The 64 KB Flash and 12 KB RAM limit firmware to moderate code size — think a single protocol stack plus application logic, not a full RTOS with multiple stacks. If your firmware footprint exceeds this, you'll need to step up to a higher-density Stellaris variant or a different family entirely. Connectivity includes I2C, SPI, UART/USART, LIN, IrDA, and Microwire, which covers most industrial sensor and actuator buses. The 8-channel 10-bit ADC is sufficient for basic analog sensing but not high-resolution measurement. ## Obsolete — sourcing strategy for the LM3S1N16-IQR50-C1 The LM3S1N16-IQR50-C1 is listed as obsolete. For existing BOM lines, the only supply channel is the surplus and independent distribution market. Housed in a 64-pin LQFP with a 10x10 mm body, the LM3S1N16-IQR50-C1 is a surface-mount device.","metaTitle":"LM3S1N16-IQR50-C1 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1N16-IQR50-C1 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 64 KB Flash, 12 KB RAM, industrial temp range.","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/5aed95a42444630078a60d451a0fe8b8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1N16-IQR50-C1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S1N16-IQR50-C1?","answer":"No official replacement order code is listed by Texas Instruments.
