For a production BOM already qualified on the LM3S2432, the immediate action is to secure last-time-buy quantities through the independent channel. For a new board, the Stellaris family has been superseded by TI's Tiva C Series and later Cortex-M4F parts — but those are not pin-compatible, so a migration involves a PCB spin. ## Industrial temperature and peripheral set — where it still fits","metaTitle":"LM3S2432-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S2432-IQC50-A2T 32-bit ARM Cortex-M3 MCU at 50MHz with 96KB Flash, 32KB SRAM, CANbus, industrial temp range.","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 2000","Package":"Tape & Reel (TR)","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"34","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 3x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2432","Program Memory Size":"96KB (96K 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":"$16.4876","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38b03106a267df1019dd902dd40d5344.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2432-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2432-IQC50-A2T obsolete or NRND?","answer":"It is not actively promoted for new projects, and a future end-of-life notice is expected.

The Tiva C Series (TM4C123x) offers a Cortex-M4F core with more memory and peripherals, but requires a PCB redesign due to different pinout and supply voltage. For a drop-in functional equivalent within the same package and voltage, the LM3S2xxx series siblings with matching memory and peripheral sets are the closest cross-shoppable options, though all are NRND."},{"question":"What is LM3S2432-IQC50-A2T's listed speed?","answer":"The core runs at 50 MHz. At this clock rate, the Cortex-M3 delivers 1.25 DMIPS/MHz, so about 62.5 DMIPS of integer throughput — adequate for real-time control loops and moderate protocol processing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2432-IQC50-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S2432-IQC50-A2T when reusing this data.
