For BOM lines that still call out this exact MPN — legacy production, field-service spares, or a design that cannot migrate — supply runs through independent distribution. Brown-out detect and POR are integrated, which saves an external supervisor on the reset line. ## Package and footprint — 100-LQFP","metaTitle":"LM3S2601-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S2601-EQC50-A2T Stellaris ARM Cortex-M3 MCU: 50 MHz core, 128 KB Flash, 32K x 8 RAM, -40 to 105°C, 100-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 2000","Package":"Tape & Reel (TR)","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2601","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2601-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2601-EQC50-A2T obsolete?","answer":"No official replacement part number has been issued.
