That is enough for a sensor-fusion loop running at 10 kHz with headroom for the protocol stack (CANopen or Modbus RTU). The single-cycle multiply and hardware divide help keep interrupt latency predictable — important when the PWM or QEI peripheral is driving a motor phase. The 128 KB Flash (128K x 8) and 24 KB SRAM (24K x 8) set the firmware and data-buffer ceiling. A typical CANopen node with a bootloader, a few hundred lines of application code, and a modest data table fits comfortably. If your application requires a full USB host stack, a large lookup table, or over-the-air update staging, you will need to check the image size against this budget before committing the BOM line. TI has ended production; there is no active last-time-buy window. New supply is available only through independent distribution and surplus channels.","metaTitle":"Texas Instruments LM3S5K36-IQR80-C5 ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S5K36-IQR80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash, 24 KB RAM, CAN/USB/LIN, 64-LQFP, -40 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":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 5000","Package":"Tray","RAM Size":"24K 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 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5K36","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/11671dd68ff1b9c954a7f6e13bd75fba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5K36-IQR80-C5/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5K36-IQR80-C5 end of life (EOL)?","answer":"Yes.
