Frequently Asked Questions
What is the maximum CPU clock frequency of the LM3S1816-IQR50-C3?
The LM3S1816-IQR50-C3 operates its ARM Cortex-M3 core at up to 16 MHz. This clock speed provides sufficient throughput for real-time control loops, sensor data processing, and communication protocol handling without requiring an external oscillator in many designs.
Which industrial control designs benefit most from the LM3S1816-IQR50-C3 at 16 MHz on a 3.3 V supply?
Motor control, HVAC regulation, and factory-floor sensing nodes benefit most. The 32-bit Cortex-M3 core at 16 MHz handles PID loops efficiently, the on-chip ADC digitizes analog sensor signals up to the converter resolution, and the DMA channels move sampled data to memory at full speed without stalling the CPU, all from a standard 3.3 V rail.
How many I/O pins and what package does the LM3S1816-IQR50-C3 use?
The LM3S1816-IQR50-C3 is housed in a 64-pin LQFP (S-PQFP-G64) package. This configuration provides a practical balance of I/O lines and board area, fitting on a compact PCB while exposing enough pins for multiple UART, SPI, I2C, and ADC signals simultaneously.
Does the LM3S1816-IQR50-C3 include DMA support, and how does it help system performance?
Yes, the LM3S1816-IQR50-C3 includes DMA channels. The DMA controller handles data transfers between peripherals and SRAM independently of the Cortex-M3 core at 16 MHz, reducing interrupt overhead and enabling continuous ADC sampling pipelines with near-zero CPU intervention in typical 32-bit embedded applications.
