This combination targets industrial control, motor drive, automotive gateway, and sensor hub applications where deterministic real-time response and multiple serial buses are required. No last-time-buy window remains. For existing BOM lines, procurement must source through independent distribution or surplus channels. The 33 I/O lines, combined with CAN, USB, and multiple serial interfaces, allow a single chip to handle both real-time control loops and higher-level protocol stacks without an external bridge.","metaTitle":"LM3S5C36-IQR80-A1 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S5C36-IQR80-A1 Stellaris ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64Kx8 SRAM, industrial temp -40°C to 85°C, 64-LQFP.","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":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5C36","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5C36-IQR80-A1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S5C36-IQR80-A1?","answer":"Texas Instruments has not published an official replacement for this exact order code.
