Its 50 MHz core drives 64 KB of program Flash and 12 KB of SRAM, with 33 general-purpose I/O lines and an 8-channel, 10-bit ADC for sensor acquisition. ## 50 MHz and 64 KB Flash — what that means for fit At 50 MHz the Cortex-M3 executes one instruction per cycle on most operations, so the throughput sits around 50 DMIPS — adequate for PID loops, CAN message handling, and Modbus stacks, but thin for heavy DSP or TCP/IP offload. The 64 KB Flash and 12 KB RAM limit firmware to lean real-time kernels (FreeRTOS, TI-RTOS) and protocol buffers; a design needing a full Ethernet stack or large data logging will hit the memory wall. The peripheral set — I²C, SPI, SSI, UART, LIN, and IrDA — covers serial sensor buses and actuator links without external bridge chips. ## Obsolete — sourcing reality for LM3S1N16-IQR50-C0T This part carries an official Obsolete product status. TI has ended production; no last-time-buy window remains open. New-manufacture orders through the factory channel are not possible. The available supply is limited to surplus and broker inventory — material already produced and sitting in distribution. Date-code provenance and traceability become the buyer's primary concern when sourcing an EOL controller for a production run or repair. ## Package and mounting — 64-LQFP footprint The LM3S1N16-IQR50-C0T is supplied in a 64-LQFP package with a 10x10 mm body, surface-mount. The tape-and-reel shipping format suits automated pick-and-place lines.","metaTitle":"LM3S1N16-IQR50-C0T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1N16-IQR50-C0T Stellaris ARM Cortex-M3S 1000 series MCU. 50 MHz core, 64 KB Flash, 12 KB RAM, 33 I/O, 8x10b ADC, -40°C to 85°C.","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":"Tape & Reel (TR)","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-C0T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S1N16-IQR50-C0T?","answer":"The evidence does not list an official TI replacement order code for this specific variant.
