The 43 general-purpose I/O pins and built-in peripherals — including I²C, SPI, UART, PWM, and a 4-channel 10-bit ADC — let it interface directly with sensors, actuators, and serial buses without external glue logic. The supply voltage range of 2.25 V to 2.75 V means a single 2.5 V rail or a tightly regulated 2.5 V LDO powers the core and I/O banks, simplifying the power tree. For BOM lines that still require this part, procurement must go through independent distribution or the open market. We source and quote to order against your quantity — confirm the package (100-LQFP, Tape & Reel) and temperature grade match your assembly profile before committing.","metaTitle":"LM3S1165-EQC50-A2T Texas Instruments ARM Cortex-M3 MCU –","metaDescription":"Texas Instruments LM3S1165-EQC50-A2T, 32-bit ARM Cortex-M3 at 50 MHz, 64 KB Flash, 16 KB SRAM, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S1165-EQC50-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","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~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6d1d816cb3103b2ed87edac7417901c1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S1165-EQC50-A2T?","answer":"No official replacement part is listed for this exact order code.
