Program memory is 128 KB of on-chip Flash, backed by 64 KB of SRAM — enough headroom for moderate control firmware and a real-time data buffer for sensor fusion or protocol bridging. The core processor is the ARM Cortex-M3, which includes a hardware single-cycle multiply and a Nested Vectored Interrupt Controller for deterministic interrupt latency. Four 10-bit ADC channels are integrated for analog input. Packaged in a 108-LFBGA (10x10 mm body, 108 balls), the LM3S2739-IBZ50-A2T is a surface-mount device. The 56 I/O lines are routed through the BGA array, which typically requires a four-layer PCB with microvias for fanout. Any interface to 3.3 V logic or peripherals needs level translation.","metaTitle":"Texas Instruments LM3S2739-IBZ50-A2T MCU, 50MHz, 128KB Flash","metaDescription":"Texas Instruments LM3S2739-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 64KB SRAM, 108-BGA.","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":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"56","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2739","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.6998","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e578ba8ea9aa738439f0d34e3213a748.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2739-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2739-IBZ50-A2T obsolete?","answer":"This means TI will not qualify it into new designs, but it remains available for existing production through the LTB and surplus channels."},{"question":"Is LM3S2739-IBZ50-A2T compatible with LM3S2739-IBZ50?","answer":"The base product number LM3S2739 is shared, but the suffix -IBZ50-A2T indicates a specific variant. The -IBZ50 suffix typically denotes the 108-BGA package and 50 MHz speed grade. The -A2T suffix may indicate a specific revision or tape-and-reel packaging. Footprint and electrical compatibility should be verified against the datasheet for the exact suffix; TI's PCN history would confirm any silicon revision differences."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2739-IBZ50-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/LM3S2739-IBZ50-A2T when reusing this data.
