WIZ750SR-110

Overview

The WIZ750SR-110 is a serial-to-Ethernet module based on the W7500P hardwired TCP/IP SoC. It integrates an ARM Cortex-M0 core and an embedded PHY (IC plus IP101G). The device supports RS232, RS485/422, and TTL serial interfaces. It operates within a temperature range of 0°C to 80°C and requires a 5V power supply. The module provides one serial port with a maximum baud rate of 230 kbps. It supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols via its hardwired stack.

Feature Summary

• Integrates a hardwired TCP/IP stack supporting multiple standard network protocols without external software overhead.
• Combines an ARM Cortex-M0 processor with an embedded Ethernet PHY for a compact single-chip solution.
• Offers compatibility with existing WIZ107/108SR S2E modules through hardware and software alignment.

Applications

• Industrial automation systems requiring serial device connectivity over Ethernet networks.
• Remote monitoring applications utilizing Modbus RTU or ASCII protocols.
• Embedded system internet integration for data acquisition and control.

Procurement Notes

Verify the specific interface variant required, as the WIZ750SR series includes TTL, RS232, and RS485/422 versions. Confirm that the -110 suffix corresponds to the desired physical connector or pinout configuration. Ensure the operating environment stays within the specified 0°C to 80°C thermal limits. Check for RoHS compliance status if environmental regulations apply to the deployment.

Selection Notes

Select this module when a drop-in replacement for WIZ107/108SR is needed with enhanced processing capabilities. Choose the WIZ750SR-110 if the application demands a 5V supply and specific serial voltage levels. Consider the integrated PHY and memory buffer to simplify PCB design compared to discrete MAC/PHY solutions. Evaluate the need for hardwired protocol support versus software-based stacks in resource-constrained microcontrollers.

Part Context

This component belongs to the WIZ750SR family of serial-to-Ethernet converters manufactured by WIZnet Inc. It utilizes the W7500P chip, which represents a generation of hardwired TCP/IP controllers designed to reduce MCU load. The product line emphasizes ease of implementation for embedded internet connections using simple socket programming interfaces.

Replacement Considerations

The WIZ750SR is explicitly documented as compatible with WIZ107 and WIZ108SR modules. Verify pin mapping and firmware behavior when substituting these older models. No other third-party substitutes are confirmed in the provided documentation.
