The 25 MHz Cortex-M3 core handles control loops and protocol stacks efficiently, but the memory ceiling means no heavy RTOS or large data buffers. Typical applications include I²C or SPI sensor readout, UART-to-SPI bridging, PWM generation for LED or motor drivers, and simple keypad-and-display interfaces. ## Temperature grade and environment — industrial range without qualification overhead It is not AEC-Q100 qualified, so it is not intended for automotive under-hood or chassis domains. This part is still a valid choice for both new production runs and ongoing repair of existing Stellaris-based designs.","metaTitle":"LM3S308-IGZ25-C2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S308-IGZ25-C2 32-bit ARM Cortex-M3 MCU from the Stellaris 300 series. 25 MHz core, 16 KB Flash, 4 KB SRAM, 28 I/O, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"I²C, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S308","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-VQFN (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90a978bd331b0d8880daa32faecfc169.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S308-IGZ25-C2/alternatives.json"},"ai":{"faq":[{"question":"Can LM3S308-IGZ25-C2 replace a failed LM3S308-IGZ25-C1 without PCB changes?","answer":"Yes, the -C2 variant is pin-compatible and package-identical to the -C1. The 48-VFQFN footprint and all electrical ratings are the same.
