The 64 KB SRAM supports packet buffers for Ethernet frames and CAN message queues without external memory. No direct pin-compatible successor is recorded in the lifecycle data. Buyers should verify date-code consistency and marking authenticity — the 100-LQFP package is a common target for re-marked inventory.","metaTitle":"LM3S8930-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S8930-EQC50-A2T from Texas Instruments' Stellaris series: 32-bit ARM Cortex-M3 MCU at 50MHz with 256KB Flash, 64KB SRAM, CAN/Ethernet/I2C/SPI/UART.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 8000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, 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":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8930","Program Memory Size":"256KB (256K 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/c275145768e927033cb6553191b2f837.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8930-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S8930-EQC50-A2T?","answer":"No direct pin-compatible replacement is recorded in the lifecycle data. The Stellaris family has been superseded by TI's Tiva C and later ARM Cortex-M4F series, but those are not drop-in replacements — they differ in pinout, supply voltage, and peripheral map. A BOM redesign is required to migrate."},{"question":"What does the 50 MHz core speed mean for this part?","answer":"The ARM Cortex-M3 core at 50 MHz provides enough throughput for real-time control loops, Ethernet packet processing at 100 Mbps, and CAN message handling without a dedicated communication co-processor. It is not a high-end performance tier — expect around 1.25 DMIPS/MHz — but it is adequate for the industrial gateway and motor-drive applications this part targets."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8930-EQC50-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S8930-EQC50-A2T when reusing this data.
