Transceivers (PHYs)

Microchip's 10/100/1000 Mbps Ethernet PHYs are high-performance, small-footprint, low-power 10Base-T/100Base-TX/1000Base-T transceivers designed specifically for today's consumer electronics, industrial, and enterprise applications. These devices feature Energy Efficient Ethernet (IEEE 802.3az) and Wake-On-LAN functionality, which provide system Sleep modes for improved power savings. These devices have the industry's smallest footprint and consume up to 40% less power than existing transceivers. They have an integrated voltage regulator and Electrostatic Discharge (ESD) protection components to help reduce the Bill of Material (BOM) costs.

Ethernet Controllers

Microchip's Ethernet 10/100 controllers include an integrated Ethernet MAC and PHY with a high-performance SRAM-like Slave interface as well as support for external Media Independent (MII) and Peripheral Component Interconnect (PCI) interfaces. The simple yet highly functional host bus interface provides a glueless connection to most common 16-bit MPUS and MCUs as well as 32-bit MPUs with a 16-bit external bus. The controllers are also available with variable I/O voltages and multiple package options.

USB to Ethernet Bridge Controllers

The USB to Ethernet connection takes advantage of the ubiquity and speed of USB, replacing older means of transferring information. USB-based networking technology offers a cost-effective and smart design alternative to traditional PCI/PCI-Express networking solutions due to the flexibility of routing and placement of Ethernet and USB connectivity ports. Microchip integrates Hi-Speed USB 2.0 and high-performance 10/100 Ethernet in its line of standalone USB to Ethernet controllers and USB to Ethernet Hub controllers.

Switches

Microchip's switches are high-performance, small-footprint, full-featured three- to nine-port Ethernet switches. Applications ranging from IoT consumer electronics, computing, Industry 4.0 factory automation, and automotive designs are supported with innovative features and robust high-temperature operation. Rapid development cycles and low-cost are enabled through our design check services and software drivers.

Direct/Standalone Applications

The basic functionality of a switch is to connect multiple Ethernet devices to each other, forming a network. Switches help facilitate the grouping of multiple Ethernet devices that communicate in Full Duplex mode.

Indirect Applications

Switches can also be used in more indirect applications:

  • Set Top Box
    • Many set-top boxes have Wired and Wireless Ethernet connections. The simplest way to do this is to use a three-port switch. One with a PHY going to a wired connection, another MAC going to a wireless receiver, and the final MAC going to the System On Chip (SoC) that controls the set-top box or TV controller.
  • Voice Over IP (VOIP)
    • With VOIP systems, there is usually an Ethernet port and an Internet port with the SoC filtering off the VOIP data to use with a regular phone. This requires a switch to implement.
  • Industrial Control
    • In industrial systems, rugged and redundant Ethernet connections are desired due to the cost of having to put the lines down to fix a break. It also ensures that all devices are connected to a system for proper operation.
  • SoC to SoC Communication
    • Ethernet is also useful as a good SoC to SoC bridge since all software is already compatible with the Ethernet standard.

EtherCAT®

Ethernet for Control Automation Technology (EtherCAT®) is a high-performance Ethernet-based Fieldbus system. Its main development goal was to apply Ethernet to automation applications which require short cycle times and low communications jitter.

The EtherCAT protocol is an open standard currently managed by the EtherCAT Technology Group.

Microchip Technology, a leading provider of MCU, analog mixed-signal, and Flash-IP solutions, strengthens its commitment to the industrial space with the licensing of the EtherCAT technology for next-generation Ethernet controllers.
