TI lists the LM3S5747-IQC50-A0T as obsolete. The Stellaris family was migrated to the Tiva C series, but pin compatibility varies by package and peripheral mix — verify against your specific board layout before assuming a swap. If you are qualifying a second source, a parametric search of the Tiva C TM4C123 or TM4C129 series may yield a functional equivalent, though the footprint and supply voltage differ.","metaTitle":"LM3S5747-IQC50-A0T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S5747-IQC50-A0T is a 32-bit ARM Cortex-M3 MCU from the Stellaris series. 50 MHz core, 128 KB Flash, 64 KB SRAM, CAN/USB/I²C/SPI.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 5000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"61","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5747","Program Memory Size":"128KB (128K 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":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5747-IQC50-A0T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5747-IQC50-A0T obsolete and what is its replacement?","answer":"Yes, TI lists this part as obsolete.
