WIZ810Sio is the internet offload network module that includes W5100S (TCP/IP hardwired chip, include PHY), MAG-JACK (RJ45 with X’FMR) with other glue logics. It can be used as a component and no effort is required to interface W5100S and Transformer. The WIZ810Sio is an ideal option for users who want to develop their Internet enabling systems rapidly.



The WIZ810Sio is a streamlined, powerful network module optimized for fast development of Internet-enabled devices. It features the W5100S chip, offering a fully integrated TCP/IP stack and PHY for seamless networking capabilities. This module comes equipped with a MAG-JACK (RJ45 with transformer), providing an easy-to-use solution that requires minimal effort to interface with the W5100S and transformer. Its support for a wide array of Internet protocols and its compact form factor make it an excellent choice for developers looking to quickly enhance their products with Internet connectivity. Key Specifications: Core: W5100S (TCP/IP hardwired chip, includes PHY) Interfaces: SPI; Ethernet through RJ45 Network Performance: Supports 4 independent sockets simultaneously, half/full duplex operation, Wake on LAN over UDP Operational Temperature: -40 to 85°C Size: 23 x 25 x 23.5 mm Features: Supports major Internet protocols including TCP, UDP, ICMP, IGMPv1/v2, IPv4, ARP, PPPoE; high-speed SPI interface; integrated 10BaseT/100BaseTX Ethernet PHY; auto-negotiation and Auto-MDIX; power-saving modes; 16KB internal memory for TX/RX buffers Description: The WIZ810Sio network module is designed to facilitate quick and easy Internet integration into a wide range of devices. By incorporating the W5100S chip and a convenient MAG-JACK connector, it allows for straightforward network connectivity without the need for complex interfacing. The module supports essential Internet protocols such as TCP, UDP, IPv4, and ARP, along with power efficiency features like Ethernet power-down mode and main clock gating. Its capability to support four independent sockets simultaneously ensures versatile network communications. With a very small footprint and 3.3V operation compatible with 5V I/O signals, the WIZ810Sio is well-suited for applications where space and power efficiency are critical. Applications: This module is ideal for developers seeking rapid deployment of network functionality
