• Manufacturer Part Number: mcs1000
• Description: Security Processor
• Manufacturer: MosChip

Rev. 1.1
The MCS1000 has three (3) Fast Ethernet controllers. These controllers consist of a MAC and a PHY. The
PHY interfaces are brought off-chip in normal mode (3 PHY mode). The PHYs can be connected directly to
Ethernet magnetics. There are two configurations for the PHYs. The standard configuration brings all three
PHYs to the IC’s pins. In the alternate configuration two PHYs and one MII are brought out to the IC’s pins.
See table below for pin-out details.
