The 25 MHz core delivers adequate throughput for UART/SPI/SSI communication at typical baud rates and for PWM generation with the on-chip peripheral set. ## 48-LQFP package — footprint and reflow considerations Housed in a 48-LQFP with a 7x7 mm body (0.5 mm pitch), the LM3S315-IQN25-C2T is a standard surface-mount package. The 32 I/O lines are accessible on the perimeter leads. The package is compatible with standard lead-free reflow profiles.","metaTitle":"LM3S315-IQN25-C2T Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S315-IQN25-C2T 32-bit ARM Cortex-M3 MCU from TI Stellaris series. 25 MHz core, 16 KB Flash, 4 KB SRAM, 48-LQFP, -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":"25MHz","Series":"Stellaris® ARM® Cortex®-M3S 300","Package":"Tape & Reel (TR)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S315","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2479","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a7c9be541fa6b753c5531de379c93f41.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S315-IQN25-C2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S315-IQN25-C2T?","answer":"For a pin-compatible upgrade path, evaluate other Stellaris or TM4C Cortex-M4 devices in the 48-LQFP package with larger Flash and SRAM — the exact pinout and peripheral compatibility must be verified against the respective datasheets."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S315-IQN25-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S315-IQN25-C2T when reusing this data.
