The USB OTG port adds host/device flexibility for data logging or firmware updates via thumb drive. The core supply range is 1.08 V to 1.32 V. That means no further factory orders — no last-time buy window remains open. The only channel is independent distribution: surplus stock, new-old-stock, or broker-sourced units. If your BOM line still calls out this exact code, you are buying from whatever inventory exists in the spot market. No official TI successor is published for this exact order code, so a pin-compatible Stellaris part is the closest cross-ship candidate. ## Package and footprint — 100-LQFP (14×14) The part comes in a 100-pin LQFP with a 14×14 mm body.","metaTitle":"LM3S5651-IQC80-C3T ARM Cortex-M3 MCU, 80MHz, 128KB Flash","metaDescription":"Texas Instruments Stellaris LM3S5651-IQC80-C3T 32-bit ARM Cortex-M3 MCU at 80MHz with 128KB Flash, 32KB RAM, USB OTG, CAN, industrial temp.","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":"32K 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":"LM3S5651","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)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9315fa200c803917e7b307e71a010347.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5651-IQC80-C3T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5651-IQC80-C3T obsolete or end-of-life?","answer":"Yes, Texas Instruments lists the LM3S5651-IQC80-C3T as Obsolete.
