The -40°C to +105°C temperature range means it handles industrial enclosures and motor-drive compartments without derating. The exposed pad is the ground return — a solid pour on the inner layer keeps the thermal impedance low. 32 GPIO lines are available for sensor inputs, LED drivers, or keypad scanning. Four 10-bit ADC channels handle analog feedback from potentiometers or current-sense resistors without an external converter. Serial interfaces include I²C, SPI, SSI, UART/USART, and Microwire — enough to talk to common peripherals like EEPROM, temperature sensors, or serial LCDs. The UART baud rate at 25 MHz is flexible down to standard 9600/115200. ## On-chip supervisory and system robustness Built-in brown-out detect and power-on reset (POR) monitor the supply rail — no external supervisor IC needed for basic voltage monitoring. The watchdog timer (WDT) recovers the system from firmware hangs, which matters for unattended equipment. PWM outputs are available on-chip for dimming LEDs or driving small DC motors with a simple H-bridge. The internal oscillator runs the core without an external clock source, cutting two components from the BOM. ## Lifecycle and sourcing posture Supplied in tape and reel (TR) packaging for automated pick-and-place.","metaTitle":"Texas Instruments LM3S316-EGZ25-C2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S316-EGZ25-C2T Stellaris ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash, 4 KB RAM, -40 to +105°C, 48-VQFN.
