The 32 general-purpose I/O pins give enough headroom for a parallel LCD interface, a row-column keypad, and a handful of discrete status LEDs without needing an external GPIO expander. ## Package, temperature, and board-fit realities The operating temperature range of -40 to 85°C covers most industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics that see ambient heat soak but not direct exhaust. Supply voltage spans 3.0 to 3.6 V, so it runs comfortably off a 3.3 V rail — common in mixed-signal boards where the same rail powers the ADC reference and the sensor bridge. ## On-chip peripherals for a lean BOM The 4-channel 10-bit ADC samples at rates adequate for slow-moving analog signals — thermistor inputs, potentiometer feedback, or battery voltage monitoring. The PWM output, combined with the brown-out detect and watchdog timer, forms a basic safety watchdog for a motor drive or heater controller: if the firmware hangs, the WDT resets the core and the PWM outputs go to a safe state. Serial connectivity includes I²C, SPI (via SSI), Microwire, and UART/USART — enough to talk to a standard set of peripherals: an I²C temperature sensor, an SPI flash for data logging, and a UART-to-USB bridge for debug output. The Microwire compatibility is a legacy bonus if the BOM carries an older EEPROM or ADC that uses that protocol. ## Lifecycle and sourcing posture That means it is still a valid choice for new designs and existing BOM lines alike, with no forced migration pressure.","metaTitle":"Texas Instruments LM3S316-IGZ25-C2T ARM Cortex-M3 MCU, 25MHz","metaDescription":"Texas Instruments LM3S316-IGZ25-C2T Stellaris ARM Cortex-M3 MCU, 25MHz, 16KB Flash, 4K x 8 RAM, 32 I/O, 4x10b ADC, -40 to 85°C, VQFN-48.","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":"Tape & Reel (TR)","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":"32","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S316","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/390a0dd8f415a72ded60f3709e1ec55a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S316-IGZ25-C2T/alternatives.json"},"ai":{"faq":[{"question":"What package does the LM3S316-IGZ25-C2T come in?","answer":"It is supplied in a 48-VFQFN exposed-pad package (7x7 mm body), surface-mount only.
