The 80 MHz core speed is guaranteed within that window. Program memory is 256 KB of Flash, with 64 KB of SRAM arranged as 64K x 8. That's enough for a USB OTG stack plus a CANopen node and a modest RTOS, but tight if you're adding a GUI library or over-the-air update staging. The 67 GPIOs and the peripheral set — CAN, I²C, SPI, SSI, UART, USB OTG, plus the QEI for motor feedback — make this a natural fit for industrial drives or building automation gateways where the code footprint fits within 256 KB. ## Package and temperature — reflow and environment check The 100-LQFP (14x14 mm body) is a standard JEDEC footprint. No exposed pad, so thermal dissipation goes through the leads.","metaTitle":"LM3S5951-IQC80-C5 Texas Instruments Stellaris ARM Cortex-M3","metaDescription":"Texas Instruments LM3S5951-IQC80-C5 Stellaris ARM Cortex-M3 MCU, 80MHz, 256KB Flash, 64KB RAM, USB OTG, CAN, -40°C to 85°C, 100-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, 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":"LM3S5951","Program Memory Size":"256KB (256K 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":"$7.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d4b8f5fe4f034d9306544eb41e7eafcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5951-IQC80-C5/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S5951-IQC80-C5 obsolete?","answer":"Yes, TI has listed the LM3S5951-IQC80-C5 as obsolete.
