On-chip memory comprises 96 KB of Flash (96K x 8) and 64 KB of SRAM (64K x 8). The Flash is sufficient for a moderate application stack plus a bootloader; the SRAM leaves room for a real-time OS heap and data buffers without external memory. ## Package, supply, and temperature grade Housed in a 108-ball LFBGA (10x10 mm body), the 0.80 mm ball pitch demands a multi-layer PCB for fan-out — a four-layer board with microvias is typical for this footprint. The supplier device package is 108-BGA (10x10). On-chip peripherals include a brown-out detect/reset, POR, PWM, and a watchdog timer. Two 10-bit ADCs handle analog inputs without an external converter for basic sensor acquisition.","metaTitle":"TI LM3S1512-IBZ25-A2T Cortex-M3 MCU, 25 MHz, 96 KB Flash","metaDescription":"Texas Instruments LM3S1512-IBZ25-A2T Stellaris ARM Cortex-M3 MCU, 25 MHz, 96 KB Flash, 64 KB 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":"25MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","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":"I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"58","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 2x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1512","Program Memory Size":"96KB (96K 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":"$15.3025","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ff955284a6be074dc752bb03d5753397.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1512-IBZ25-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S1512-IBZ25-A2T in this microcontroller family?","answer":"The Stellaris family includes higher-performance Cortex-M3 parts in the same 108-BGA footprint, but pin compatibility varies by peripheral set and memory size — confirm the BOM position before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S1512-IBZ25-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/LM3S1512-IBZ25-A2T when reusing this data.
