The internal oscillator eliminates the external crystal for most applications, saving two I/O pins. 18 general-purpose I/O lines multiplex with I²C, SPI, SSI, and UART/USART interfaces. The peripheral set is suited for sensor aggregation (I²C for temperature/humidity, SPI for ADCs) and low-speed actuator control via the on-chip PWM generator. Built-in brown-out detect and power-on reset eliminate the external supervisor IC in cost-sensitive designs. The watchdog timer provides a last-resort recovery path for unattended equipment. ## Temperature grade and deployment context The 105°C ceiling gives margin above the typical 85°C industrial grade.","metaTitle":"TI LM3S102-EGZ20-C2T Cortex-M3 MCU, 20MHz, 8KB Flash","metaDescription":"Texas Instruments LM3S102-EGZ20-C2T Stellaris ARM Cortex-M3 MCU, 20MHz, 8KB Flash, 2KB RAM, 18 I/O, -40 to 105°C, 48-VQFN.
