Microchip Small Footprint RMIII Ethernet Controller Transceiver, 10/100Mbps, SQ
Compact Microchip SQFN Ethernet transceiver for 10/100Mbps networks. Ideal for embedded, IoT & industrial designs with wide voltage/temp range.
The Microchip Small Footprint RMIII Ethernet Controller Transceiver is a high-performance, low-power integrated circuit designed for embedded network applications. Featuring a compact SQFN (Small Quad Flat No-lead) package with 24 pins, it provides a space-saving solution for designs where board real estate is at a premium.
This transceiver supports both 10Mbps and 100Mbps data rates, ensuring compatibility with a wide range of networking equipment. It is fully compliant with the IEEE 802.3 and IEEE 802.3u (Fast Ethernet) standards, guaranteeing reliable and interoperable communication in industrial, consumer, and commercial devices. The RMII (Reduced Media Independent Interface) simplifies connection to MAC controllers, reducing pin count and system complexity.
Built for robust operation, it functions across a wide supply voltage range from 1.62V to 3.6V, making it suitable for low-power applications. Its operational reliability is further proven by an extended temperature range from -40°C to +85°C, allowing deployment in harsh environmental conditions. The surface-mount design facilitates automated assembly processes for high-volume manufacturing.
This component is an essential building block for adding Ethernet connectivity to a vast array of products, from IoT sensors and industrial controllers to network switches and automotive modules. Its small footprint and standard compliance make it a versatile and reliable choice for engineers.
