WIZ850IO

Overview

The WIZ850io is a compact plug-in network module integrating the W5500 TCP/IP hardwired chip, an embedded PHY, a transformer, and an RJ45 connector. It operates on a 3.3V supply with a range of 2.97V to 3.63V and supports high-speed SPI communication up to 80 MHz. The module features Wake-on-LAN functionality and a power-down mode consuming 13 mA. Its physical dimensions are 23mm x 25mm x 18mm, utilizing two 6-pin 2.54mm headers for connectivity.

Feature Summary

• Integrates W5500 hardware TCP/IP controller with embedded PHY and MAG-JACK
• Supports Wake-on-LAN and low-power shutdown modes
• Hardware compatible with WIZ820io form factor

Applications

• Embedded systems requiring rapid Internet connectivity development
• IoT devices needing stable wired Ethernet connections
• Industrial controllers utilizing hardware TCP/IP offloading

Procurement Notes

Verify that the specific revision matches the target application requirements. Confirm firmware compatibility if migrating from WIZ820io, as hardware changes necessitate software updates. Ensure the host MCU supports the required SPI timing and voltage levels for reliable operation.

Selection Notes

Select this module when a complete Ethernet solution including the transformer and RJ45 is needed without custom PCB design. It is suitable for applications requiring hardware TCP/IP processing to reduce MCU load. Consider the 23mm x 25mm footprint for space-constrained designs.

Part Context

WIZ850io belongs to the WIZnet network module family, which combines iEthernet chips with passive components. It is designed to simplify Ethernet integration by providing a ready-to-use component. The module leverages WIZnet's proprietary hardwired TCP/IP technology to accelerate development cycles.

Replacement Considerations

WIZ850io is hardware compatible with WIZ820io. Migration requires modifying the firmware to accommodate the differences between the modules.
