Overview
The Renesas Electronics Corporation 1894KI-44LF is an Ethernet Physical Layer Controller belonging to the PHYceiver™ series. It functions as a 10/100 Base-T/TX PHY with a parallel interface, designed for high-speed data transmission over twisted-pair cabling. The device operates within a supply voltage range of 3.14V to 3.47V and supports data rates of 10 Mb/s and 100 Mb/s. It is housed in a 20-VFQFPN package with exposed pads, measuring 4x4 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.
Feature Summary
- Supports 10/100 Base-T/TX Ethernet standards for reliable network connectivity
- Integrates a single transceiver for physical layer signal processing
- Utilizes a parallel interface for efficient data communication with host controllers
Applications
- Ethernet network interface modules
- Industrial control systems requiring 10/100 Mbps connectivity
- Embedded networking equipment
Procurement Notes
Verify the exact suffix against official documentation, as variations may exist. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly. Check current lifecycle status via manufacturer channels to ensure availability for production.
Selection Notes
Select this component when a dedicated 10/100 Base-T/TX PHY with a parallel interface is required. Ensure the design accommodates the 3.14V to 3.47V supply voltage range and the 20-VFQFPN footprint. Verify thermal management capabilities for the 0°C to 70°C operating temperature range.
Part Context
This part is part of the Renesas PHYceiver™ family of Ethernet controllers. It shares functional similarities with other models like the 1894K-32LFT but differs in pin count and package configuration. The KI suffix typically denotes industrial or extended temperature variants, though specific verification is needed.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official replacement guide for validated alternatives.
