For new designs or volume production, a direct pin-compatible replacement within the Stellaris family is not documented in the available cross-reference data. Sourcing is limited to independent-distribution surplus and broker inventory. The core operates from a 1.08 V to 1.32 V supply. ## Industrial temperature grade and 108-BGA footprint The 108-LFBGA package (10x10 mm body) demands a BGA-capable assembly line and X-ray inspection for solder-joint verification. The 67 general-purpose I/O pins provide enough headroom for parallel buses and sensor interfaces.","metaTitle":"LM3S5651-IBZ80-C1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Texas Instruments LM3S5651-IBZ80-C1 32-bit ARM Cortex-M3 MCU, 80 MHz core, 128 KB Flash, 32K x 8 RAM, 108-BGA, -40°C 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":"32K 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":"LM3S5651","Program Memory Size":"128KB (128K 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/9315fa200c803917e7b307e71a010347.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5651-IBZ80-C1/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5651-IBZ80-C1 obsolete?","answer":"Yes, the LM3S5651-IBZ80-C1 is obsolete.
