WIZ145SR

Overview

The WIZ145SR is a serial-to-Ethernet module manufactured by WIZnet Inc. It integrates an ARM-based 32-bit MCU with the WIZ145SR chip to facilitate RS-232 connectivity over Ethernet networks. The device operates on a 3.3 V power supply and supports interface types including Ethernet and RS-232. Its physical dimensions are 61.4 mm x 48.26 mm x 24.7 mm, and it functions within a temperature range of 0°C to +70°C. The unit weighs approximately 653.740 g.

Feature Summary

Integrates an ARM-based 32-bit microcontroller for processing serial data
Provides direct RS-232 to Ethernet conversion capabilities
Includes built-in TCP/IP protocol stack support via the WIZ145SR chip

Applications

Interface development and evaluation for serial-to-Ethernet projects
Prototyping embedded systems requiring RS-232 network connectivity
Testing communication protocols in industrial automation environments

Procurement Notes

Verify current availability status as the product may be discontinued or subject to limited supply constraints. Confirm that the specific revision matches project requirements before ordering. Check for any product change notifications regarding component substitutions or manufacturing updates. Ensure compatibility with existing evaluation software tools provided by the manufacturer.

Selection Notes

Select this module when evaluating hardware solutions for converting legacy RS-232 devices to Ethernet networks using an ARM architecture. Consider the physical size and weight constraints of the enclosure during integration. Verify that the operating temperature range meets the environmental conditions of the deployment site. Ensure the 3.3 V power supply aligns with the system design specifications.

Part Context

The WIZ145SR serves as the core component for the WIZ145SR-EVB evaluation board. This combination allows developers to test and validate serial-to-Ethernet functionality before finalizing a custom PCB design. The module represents a dedicated solution for integrating ARM-based processing with wired network connectivity in embedded applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available. The product documentation indicates discontinuation or restricted supply status. Designers should evaluate alternative WIZnet modules with similar ARM architectures and RS-232 interfaces if replacement is necessary.
