It is not a high-speed control or DSP-class part — the 16 KB Flash limits firmware complexity to a single control loop or a basic protocol stack. For designs that need more headroom, a pin-compatible Stellaris sibling with higher Flash density and clock speed would be the natural upgrade path. The LM3S310-EQN25-C2 is listed as Obsolete. New designs should not target this MCU — instead, evaluate the current-generation Stellaris or Tiva C Series devices for a pin-compatible and software-portable alternative.","metaTitle":"LM3S310-EQN25-C2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S310-EQN25-C2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 300 series. 25 MHz, 16 KB Flash, 4K x 8 RAM, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","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~105°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdef0478df91eed4b7a3abae6c372c23.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S310-EQN25-C2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S310-EQN25-C2 obsolete?","answer":"Yes, the LM3S310-EQN25-C2 is listed as Obsolete.
