The 64 KB SRAM (organized as 64K x 8) is adequate for moderate data buffers and protocol stacks; designs with large frame buffers or heavy logging may need external memory via the SPI or SSI interface. No official TI replacement has been published for this exact order code. ## Package and mounting — 100-LQFP, tape and reel Surface-mount only.","metaTitle":"Texas Instruments LM3S5951-IQC80-C5T ARM Cortex-M3 MCU","metaDescription":"LM3S5951-IQC80-C5T: 80MHz ARM Cortex-M3, 256KB Flash, 64KB RAM, USB OTG, dual CAN, 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":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 5000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5951","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d4b8f5fe4f034d9306544eb41e7eafcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5951-IQC80-C5T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S5951-IQC80-C5T?","answer":"For new designs, consider a current-production Stellaris or Tiva-C series part with similar peripheral mix — verify pin-compatibility separately, as the LM3S5951 uses a 1.08 V to 1.32 V core supply."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5951-IQC80-C5T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S5951-IQC80-C5T when reusing this data.
