VSC8541ET/41ET Ethernet Transceiver

Microchip Technology Inc. has introduced the new VSC8540/41ET Gigabit Ethernet PHY RMII / RGMII Transceiver, a Commercial-Off-The-Shelf (COTS) based device for avionics and military applications. The new device comes in a military-grade, high-reliability (HiRel) plastic package, which is essential for various applications such as fighting vehicles to cockpit avionics and in-flight communication systems.

The VSC8541ET Ethernet transceiver has been designed with Reduced Gigabit Media Independent Interface (RGMII) and GMII, and also supports RMII and MII Megabit interface. The new transceiver can operate at a temperature range of -50°C to 125°C and it is latch-up immune to atmospheric radiation effects.

Features of VSC8541ET/41ET Ethernet Transceiver

  • 8-bit AVR® microcontrollers with embedded ADC/DAC, Controller Area Network (CAN), and motor control interfaces
  • 16-bit dsPIC® digital signal controller for digital power management
  • 32-bit ARM microcontroller with memory protection mechanisms, and 100 Mbit Ethernet connectivity
  • 200 Mega samples Per Second (Msps) standalone 16-bit ADC

The RMII/RGMll transceiver has been designed to withstand extreme environments with reliability, hence they were built on the company’s aerospace and defense product portfolio. As a COTS-based device, the new transceivers allow the designers to begin implementation with COTS devices before moving to military-grade components, this reduces significant development time and cost.
