The 96 KB program memory is sized for a real-time operating system kernel plus a TCP/IP stack and application logic, leaving room for field-upgradeable firmware. The 32K x 8 SRAM supports moderate data buffering — enough for a few Ethernet frames or a command queue — but designs with large lookup tables or extensive logging will need external memory or careful allocation. For BOM sustainment, procurement must turn to the independent distribution channel — surplus inventory, broker-sourced stock, or last-time-buy remnants.","metaTitle":"LM3S6420-IQC25-A2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S6420-IQC25-A2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 6000 series, 25 MHz, 96 KB Flash, 32K x 8 RAM, Ethernet and multiple serial interfaces.","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":"Tray","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":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6420","Program Memory Size":"96KB (96K 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":"$14.6200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6420-IQC25-A2/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S6420-IQC25-A2?","answer":"For a form-fit-function substitute, review the Stellaris family's later Cortex-M3 devices with Ethernet — pin compatibility and peripheral mapping must be verified against the target board's schematic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S6420-IQC25-A2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S6420-IQC25-A2 when reusing this data.
