It supports both MII and RMII interfaces, giving the system architect flexibility to trade pin count against throughput — RMII uses half the data lines, freeing GPIOs on the MAC side. The supply voltage range of 3V to 3.6V lets it run from a single 3.3V rail without a separate regulator for the core, simplifying the power tree. The industrial temperature grade (-40°C to 85°C) suits outdoor telecom cabinets, factory-floor controllers, and automotive infotainment backbones where ambient heat spikes. ## Package and footprint for PCB layout Housed in a 36-VFQFN with exposed pad (6x6 mm), the LAN8700IC-AEZG requires a thermal land pattern on the PCB to sink heat from the PHY's analog front-end. The exposed pad must be connected to the ground plane with multiple vias to keep junction temperature within the -40°C to 85°C window under continuous 100BASE-TX traffic. Surface-mount assembly with a tray carrier — no tape-and-reel, so plan for pick-and-place nozzle changeover if your line is reel-only. The 0.5 mm pitch QFN demands a solder-paste stencil aperture that matches the pad dimensions in the datasheet footprint drawing. ## Lifecycle and sourcing posture This is a current catalog part, not a legacy or NRND device, so long-term BOM stability is assured without a forced redesign. ROHS3 compliant, no exemption conflicts for EU or California market shipments. The part is sourced through authorized distribution channels; pricing and lead time are confirmed per RFQ against your target quantity.","metaTitle":"LAN8700IC-AEZG Transceiver","metaDescription":"Microchip LAN8700IC-AEZG Ethernet transceiver, full duplex, MII/RMII interface, 3V-3.6V supply, -40°C to 85°C, 36-VFQFN.
