Status: 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 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.
