1893BFLF

Overview

The 1893BFLF is an Ethernet PHY integrated circuit manufactured by Renesas Electronics, belonging to the PHYceiver series. It supports 10BASE-T and 100BASE-TX standards with a single transceiver capable of full and half duplex operation. The device operates within a supply voltage range of 3.14 V to 3.47 V and functions at data rates of 10 Mb/s and 100 Mb/s. It utilizes an MII interface for connectivity and is housed in a VFQFPN-56 package designed for surface mount installation. The component is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated physical layer controller supporting standard Ethernet protocols
• Supports both full and half duplex communication modes
• Designed for surface mount technology applications

Applications

• Ethernet network interface design
• Industrial communication systems
• Consumer electronics networking modules

Procurement Notes

Verify the specific suffix 'LF' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Confirm the exact package type and pinout configuration required for your PCB layout before ordering. Check current availability as distribution status may vary.

Selection Notes

Select this component when a single-port Ethernet PHY with MII interface is required. Ensure the system power supply aligns with the specified 3.14 V to 3.47 V range. Consider the thermal requirements for the -40°C to +85°C operating environment during board design.

Part Context

This part belongs to the Renesas 1893B series of Ethernet PHY controllers. It is distinct from other variants like the ICS1893BFT which uses a different package and temperature rating. The 1893BFLF specifically denotes the lead-free version in the VFQFPN-56 package.

Replacement Considerations

Consult official Renesas substitution guides for parameter-equivalent alternatives. Verify compatibility with existing firmware and hardware interfaces if replacing with similar PHY devices.
