This covers the common sensor buses (I²C for temperature/humidity, SPI for ADCs or displays) and a debug UART. The SSI port runs synchronous serial for codec or motor-encoder links. The internal oscillator eliminates the external crystal for the core clock, saving two pins and a board footprint — though an external source can still feed the clock tree if tighter timing is needed. ## Industrial temperature range and package — board integration notes The exposed pad also serves as the primary ground return for the core logic; a poor solder joint here can cause intermittent brown-out resets at temperature extremes. ## Active lifecycle — no end-of-life risk for the BOM line No stock-holding claim — availability verified per inquiry.","metaTitle":"TI LM3S300-IGZ25-C2 ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash","metaDescription":"Texas Instruments LM3S300-IGZ25-C2 Stellaris ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash, 4 KB RAM, 36 GPIO, I²C/SPI/UART, -40 to 85°C, active production, quoted to","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":"36","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S300","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":"$3.4567","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b0079ff5b3d77e4f86c3abfcf8857684.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S300-IGZ25-C2/alternatives.json"},"ai":{"faq":[{"question":"How can I order or request a quote for LM3S300-IGZ25-C2?","answer":"Submit an RFQ with your target quantity.
