Its parallel host interface connects directly to the MAC without an SPI bridge, keeping the BOM count low for embedded Ethernet nodes. The 64-TQFP (10x10 mm) footprint fits on compact two-layer boards with careful routing of the differential pairs. Rated for 3V to 3.6V operation, the LAN83C185-JT runs from a single 3.3V supply — no additional 1.8V or 2.5V rail is needed, simplifying the power-tree design. ROHS3 Compliant per, the part meets current environmental restrictions for EU and global markets, with no exemption-based compliance gaps to track.","metaTitle":"LAN83C185-JT Ethernet PHY, 10/100 Base-T/TX, 64-LQFP","metaDescription":"Microchip LAN83C185-JT 10/100 Base-T/TX PHY controller in 64-LQFP. 40mA supply, 3-3.6V, parallel interface.
