LAN9252

In Production

Microchip’s LAN9252 is a 2/3-port EtherCAT slave controller with dual integrated Ethernet PHYs which each contain a full-duplex 100BASE-TX transceiver and support 100Mbps (100BASE-TX) operation. The LAN9252 supports HP Auto-MDIX, allowing the use of direct connect or cross-over LAN cables. 100BASE-FX is supported via an external fiber transceiver. This device provides system developers a cost-effective solution for realizing EtherCAT slaves solutions.

The LAN9252 includes a 3 port EtherCAT slave controller with 4K bytes of Dual Port memory (DPRAM), 4 SyncManagers, 3 Fieldbus Memory Management Units (FMMUs) and a 64-bit Distributed Clock.

It supports 4 Process Data Interfaces - SPI/SQI, HBI and a 16 Bit Digital IO. SPI and SQI (high speed SPI) provide a low pin count synchronous slave interface that facilitates communication between the device and a host system. Whereas, the Host Bus Interface facilitates the same via a high-speed asynchronous slave interface. For simple digital modules without micro-controllers, the LAN9252 can also operate in Digital I/O Mode where 16 digital signals can be controlled or monitored by the EtherCAT master.  The get the most performance from the interface, click here.

The LAN9252 can also be configured to operate via a single 3.3V supply utilizing an integrated 3.3V to1.2V linear regulator. The internal linear regulator may also be disabled, allowing usage of a high efficiency external regulator for lower system power dissipation.

The LAN9252 is available in commercial, industrial and extended industrial temperature ranges and comes in either a 64 pin QFN or a 64 pin QFP-EP.
