For existing production, the remaining supply moves through independent distribution, and each lot's date-code provenance matters — verify the PCN trail before committing a BOM line. ## 25 MHz Cortex-M3 with Ethernet — peripheral fit and memory headroom The 25 MHz core with 96 KB Flash and 32K x 8 SRAM is sized for control-oriented designs that need a network stack — think remote I/O nodes, industrial gateways, or building-management controllers. The 2x10-bit ADC handles basic analog sensing, and the 34 I/O lines suit moderate GPIO counts. ## 108-ball BGA — layout and rework considerations Housed in a 108-LFBGA (10x10 mm body), this part demands a multi-layer PCB with via-in-pad or microvia capability for fanout. The BGA pitch is fine enough that manual rework needs a hot-air station with a calibrated profile and a reball stencil.","metaTitle":"LM3S6422-IBZ25-A2T Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"Texas Instruments LM3S6422-IBZ25-A2T ARM Cortex-M3 MCU, 25 MHz, 96 KB Flash, 32 KB SRAM, Ethernet, -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":"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":"108-LFBGA","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~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","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/LM3S6422-IBZ25-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S6422-IBZ25-A2T obsolete?","answer":"Yes.
