That is a self-contained control core for a sensor-fusion board or a small motor drive — no external supervisor needed. That means Texas Instruments is winding down production; new designs should not start with this part. For existing BOM lines, you are looking at last-time-buy or independent-distribution sourcing. Because this MCU is NRND, standard distributor stock is drying up.","metaTitle":"LM3S1165-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1165-IBZ50-A2: 32-bit ARM Cortex-M3 MCU at 50 MHz, 64 KB Flash, 16 KB RAM, 108-BGA, -40 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 1000","Package":"Tray","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","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","Product Status":"Not For New Designs","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":"$19.3855","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6d1d816cb3103b2ed87edac7417901c1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1165-IBZ50-A2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S1165-IBZ50-A2?","answer":"We source the LM3S1165-IBZ50-A2 through independent distribution.
