No direct pin-compatible replacement or successor order code is provided in the official records. For new designs, a current-generation Cortex-M3 or M4 part from TI's Tiva or other series would be the natural migration path, though pin compatibility is not guaranteed.","metaTitle":"LM3S5747-IQC50-A0 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S5747-IQC50-A0 is an obsolete Stellaris ARM Cortex-M3 MCU from TI. 32-bit core at 50MHz with 128KB Flash, 64KB SRAM, CAN/USB, industrial temp.","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":"Tray","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-A0/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for LM3S5747-IQC50-A0?","answer":"No official pin-compatible replacement is documented.
