1893BKLFT

Overview

The 1893BKLFT is an integrated Ethernet PHYceiver controller manufactured by Renesas Electronics. It supports 10BASE-T and 100BASE-TX standards with a single transceiver operating at data rates of 10 Mb/s and 100 Mb/s. The device utilizes an MII interface and operates within a supply voltage range of 3.14 V to 3.47 V. It features full and half duplex modes, consumes a maximum power dissipation of 400 mW, and draws up to 160 mA of current. The component is housed in a 56-lead VFQFPN package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates physical layer transceiver functionality for 10/100 Mbps Ethernet connections
• Supports standard MII interface for digital connectivity
• Enables both full and half duplex communication modes

Applications

• Ethernet network interface implementations
• Industrial control system networking
• Embedded device connectivity modules

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm exact package and tape specifications. Ensure compatibility with required voltage levels and interface standards before integration. Confirm current manufacturing status and availability through authorized channels as product lifecycle stages may affect long-term sourcing options.

Selection Notes

Select this component when a compact solution for 10/100BASE-TX connectivity is required. The integrated design reduces external component count compared to discrete PHY solutions. Consider the VFQFPN package size and thermal characteristics for PCB layout planning. Verify that the MII interface aligns with the host processor or MAC controller requirements.

Part Context

This part belongs to the 1893B series of Ethernet controllers. It serves as a specialized communication IC within the broader category of networking components. The device is designed to provide reliable physical layer transmission and reception capabilities for standard Ethernet applications in constrained environments.

Replacement Considerations

The 1893BFLFT is listed as an alternative variant within the same product family. Verify pinout compatibility and electrical specifications before substitution.
