The brown-out detect and watchdog timer are useful for unattended equipment that needs to recover from a glitch without a technician visit. The 32 KB RAM is enough for a modest data buffer or a small RTOS heap, but if your application logs large traces you will want to budget external SRAM or use the SPI to stream to a serial Flash.","metaTitle":"LM3S2620-EQC25-A2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S2620-EQC25-A2 Stellaris ARM Cortex-M3 MCU, 25 MHz, 128 KB Flash, 32 KB RAM, industrial temp -40°C to 105°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":"25MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tray","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, 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":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2620","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":"$22.3039","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e006acc92ec90d976c7b2d9900426dc5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2620-EQC25-A2/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S2620-EQC25-A2 obsolete or still available?","answer":"It is not yet discontinued, so it remains available through distribution for existing production runs, but it is not recommended for new designs."},{"question":"What is the replacement for the LM3S2620-EQC25-A2?","answer":"For new designs, check the current TI Cortex-M3 portfolio for a pin-compatible upgrade with a higher clock speed or more memory."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2620-EQC25-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/LM3S2620-EQC25-A2 when reusing this data.
