LAN9254T-I/JRX

Controllers Overview

The LAN9254T-I/JRX is an Ethernet IC designed as a 2/3-Port EtherCAT Slave Controller with integrated Ethernet PHYs and 32 Digital I/Os. Manufactured by Microchip Technology, it supports high-speed communication for industrial automation networks. The component operates within a temperature range of -40°C to +85°C and utilizes an 80-TQFP-EP (12x12) package. It integrates standard 10/100 Base-T/TX PHY functionality alongside SPI interface capabilities for system control.

Controllers Feature Summary

• Integrates 2/3-port EtherCAT slave controller logic with built-in Ethernet physical layer transceivers
• Provides 32 dedicated digital input/output channels for direct peripheral interfacing
• Supports high-speed communication protocols required for industrial fieldbus applications

Controllers Applications

• Industrial automation systems requiring EtherCAT slave connectivity
• Machine control units needing integrated digital I/O management
• Networked sensor and actuator interfaces in factory environments

Controllers Procurement Notes

Verify the specific ordering suffix JRX against the manufacturer's current datasheet to ensure correct package and temperature grade alignment. Confirm that the 80-TQFP-EP footprint matches the target PCB design. Check for recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement orders.

Controllers Selection Notes

Select this component when a combined solution for EtherCAT communication and extensive digital I/O is required. It eliminates the need for separate PHY and GPIO controllers. Ensure the application environment falls within the specified industrial temperature range and that the TQFP-EP package thermal characteristics are compatible with the system layout.

Controllers Part Context

This part belongs to the LAN9254 family of Ethernet controllers from Microchip Technology. It is distinct from the LAN9253 series which lacks the integrated digital I/O features. The LAN9254T variant specifically denotes the industrial temperature grade and tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

Controllers Replacement Considerations

Direct substitutes include other members of the LAN9254 family such as the LAN9254T-V/JRX for different temperature grades. Cross-model replacements like the LAN9253T require verification of missing digital I/O capabilities. Always validate pinout compatibility and firmware support before substituting.
