DM9051AN – A High-Performance, Energy-Efficient Ethernet Solution that Outperforms W5500
n the context of rapidly growing IoT applications, the demand for an Ethernet solution that is powerful, energy-efficient, and easy to integrate has become increasingly important. Two popular options today are DM9051AN and W5500. So, what makes them different, and why is DM9051AN the top choice for many customers?
Superior Transmission Performance
Tests show that across various MCU/SoC platforms, DM9051AN achieves TCP throughput of 7–11 Mbps, while W5500 only reaches 1–3 Mbps depending on the platform.
=> With such a significant gap, DM9051AN provides a clear advantage in applications requiring stable bandwidth and high speed.
Energy Saving – Cooler Operation
-
DM9051AN: 32mA (10M mode) / 45mA (100M mode), with operating temperature around 30℃.
-
W5500: 75mA (10M mode) / 120mA (100M mode), with operating temperature up to 60℃.
👉 This demonstrates that DM9051AN not only saves power but also ensures a stable, low-heat system, making it ideal for IoT devices that require long-term reliability.
Optimized Design – Lower Cost
-
DM9051AN integrates a built-in MAC address, requiring no external EEPROM, and only about 12 peripheral components.
-
W5500 requires additional EEPROM and up to 27 peripheral components, resulting in a higher RBOM and significantly increased cost.
Moreover, DM9051AN provides better noise immunity and ESD protection, reducing risks in real-world products.
Flexible Software Integration
DM9051AN is already integrated into:
-
Artery AT MCU SDK
-
Espressif ESP32 ESP-IDF
-
Linux driver
-
FreeRTOS (LwIP TCP/IP stack)
Users can adopt it directly without re-developing drivers, saving significant time and effort. In contrast, W5500 relies on its own HW TCP/IP stack, which overlaps with the stronger stacks in Linux/RTOS, resulting in reduced performance.
Conclusion
With outstanding advantages:
-
Higher transmission performance
-
Lower power consumption, cooler operation
-
Simplified RBOM design, lower cost
-
Easy integration across multiple platforms
👉 DM9051AN is the optimal Ethernet solution for IoT applications, a perfect replacement for W5500 in many real-world designs.
