Frequently Asked Questions
What CPU core and clock frequency does the LM3S2776-IQR50-A0 use, and what throughput can it achieve?
The LM3S2776-IQR50-A0 uses a 32-bit ARM Cortex-M3 core running at up to 50 MHz, delivering 50 DMIPS of peak throughput. This is sufficient for running TCP/IP stacks, PID control loops at several kHz, and real-time data logging simultaneously, making it versatile for networked embedded systems.
Does the LM3S2776-IQR50-A0 include an Ethernet interface, and what does that mean for system design?
Yes, the device integrates a full 10/100 Ethernet MAC and PHY, supporting IEEE 802.3 at 10 Mbps and 100 Mbps. This eliminates the need for an external PHY chip, reducing BOM cost by roughly 2–5 components and simplifying PCB routing for applications such as industrial gateways, SCADA nodes, and smart-metering infrastructure.
How many ADC channels does the LM3S2776-IQR50-A0 provide, and what is the resolution?
The integrated ADC offers up to 8 input channels at 10-bit resolution, with a maximum sample rate of 1 MSPS. This allows simultaneous monitoring of multiple analog sensors—voltage, current, temperature, or pressure—at high speed without requiring an external ADC, keeping the design compact and cost-effective.
Which industrial and IoT applications are best served by the LM3S2776-IQR50-A0?
The LM3S2776-IQR50-A0 targets networked industrial controllers, SCADA remote terminal units, and building-automation panels that need Ethernet plus real-time analog acquisition. Its 50 MHz Cortex-M3 core handles lightweight TCP/IP stacks, Modbus/TCP, and BACnet protocols, and the DMA controller ensures data throughput does not stall the CPU during burst transfers of sensor data.
What package does LM3S2776-IQR50-A0 use, and how does it compare to a larger package option for thermal management?
The LM3S2776-IQR50-A0 is supplied in a 100-pin LQFP package with a 14 mm × 14 mm body, offering a compact footprint suitable for space-constrained boards. The exposed thermal pad transfers heat to the PCB plane; at 50 MHz and 3.3 V supply, typical junction temperature rise is well within the 0°C to 70°C commercial range without a heatsink in most designs.
