Allows system designers to reduce significant development time and cost and also complement high atmospheric temperatures

Aircraft, military vehicle and ground-based systems that rely on intelligence, information and secure connectivity to support mission success are enabled by enhanced technology designed to operate in extreme temperatures and environmental events.

Therefore, Microchip Technology has announced its new VSC8540/41 Gigabit Ethernet PHY RMII / RGMII Transceiver – a Commercial-Off-The-Shelf (COTS)-based device upgraded for avionics and military applications.

Based on COTS technology, the Gigabit Ethernet Physical Layer (PHY) transceiver features a military-grade, high-reliability (HiRel) plastic package that meets application requirements ranging from fighting vehicles to cockpit avionics and in-flight communication systems.

Free From Radiation

The VSC8541RT Ethernet transceiver is a solution with Reduced Gigabit Media Independent Interface (RGMII) and G.M.I.I., and also supports R.M.I.I and M.I.I. Megabit interface. The transceiver is latch-up immune to atmospheric radiation effects while performing at a temperature range of –55 to 125 degrees Celsius. Product specifications include wafer and assembly lot full traceability, description of testing, electrical parameters and fault coverage, qualification report and compliance certificate.

As COTS-based technology, Microchip’s Ethernet PHY RMII / RGMII transceiver allows system designers to begin implementation with COTS devices before moving to military-grade components, reducing significant development time and cost.

Microchip’s RMII / RGMII transceiver is the latest high-reliability solution designed for extreme environments, building on the company’s aerospace, defence and space product portfolio. The device complements extended-temperature product offering that includes:

  • 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 VSC8540/41 Gigabit Ethernet PHY RMII / RGMII transceiver in a plastic or ceramic package is now sampling.

Besides introducing innovations including those based on COTS technology, Microchip teams with system manufacturers and integrators on obsolescence management, supporting customers’ efforts to minimize redesign work and lengthen life cycles, thereby reducing overall system costs.
