPROMs, SPI for ADCs or displays, UART for RS-232/RS-485, and LIN for automotive subnets. The IrDA and Microwire interfaces are less common but useful for IR remote control or legacy SPI peripherals. The 8-channel 10-bit ADC at 500 ksps typical is fine for reading potentiometers, thermistors, or current-sense resistors with a simple RC filter.","metaTitle":"LM3S1N16-IQR50-C0 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S1N16-IQR50-C0 Stellaris ARM Cortex-M3 MCU, 50MHz core, 64KB Flash, 12KB RAM, industrial temp -40°C to 85°C, 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":"12K 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":"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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/86788e4cd0934eb95c8ebca26ca40c34.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1N16-IQR50-C0/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S1N16-IQR50-C0 obsolete?","answer":"Yes, the LM3S1N16-IQR50-C0 carries an Obsolete lifecycle status.
