WIZ750SR-100

Overview

The WIZ750SR-100 is a serial device server module manufactured by WIZnet, designed to bridge UART interfaces with Ethernet networks. It integrates the W7500 microcontroller and IP101GR PHY transceiver within a compact 50 mm x 30 mm footprint. The unit operates on a 3.3V power supply and supports an industrial temperature range from -40°C to +85°C. Key electrical parameters include a maximum baud rate of 921.6kbps for serial communication and 10/100 Mbps adaptive speeds for the Ethernet interface. The module provides five LEDs for status indication, including TCP connection and PHY link monitoring.

Feature Summary

• Integrates W7500 MCU and IP101GR PHY for direct Ethernet-to-UART conversion
• Supports virtual serial port functionality over TCP and UDP protocols
• Includes hardware-level ESD protection on all serial signal lines
• Provides multiple configuration methods via Windows software, Telnet, and Web interfaces

Applications

• Industrial IoT gateway implementation for remote sensor data acquisition
• Legacy RS-232/422/485 equipment network integration
• Embedded system development and debugging via serial console access

Procurement Notes

Verify component authenticity through authorized distributors or official WIZnet channels. Confirm RoHS compliance documentation matches the specific manufacturing batch. Ensure the ordering suffix corresponds to the required packaging format. Request datasheet revision history to validate feature consistency before final procurement decisions.

Selection Notes

Evaluate thermal requirements against the specified -40°C to +85°C operating range for your deployment environment. Assess network topology compatibility with the supported 10/100 Mbps Ethernet standards. Consider the available GPIO expansion headers if additional peripheral control is necessary beyond standard serial communication functions.
