NM7010B+

Overview

The NM7010B+ is a network module integrating the W3150A+ TCP/IP hardwired chip, an Ethernet PHY (IP101A), and a MAG-JACK with an RJ45 connector. It supports 10/100 Base-TX standards with half/full duplex operation and auto-negotiation. The module operates on a 3.3V supply with 5V I/O tolerance and includes hardware protocols for TCP, IP, UDP, ICMP, ARP, PPPoE, IGMP, DLC, and MAC. It provides four independent simultaneous connections via MCU bus or SPI interfaces. Maximum power consumption is 160mA at 3.3V.

Feature Summary

• Integrates TCP/IP hardwired chip, Ethernet PHY, and MAG-JACK
• Supports 10/100 Base-TX with auto-negotiation and crossover detection
• Includes hardware Internet and Ethernet protocol stacks
• Offers both MCU bus and SPI interface options

Applications

• Internet-enabled system development
• Embedded network connectivity solutions
• Industrial control systems requiring Ethernet communication

Procurement Notes

Verify component revisions carefully as the datasheet notes changes in PHY chips (RTL8201CP to IP101A) and associated resistor values between versions. Confirm the specific hardware revision matches your design requirements before integration. Check official documentation for updated part lists and schematic details to ensure compatibility with existing board designs.

Selection Notes

Select this module when rapid Internet integration is required without complex protocol stack implementation. Ensure the host microcontroller supports either parallel bus or SPI communication. Verify that the 3.3V power supply meets the maximum current requirement of 160mA. Consider the physical dimensions and header pin pitch for PCB layout constraints.

Part Context

The NM7010B+ is part of WIZnet's network module lineup designed to simplify Ethernet integration. It builds upon previous modules by incorporating the W3150A+ chip and various PHY options. This module serves as a complete networking solution, reducing development time for embedded applications needing reliable TCP/IP connectivity.

Replacement Considerations

Check for updated PHY components like the IP101A-LF if replacing older RTL8201CP-based units. Verify resistor value changes in the schematic for stable operation. Consult WIZnet for newer module alternatives if the NM7010B+ is discontinued or if enhanced features are needed.
