Frequently Asked Questions
What is the core clock speed and memory capacity of the LM3S5951-IBZ80-C3?
The LM3S5951-IBZ80-C3 features an ARM Cortex-M3 core clocked at up to 50 MHz, paired with 256 KB of on-chip Flash program memory and 64 KB of SRAM. This combination provides sufficient throughput and storage for real-time control firmware with Ethernet and USB protocol stacks running concurrently.
Which connectivity interfaces does the LM3S5951-IBZ80-C3 integrate for industrial networking?
The LM3S5951-IBZ80-C3 integrates a 10/100 Mbps Ethernet MAC with MII/RMII interface, full-speed USB OTG at 12 Mbps, multiple UARTs, 2 SSI (SPI) ports, and I2C. This peripheral set allows it to serve as an Ethernet-to-serial or Ethernet-to-CAN gateway without external network controllers, reducing BOM cost in industrial router designs.
How does the DMA controller in the LM3S5951-IBZ80-C3 improve data acquisition performance?
The on-chip DMA controller in the LM3S5951-IBZ80-C3 offloads data transfers between the 10-bit ADC, UART, SSI, and SRAM from the Cortex-M3 CPU. This allows continuous ADC sampling at up to 1 Msps while the CPU processes Ethernet packets, achieving throughput levels that would saturate an interrupt-driven design running at 50 MHz.
Is the 108-ball BGA package of the LM3S5951-IBZ80-C3 suitable for standard PCB manufacturing?
The 108-ball BGA package uses a 0.5 mm ball pitch, which requires PCB layer count of at least 4 and via-in-pad or dogbone fanout routing. While it demands more advanced PCB fabrication than LQFP alternatives, it reduces the board footprint to roughly 9 mm x 9 mm, making it practical for space-constrained industrial gateway boards using standard FR4 with 100 µm min trace width.
