WIZ810SMJ
WIZ810SMJ
The WIZ810SMJ is a versatile Ethernet module based on the W5100S hardwired TCP/IP chip with integrated PHY and RJ45 (MAG-JACK).
It supports both SPI and Parallel System Bus interfaces, allowing flexible connectivity options for embedded network systems.
With full hardware TCP/IP stack offload and minimal design effort, it is an ideal choice for rapid Ethernet integration.
