MII to RMII convertor for SmartFusion2
Overview
Reduced media independent interface (RMII) is a standard interface which helps in reducing the number of signals required to connect a PHY to a MAC. CoreRMII is responsible for providing the interface between a standard media independent interface (MII) to RMII conversion. The sixteen-signal MII interface is converted into six-signal RMII interface. The IP core adheres to RMII specification v1.2 that has been designed to support the SmartFusion®2 device family. The SmartFusion2 Ethernet MAC (EMAC) supports IEEE 802.3 10/100/1000 Mbps Ethernet operation. Various configuration parameters or generics are applied to CoreRMII core.
Key Features
- Provides reduced pin-count interface for Ethernet PHYs
- Provides MII interface towards the microcontroller subsystem (MSS)-side and RMII interface on the PHY-side
- Supports 25 MHz clock operation on the MII-side and 50 MHz on the RMII-side for 10/100 Mbps mode operation
- Configurable parameter to select the data rate – 10/100 Mbps
- Configurable parameter to enable/disable loopback feature
- Supports full-duplex and half-duplex operations
