WIZnet TCP/IP Chips & MCUs for Embedded Ethernet
WIZnet’s hardwired TCP/IP controllers and MCUs enable reliable Ethernet connectivity for embedded systems, industrial automation and IoT applications. Hardware-based processing of the TCP/IP stack reduces the load on the host processor and minimises the software overhead for network communication. The portfolio comprises Ethernet controllers with integrated TCP/IP, MAC and PHY, as well as MCU-based solutions for compact embedded designs. Depending on the series, interfaces such as SPI and support for IPv4 and IPv6 are available. Typical applications include industrial control systems, sensor technology, gateways, smart metering, building automation, remote monitoring and networked IoT devices.
