If your board already carries a 3.3 V bus, you will need a separate LDO or buck converter to generate this 2.5 V nominal supply. The 50 MHz core speed is achievable across the full voltage range, but the flash requires zero wait states at this clock — no extra latency penalty for the narrow rail. ## 108-ball BGA — assembly and rework considerations The substrate requires a controlled reflow profile per the board-level reliability guidelines. X-ray inspection after assembly is recommended to verify solder-joint integrity.","metaTitle":"Texas Instruments LM3S2651-IBZ50-A2 ARM Cortex-M3 MCU, 50MHz","metaDescription":"TI Stellaris LM3S2651-IBZ50-A2 ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 32KB SRAM, 53 I/O, CAN/SPI/I²C, 2.25V–2.75V, 108-BGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"53","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2651","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)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$31.7923","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2651-IBZ50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is the LM3S2651-IBZ50-A2 compatible with the base LM3S2651?","answer":"The LM3S2651-IBZ50-A2 is a specific ordering variant within the LM3S2651 base family.
