The Microchip KSZ8081RNA-S4LV02 is a 10Base-T/100Base-TX Ethernet PHY transceiver utilizing RMII v1.2, designed for low-power, space-constrained industrial and consumer applications. Featuring a 24-pin QFN package, it offers 6 kV ESD protection, HP Auto MDI/MDI-X, and LinkMD diagnostics, though it lacks Energy Efficient Ethernet (EEE) and requires software-based configuration for many settings.
