That means TI has flagged it for eventual end-of-life — no new sockets should start with it, and existing production lines need a migration plan. ## 25 MHz and 16 KB Flash — sizing the fit The 25 MHz core handles UART polling, basic PWM generation, and sensor reads. ## Industrial temperature and 48-LQFP footprint The 48-LQFP package with a 7x7 mm body is hand-solderable for prototyping and rework. The 36 I/O lines give headroom for a parallel LCD bus, buttons, and LED indicators without multiplexing.","metaTitle":"LM3S310-IQN25-C2 Stellaris ARM Cortex-M3 MCU, 25MHz, NRND","metaDescription":"Texas Instruments LM3S310-IQN25-C2, 32-bit ARM Cortex-M3 MCU, 25MHz clock, 16KB Flash, 4KB RAM, 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":"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":"36","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S310","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":"$9.4126","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ea054ccbe14afdd58f238a43f2cde7e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S310-IQN25-C2/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S310-IQN25-C2?","answer":"No official pin-compatible replacement is listed in the record. The Stellaris family includes higher-density siblings in the same 48-LQFP footprint — for example, parts with 32 KB or 64 KB Flash and the same peripheral set — but a direct pin-for-pin swap requires checking the specific memory and feature variant against the board's layout.
