The 0.8 mm ball pitch is standard for BGA routing on a four-layer board, but the narrow 2.25 V–2.75 V supply rail needs a clean local LDO with low dropout and good transient response — the regulator output must stay inside that window under load steps.","metaTitle":"Texas Instruments LM3S1165-IBZ50-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S1165-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 16 KB RAM, 43 I/O, 108-LFBGA, -40°C to 85°C, NRND lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S1165-IBZ50-A2T","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tape & Reel (TR)","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","description":"Texas Instruments Stellaris ARM Cortex-M3S 1000 series MCU, 50MHz, 64KB Flash, 16KB RAM, 43 I/O, I²C/SPI/SSI/UART, 108-LFBGA package, −40°C to 85°C, 2.25V–2.75V supply, NRND.","Connectivity":"I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"43","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1165","Program Memory Size":"64KB (64K 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":"$16.5797","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6d1d816cb3103b2ed87edac7417901c1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1165-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1165-IBZ50-A2T obsolete or NRND?","answer":"It is still available for existing production runs, but no guaranteed long-term supply window exists.
