The official status is not full discontinuation—yet—but the clock is running. ## 50 MHz Cortex-M3 – what the speed rating drives The core runs at 50 MHz, a 32-bit ARM Cortex-M3 single-core processor from the Stellaris® ARM® Cortex®-M3S 1000 series. That clock rate sets the throughput for control loops, protocol processing, and real-time tasks. For a design that needs moderate compute—say a motor control loop with sensor feedback or a protocol bridge—50 MHz is a solid mid-range point. ## Sourcing posture for the LM3S1968-IQC50-A2T For a production line that cannot requalify a new MCU, this is the channel to fill the gap.","metaTitle":"LM3S1968-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1968-IQC50-A2T Stellaris ARM Cortex-M3 MCU with 50 MHz core, 256 KB Flash, 64 KB SRAM, 52 I/O, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1968","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.9835","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/771abe88d51cfa2047951d43f29fd78f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1968-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S1968-IQC50-A2T obsolete?","answer":"It is not fully discontinued, but it is no longer recommended for new designs.
