1893CFLFT

Overview

The 1893CFLFT is an integrated Ethernet PHYceiver manufactured by Renesas Electronics, designed for 10BASE-T and 100BASE-TX standards. It operates on a single 3.3V supply voltage and supports data rates of 10 Mb/s and 100 Mb/s. The device features one transceiver with MDI, MDI-X, and MII interface types. Housed in a 48-SSOP package (7.50mm width), it functions within a commercial temperature range of 0°C to +70°C. This component serves as a physical layer controller for network connectivity applications.

Feature Summary

• Integrated physical layer controller supporting 10/100 Base-T/TX Ethernet standards
• Single transceiver design with parallel interface compatibility
• Operates on a standard 3.3V power supply

Applications

• Network Interface Card (NIC) designs
• PC motherboard integration
• Industrial equipment networking

Procurement Notes

Verify the specific suffix 'FLFT' against official Renesas documentation to confirm RoHS compliance and lead-free status. Confirm the package type matches the 48-SSOP specification required for your PCB layout. Check current product lifecycle status as older variants may be discontinued or subject to last-time buy notices.

Selection Notes

Select this component when a dedicated 10/100 Mbps Ethernet PHY is required for cost-sensitive embedded systems. Ensure the design accommodates the 48-SSOP footprint and 3.3V logic levels. Compare against the broader 1893C series if industrial temperature ranges (-40°C to 85°C) are needed, which may require different suffixes.

Part Context

This part belongs to the Renesas 1893C series of Ethernet PHYceivers. It is functionally related to variants like ICS1893BFT and 1893CKILFT, though package and temperature ratings differ. The 1893CFLFT specifically denotes the commercial grade version in the SSOP package.

Replacement Considerations

The ICS1893BFT is listed as a parameter-equivalent alternative, though it is also marked as obsolete. Verify pinout compatibility and electrical specifications before substitution.
