Ethernet Controllers

High-Performance Ethernet ICs

Our Ethernet 10/100 controllers include an integrated Ethernet MAC and PHY with a high-performance SRAM-like client interface, as well as support for external MII and PCI interfaces. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bit external bus. The controllers are also available with variable I/O voltages and multiple package options.

Key Features

  • Optimized for high-performance applications
  • Efficient architecture with low CPU overhead
  • Easily interfaces to most 16-bit embedded CPUs
  • 1.8V to 3.3V variable voltage I/O accommodates wide range of I/O signaling without voltage level shifters
  • Integrated PHY with HP Auto-MDIX support
  • Integrated checksum offload engine helps reduce CPU load
  • Low pin count and small body size package for small-form-factor system designs
