Frequently Asked Questions
What is the maximum clock frequency of the LM3S317-IQN25-C2T and how many GPIO lines does it provide?
The LM3S317-IQN25-C2T operates at a maximum clock frequency of 25 MHz and provides 30 GPIO lines in the 48-pin LQFP package. This combination supports a wide range of peripheral connections, including SPI, I2C, UART, and analog inputs, within a single compact MCU.
How does the LM3S317-IQN25-C2T fit into a compact motor control or building automation design using a 48-pin LQFP footprint?
The 48-pin LQFP package measures approximately 7 mm x 7 mm with a 0.5 mm pin pitch, fitting standard PCB footprints and enabling high-density board layouts. With 30 GPIO lines, an integrated ADC, and a 25 MHz Cortex-M3 core, it handles PWM generation, sensor sampling, and serial communication without requiring additional MCU resources.
When would the LM3S317-IQN25-C2T be chosen over an LM3S1 series part with higher clock speed?
The LM3S317-IQN25-C2T at 25 MHz is preferable when power consumption matters more than raw throughput, such as in battery-backed control panels or energy-metering devices. The lower clock ceiling reduces dynamic power draw while the 32-bit ARM Cortex-M3 core still outperforms 8-bit alternatives for tasks like floating-point-heavy PID loops or packet parsing at baud rates up to 921600 bps.
