It requires two supply rails — 1.8 V for the core logic and 3.3 V for the I/O and PHY — so the board design must budget for both voltages, typically from a dual-output regulator or two separate LDOs. The 288 mA supply current figure covers the full operating state with both USB and Ethernet active; the actual draw varies with link speed and traffic, but this is the number to use for the worst-case thermal budget. ## Package footprint and thermal management Housed in a 64-VFQFN with an exposed pad (supplier device package 64-QFN 9x9 mm), the part requires a thermal via array under the pad to conduct heat into the PCB ground plane — without it, the junction temperature rises above the 70°C ambient ceiling in a confined enclosure. ## Lifecycle and compliance standing The part ships in Tray packaging, which is the standard format for volume assembly — no reel or tape-and-reel variant is listed in this entry.","metaTitle":"LAN9514-JZX USB 2.0 to Ethernet Bridge, 64-QFN","metaDescription":"Microchip LAN9514-JZX USB 2.0 to 10/100 Ethernet controller in 64-QFN.
