Revision 1.15 – August 30, 2007
Data Sheet
External master interface
- Write posting from external master
- Read prefetching on PLB for external master reads
- Bursting capable from external master
- Allows external master access to all non-EBC PLB slaves
- External master can control EBC slaves for own access and control
Ethernet Controller Interface
Ethernet support provided by the PPC440GX interfaces to the physical layer, but the PHY is not included on the
chip.
Features include:
One to four 10/100 interfaces running in full- and half-duplex modes
- One full Media Independent Interface (MII) with 4-bit parallel data transfer
- Two Reduced Media Independent Interfaces (RMII) with 2-bit parallel data transfer
- Four Serial Media Independent Interfaces (SMII)
One or two GMII interfaces running in full- and half-duplex modes at 10Mb/s or 100Mb/s or 1000Mb/s
- One full Gigabit Media Independent Interface (GMII) with 8-bit parallel data transfer
- Two Reduced Gigabit Media Independent Interfaces (RGMII) with 4-bit parallel data transfer
One or two TBI interfaces running in full- and half-duplex modes at 10Mb/s or 100Mb/s or 1000Mb/s
- One full Ten Bit Interface (TBI) with 10-bit parallel data transfer
- Two Reduced Ten Bit Interfaces (RTBI) with 4-bit parallel data transfer
Jumbo frame support (9016 byte)
- Support for Ethernet II formatted frames (RFC894)
- Support for IEEE formatted frames (RFC1042)
- Handles VLAN-tagged frames
