No last-time-buy window remains open through the factory channel, so new-production builds must either source from the independent surplus market or migrate to a replacement. The Stellaris family was TI's Cortex-M3 line that later folded into the Tiva C Series; a functional migration path exists, but it requires a firmware port and a board respin — there is no drop-in pin-compatible successor from TI.","metaTitle":"LM3S6422-EQC25-A2T Stellaris ARM Cortex-M3 MCU, 25MHz","metaDescription":"Texas Instruments LM3S6422-EQC25-A2T Stellaris ARM Cortex-M3 MCU, 25MHz, 96KB Flash, 32KB RAM, Ethernet MAC, -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":"25MHz","Series":"Stellaris® ARM® Cortex®-M3S 6000","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":"Ethernet, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"34","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 2x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6422","Program Memory Size":"96KB (96K 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":"https://cdn.icboms.com/71be020535c3965ee89df4548d8e62de.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6422-EQC25-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S6422-EQC25-A2T obsolete?","answer":"Yes, Texas Instruments has classified this MCU as obsolete.
