The 25 MHz core and 48-LQFP footprint are common across the family, so a migration is typically a firmware recompile and a BOM swap. ## Connectivity and peripherals for control applications The LM3S315 integrates UART/USART, SPI, SSI, and Microwire serial interfaces, along with 32 GPIOs. The internal oscillator and WDT simplify the board-level BOM for a compact sensor node or a brushless-DC motor controller. The 4x10-bit ADC provides enough resolution for current-sense feedback or potentiometer inputs.","metaTitle":"LM3S315-IQN25-C2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S315-IQN25-C2 is a 32-bit Stellaris ARM Cortex-M3 MCU with 25 MHz core, 16 KB Flash, 4 KB RAM, 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":"25MHz","Series":"Stellaris® ARM® Cortex®-M3S 300","Package":"Tray","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":"$10.4588","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a7c9be541fa6b753c5531de379c93f41.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S315-IQN25-C2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S315-IQN25-C2 obsolete or still active?","answer":"It is not fully obsolete — existing production can still procure it — but it is not recommended for new design starts.
