The 43 general-purpose I/O lines in a 100-LQFP package give board-area efficiency for mixed-signal designs that need a handful of analog inputs (4-channel 10-bit ADC) alongside digital peripherals. This part needs a regulated 2.5 V supply — it cannot run from a 3.3 V bus without a series regulator, nor from a 1.8 V rail without a boost. Factor in a low-dropout regulator (LDO) or a DC-DC converter set to 2.5 V when planning the power tree. The Stellaris family has broad distribution support, and the active status means standard lead times apply through authorized channels.","metaTitle":"Texas Instruments LM3S1165-IQC50-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S1165-IQC50-A2T Stellaris ARM Cortex-M3S 1000 MCU: 32-bit single-core at 50 MHz, 64 KB Flash, 16 KB RAM, 43 I/O, 100-LQFP, -40°C to 85°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S1165-IQC50-A2T","Series":"Stellaris® ARM® Cortex®-M3S 1000","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Packaging":"Tape & Reel (TR)","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":"100-LQFP","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":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.1500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6d1d816cb3103b2ed87edac7417901c1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1165-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between LM3S1165-IQC50-A2T and LM3S1168?","answer":"The LM3S1168 is a higher-density sibling in the same Stellaris Cortex-M3 family."},{"question":"What package does LM3S1165-IQC50-A2T use?","answer":"The LM3S1165-IQC50-A2T is supplied in a 100-pin LQFP package with a 14x14 mm body (supplier device package 100-LQFP).
