WIZ100SR

Overview

The WIZ100SR is a serial-to-Ethernet interface module manufactured by WIZnet. It integrates the W5100 Ethernet controller chip, which features a full hardware TCP/IP protocol stack, to convert RS-232 signals into TCP/IP data for network transmission. The module supports a maximum data rate of 100 Mb/s on the Ethernet side and up to 230 Kbps on the serial side. It operates on a single 3.3 V power supply with a typical current consumption of 200 mA. The physical dimensions are 50 mm x 30 mm x 12 mm, and it functions within a temperature range of 0°C to +80°C. The device supports DHCP, Static IP, and PPPoE configurations.

Feature Summary

• Integrates W5100 chip with full hardware TCP/IP protocol stack for stable connectivity
• Converts RS-232 serial signals to TCP/IP protocol for remote management
• Supports multiple network configuration modes including DHCP, Static, and PPPoE
• Enables simple configuration via serial commands or dedicated tools

Applications

• Remote monitoring and control of serial devices over Ethernet networks
• Industrial automation systems requiring serial-to-Ethernet gateway functionality
• IoT sensor integration into existing LAN infrastructure

Procurement Notes

Verify component status before procurement as the WIZ100SR is classified as NRND (Not Recommended for New Designs). Confirm availability through authorized distributors, noting that stock levels may be limited. Ensure compatibility with existing system requirements given the end-of-life designation. Check for specific RoHS compliance documentation if required for regulatory adherence in target markets.

Selection Notes

Select this module when legacy RS-232 equipment requires network integration without modifying the host device's firmware. The built-in hardware TCP/IP stack reduces MCU load compared to software-based solutions. Consider the 3.3V logic level requirement for interfacing with the serial port. Evaluate alternative models like the WIZ750SR if newer design support or different form factors are needed, as this model is no longer recommended for new designs.
