The 64 KB SRAM gives room for data buffers (USB packets, CAN message queues, ADC sample arrays) without needing external memory. If your application requires over-the-air updates, the Flash endurance is unspecified here, but typical Stellaris parts support 100k write/erase cycles per sector — budget for wear-leveling if you update frequently. The 16-channel 10-bit ADC is included. The 108-ball LFBGA (10x10 mm) package requires a 1.08 V to 1.32 V core supply. ## Lifecycle reality: obsolete, sourced to order The product status is Obsolete.","metaTitle":"Texas Instruments LM3S5951-IBZ80-C5 ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments Stellaris LM3S5951-IBZ80-C5 ARM Cortex-M3 MCU: 80MHz, 256KB Flash, 64KB SRAM, USB OTG, CAN, LIN, 67 I/O, -40°C to 85°C, 108-LFBGA.","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":"108-LFBGA","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":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d4b8f5fe4f034d9306544eb41e7eafcc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5951-IBZ80-C5/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S5951-IBZ80-C5?","answer":"No official replacement part number is recorded in the available records.
