WIZ750SR-TTL

Overview

The WIZ750SR-TTL is a Serial to Ethernet (S2E) module based on the W7500P chip. It integrates an ARM Cortex-M0 processor with a hardwired TCP/IP stack supporting TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. The module includes an embedded PHY (IC plus IP101G). Dimensions are 48mm width x 30mm length x 18mm height. It features a Micro USB connector for power and communication, compatible with TTL serial interfaces.

Feature Summary

• Hardwired TCP/IP SoC integration
• Embedded PHY support
• TTL serial interface compatibility

Applications

• Serial to Ethernet conversion
• IoT device connectivity
• Industrial automation networking

Procurement Notes

Verify the specific revision of the W7500P silicon used in the current production batch. Confirm that the TTL voltage levels match the target system requirements. Ensure the firmware version supports the required protocol stack features. Check for any hardware revisions affecting the Micro USB connector type or GPIO pinout definitions.

Selection Notes

Select this model when a TTL serial interface is required instead of RS-232 or RS-485. Compare against the WIZ107/108SR series for backward compatibility needs. Evaluate the need for external antenna options if wireless connectivity is required, as this model is wired only. Consider the development board availability for prototyping.

Part Context

This module is part of the WIZnet S2E product line, designed to bridge serial devices to Ethernet networks. It serves as a drop-in replacement for older WIZ107/108SR modules in many applications. The TTL variant specifically targets microcontroller-based systems requiring direct UART connection without level shifting.

Replacement Considerations

WIZ107SR and WIZ108SR are functionally compatible predecessors. Verify pinout and firmware command set differences before substitution.
