That 165 mW dissipation keeps the junction temperature well below the 85°C ambient ceiling even in a sealed enclosure with limited airflow — no heatsink required for most designs. This qualifies the part for factory-floor automation, outdoor telecom cabinets, and engine-bay-adjacent electronics where the ambient sees -20°C startup and 70°C sustained load. ## 100-TQFP 14x14 mm — layout and fan-out The fine pitch demands a 4-layer PCB for reliable fan-out of the 100 signal and power pins — two-layer boards will struggle to route the parallel bus and decoupling capacitors under the body. The exposed pad on the bottom provides a low-inductance ground return; a thermal via array under the pad improves heat spreading. ## Parallel host interface — direct bus attachment The parallel interface connects directly to most MCU/MPU external memory buses without external glue logic. The 10Base-T PHY handles the analog front-end and auto-negotiation, so the host sees a standard MAC-level register set. This reduces BOM count and layout complexity compared to a separate MAC + external PHY solution. ## ROHS3 compliance — no exemption risk For UKCA and EU market shipments, no additional documentation or exemption justification is needed at the BOM level.","metaTitle":"Microchip LAN91C96I-MU Ethernet Controller, 10Base-T","metaDescription":"Active-production Ethernet controller with integrated 10Base-T PHY, 3.3V, 50 mA, -40°C to 85°C. 100-TQFP.
