KSZ8873RLL - 3-Port Ethernet Switch Controller IC

The KSZ8873RLL is a high-performance, low-power 3-port Ethernet switch controller from Microchip Technology, designed for embedded systems, industrial automation, and IoT applications. This advanced IC integrates three 10/100 Base-T/TX PHY transceivers with a managed switch engine, providing reliable network connectivity in a compact 64-LQFP package.

Key Features & Benefits

  • Triple-Port Integration: Three integrated 10/100 Mbps Ethernet PHYs eliminate the need for external transceivers
  • Flexible Interface: I2C and SPI management interfaces for seamless system integration
  • Wide Voltage Range: Supports 1.8V, 2.5V, and 3.3V supply voltages for versatile design compatibility
  • Low Power Consumption: Only 115mA typical current draw for energy-efficient operation
  • Industrial Temperature Range: Operates reliably from 0°C to 70°C
  • Compact Footprint: 64-LQFP (10x10mm) package saves valuable board space
  • RoHS Compliant: Environmentally friendly, lead-free construction

Applications

Ideal for industrial Ethernet switches, embedded network appliances, building automation systems, security cameras, and multi-port IoT gateways requiring managed switching capabilities.
