Frequently Asked Questions
What is the core clock frequency and Flash size of the LM3S9DN6-IQC80-A2?
The LM3S9DN6-IQC80-A2 runs the ARM Cortex-M3 core at 80 MHz and provides 512 KB of internal Flash memory, giving it sufficient headroom for TCP/IP stacks, RTOS kernels, and application firmware without requiring external program memory on the PCB.
Which industrial network protocols can the LM3S9DN6-IQC80-A2 support through its peripheral set?
The device integrates an Ethernet MAC/PHY for 10/100 Mbps networking alongside UART, SPI, I2C, and CAN peripherals, allowing a single chip to bridge between factory-floor sensors over serial buses and upstream supervisory systems over Ethernet using standard protocols such as Modbus TCP or EtherNet/IP.
How does the 100-LQFP (14×14 mm) package of the LM3S9DN6-IQC80-A2 compare to smaller QFN alternatives for PCB layout?
The 100-LQFP package with 0.5 mm pitch occupies a 14×14 mm body and has exposed leads on four sides, simplifying hand-soldering inspection and rework compared to QFN packages. However, it requires more board area than a 10×10 mm QFN, so designers prioritizing footprint should consider whether 72 GPIO plus on-chip Ethernet justify the larger outline.
Does the LM3S9DN6-IQC80-A2 include DMA and what benefit does that provide for sensor-data acquisition?
Yes, the LM3S9DN6-IQC80-A2 includes a DMA controller with multiple channels that can move ADC sample bursts from the converter FIFO to SRAM without CPU intervention, freeing the 80 MHz Cortex-M3 core for real-time control loops while sustaining high sample rates across 8 or more ADC input channels simultaneously.
