The 2.25V to 2.75V supply rail is tighter than the usual 3.3V single-supply MCU, so the board's regulator must be set for that window. Texas Instruments lists this part as Obsolete. For a BOM that already uses this MCU, the last-time-buy window has closed — any remaining stock is what the market holds. The device brings 46 I/O lines, a 2×10-bit ADC, and a peripheral set that includes I²C, SPI, SSI, UART/USART, IrDA, and Microwire. Brown-out detect, POR, PWM, and a watchdog timer are integrated — enough for a standalone controller without external supervisor ICs. ## 100-LQFP (14×14) — board integration and rework The exposed pad is not present on this package — thermal dissipation relies on the leadframe and board copper. For rework, the fine pitch demands a hot-air nozzle that covers the full body; a standard soldering iron tip won't reach the inner rows.","metaTitle":"TI LM3S1162-IQC50-A2T ARM Cortex-M3 MCU, 50MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S1162-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 16KB RAM, 46 I/O, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S1162-IQC50-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":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 2x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1162","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":"$18.3200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1162-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the core speed and memory configuration of LM3S1162-IQC50-A2T?","answer":"The ARM Cortex-M3 core runs at 50MHz.
