LAN9252TI/PT

Controllers Overview

The LAN9252TI/PT is a 2/3-port EtherCAT slave controller from Microchip Technology, housed in a 64-pin TQFP-EP package. It integrates dual full-duplex 100BASE-TX Ethernet PHYs supporting 100Mbps operation and HP Auto-MDIX. The device features an EtherCAT slave controller with 4K bytes of Dual Port RAM (DPRAM), three Fieldbus Memory Management Units (FMMUs), and four SyncManagers. It supports multiple host interfaces including an 8/16-bit bus, SPI, and Quad SPI. Operating voltage ranges from 1.8V to 3.3V for I/O, with an integrated 1.2V regulator allowing single 3.3V supply operation. The industrial temperature range spans from -40°C to +85°C.

Controllers Feature Summary

• Integrates dual 100BASE-TX Ethernet PHYs with HP Auto-MDIX and distributed clock support for high-precision synchronization.
• Provides flexible connectivity through 8/16-bit Host Bus Interface, SPI, and Quad SPI modes, alongside Digital I/O mode for simple modules.
• Includes comprehensive power management with three power-down levels and multiple wake-on-LAN event triggers.
• Supports 3rd port expansion via MII interface for star or tree network topologies.

Controllers Applications

• Motor Motion Control
• Process and Factory Automation
• Communication Modules and Interface Cards
• Hydraulic and Pneumatic Valve Systems

Controllers Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) and 'PT' denotes the 64-pin TQFP-EP package. Confirm RoHS compliance and lead times directly with authorized distributors. Ensure the design accounts for the exposed pad thermal connection requirements specified in the datasheet.

Controllers Selection Notes

Select this component when an EtherCAT slave solution requires integrated PHYs and flexible host interfacing options like SPI or parallel bus. Consider the 64-TQFP-EP package for board space constraints compared to QFN variants. Verify that the application environment falls within the industrial temperature range and that single 3.3V power supply compatibility meets system requirements.

Controllers Part Context

The LAN9252 series serves as a cost-effective EtherCAT slave controller for industrial automation. The TI/PT variant specifically targets designs requiring the TQFP-EP package form factor while maintaining industrial temperature ratings. It complements other LAN9252 variants differing primarily in packaging and temperature specifications.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip for current alternative recommendations or pin-compatible options if sourcing constraints arise.
