This means TI has flagged it for eventual end-of-life; new production designs should avoid this part. The 64-LQFP package with 33 I/O pins provides enough GPIO for sensor interfacing and control logic in a compact board area.","metaTitle":"LM3S5732-IQR50-A0T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S5732-IQR50-A0T Stellaris ARM Cortex-M3 MCU, 50 MHz core, 128 KB Flash, 64 KB SRAM, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","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":"33","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5732","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.4548","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/233e531284d9677c2b02f5dea1e39094.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5732-IQR50-A0T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5732-IQR50-A0T obsolete?","answer":"It is not recommended for new designs, but existing BOMs can still be supported through surplus and broker channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5732-IQR50-A0T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S5732-IQR50-A0T when reusing this data.
