For BOM lines that still call out this exact code, supply runs through independent distribution and surplus inventory. ## Memory and peripheral budget for the firmware architect The 67 I/O lines in a 108-ball BGA leave about 41 balls for power and ground, which means the layout engineer needs to fan out the inner rows carefully. ## Connectivity set — USB OTG and CAN for industrial links The peripheral list includes USB OTG, CAN, dual SPI, dual UART, I²C, IrDA, LIN, and Microwire. The 16-channel 12-bit ADC covers analog sensing.","metaTitle":"Texas Instruments LM3S5C51-IBZ80-A1 Stellaris ARM Cortex-M3","metaDescription":"Texas Instruments LM3S5C51-IBZ80-A1 Stellaris ARM Cortex-M3S 5000 series MCU, 32-bit single-core at 80 MHz, 512 KB Flash, 64 KB SRAM, 67 I/O, USB OTG, CAN","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 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5C51","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (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/LM3S5C51-IBZ80-A1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S5C51-IBZ80-A1 available via RFQ confirmation?","answer":"Submit an RFQ for current availability and pricing — stock is confirmed at quote time, not listed on the page."},{"question":"What are the key differences between LM3S5C51-IBZ80-A1 and newer Stellaris MCUs?","answer":"Newer Stellaris (now TM4C series) parts typically offer higher core speeds (120 MHz vs 80 MHz), larger Flash and SRAM options, and more advanced peripherals like USB HS and additional CAN channels, but are not pin-compatible with the 108-LFBGA footprint.
