1893BFILFT

Overview

The 1893BFILFT is an Ethernet PHYceiver integrated circuit manufactured by Renesas Electronics. It supports 10BASE-T and 100BASE-TX standards with a single transceiver capable of full and half duplex operation. The device operates on a 3.3V supply voltage ranging from 3.14V to 3.47V, with a maximum power dissipation of 400mW and a maximum supply current of 160mA. It utilizes an MII interface for data transmission at speeds up to 100 Mb/s. The component is housed in a 56-pin VFQFPN package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated physical layer controller combining MAC and PHY functionality
• Supports standard 10/100 Base-T/TX Ethernet protocols
• Includes built-in auto-negotiation capabilities

Applications

• Industrial networking equipment
• Consumer electronics requiring Ethernet connectivity
