There is no listed successor order code in the available records, so a pin-compatible direct replacement from TI's current Stellaris or Tiva-C portfolio is not confirmed. For production continuity, the only channel is the surplus and broker market. Any lot offered should be verified for date code and authenticity against the original TI marking. ## Sourcing reality for a discontinued controller Because the LM3S8733-IQC50-A2T is obsolete, standard distribution stock is depleted. Buyers should expect to work with date-code-locked inventory and plan for a one-time last-time-buy or a qualified substitute evaluation.","metaTitle":"LM3S8733-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S8733-IQC50-A2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 64 KB SRAM, CAN/Ethernet/I²C/SPI/UART, -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":"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":"35","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","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-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S8733-IQC50-A2T obsolete?","answer":"Yes, the LM3S8733-IQC50-A2T is officially obsolete per the manufacturer's product status."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8733-IQC50-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/LM3S8733-IQC50-A2T when reusing this data.
