WIZnet’s Hardwired TCP/IP solution separates the network protocol programming from the MCU. This reduces a lot of workload from the MCU section.
Therefore we wanted to show you the performance on comparing with normal software build TCP/IP code. (For more information, please refer the link below)
Testing method: same platform and delivery package but different Ethernet modules for loopback speed test
Results:
Using W5100S with RP2040 @133MHz, SPI 33MHz,
Link Speed/10Mbps average performance was 2.39Mbps after 10 cycles Send/Recv
Using LAN8720 with [email protected], RMII 50MHz,
Link Speed/10Mbps average performance was 0.322Mbps after 10 cycles Send/Recv
This result shows the WIZnet’s hardwired TCP/IP solution is providing a stable communication platform and reducing MCU’s workload for processing software TCP/IP protocol.
