Texas Instruments no longer accepts orders; available stock is through independent distribution channels. ## 50 MHz Cortex-M3 — what the speed rating delivers The 50 MHz core clock handles a TCP/IP stack for Ethernet communication and a CANopen stack for fieldbus, with cycles left for a PID control loop. The 96 KB Flash is the firmware ceiling; the 64 KB SRAM handles packet buffers and moderate data logging.","metaTitle":"LM3S8530-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S8530-IQC50-A2 32-bit ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, 64 KB SRAM, Ethernet + CAN, -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":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 8000","Package":"Tray","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":"35","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8530","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":"$36.0093","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/594c0611400d8881acfdcb3044ab7677.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8530-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S8530-IQC50-A2 obsolete?","answer":"Yes, the LM3S8530-IQC50-A2 is officially obsolete. The only available supply is through independent distributors sourcing verified surplus and new-old-stock inventory. Every unit we quote is inspected for marking and date-code consistency before shipment."},{"question":"What is a direct replacement for LM3S8530-IQC50-A2?","answer":"The official manufacturer successor for this part is not listed in the available records. For a pin-compatible drop-in, the closest candidates are other Stellaris LM3S8000-series MCUs with the same 100-LQFP footprint, but each variant differs in Flash size, SRAM, and peripheral set. A parametric search against the 50 MHz core, Ethernet + CAN, and 100-pin package is the best approach to identify a functional replacement. We can assist with cross-referencing against available stock on a quote request."},{"question":"Where can I purchase the LM3S8530-IQC50-A2?","answer":"We can quote it against an RFQ with confirmed availability and current pricing at the time of your request. Because the supply is limited to verified surplus and new-old-stock, availability varies — a quick quote request is the most reliable way to check current inventory and lead time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8530-IQC50-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/LM3S8530-IQC50-A2 when reusing this data.
