That combination fits applications like a CAN-to-Ethernet gateway or a motor-controller state machine that doesn't need external memory. ## Connectivity peripherals: CAN, Ethernet, and serial interfaces The Ethernet MAC with dedicated DMA is the standout — it enables low-cost embedded web servers or industrial protocol gateways without an external PHY controller. The CAN 2.0B controller suits automotive or factory-floor networking. New-production allocations are gone; any available units are from remaining inventory or the surplus channel. The last-time-buy window has closed, so procurement should verify date-code provenance and plan for a migration if a production run needs ongoing supply. ## Sourcing posture for this obsolete part Buyers should be prepared to evaluate date codes and condition, as this is strictly a surplus-channel part.","metaTitle":"Texas Instruments LM3S8733-IQC50-A2 ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S8733-IQC50-A2 is an obsolete Stellaris ARM Cortex-M3 MCU from TI, 50MHz, 128KB Flash, 64KB RAM, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S8733-IQC50-A2","Series":"Stellaris® ARM® Cortex®-M3S 8000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","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","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8733","Program Memory Size":"128KB (128K 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":"$18.3900","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8733-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S8733-IQC50-A2 obsolete?","answer":"Yes, Texas Instruments lists the LM3S8733-IQC50-A2 as obsolete."},{"question":"What is a good equivalent for LM3S8733-IQC50-A2?","answer":"The Stellaris family has been superseded by the TM4C series from TI, but those parts require a design migration and are not direct substitutes."},{"question":"What is LM3S8733-IQC50-A2's listed speed?","answer":"The core runs at 50 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8733-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/LM3S8733-IQC50-A2 when reusing this data.
