GENERAL DESCRIPTION
The MU9C RCP family consists of 4K and 8K x 64-bit Routing Coprocessors (RCPs) with a 32-bit wide data interface. The device is designed for use in layer 2 switches to provide very high throughput address translation using tables held in external RAM.

DISTINCTIVE CHARACTERISTICS
• 4K and 8K x 64-bit words
• 64-bit binary compares
• 35 ns deterministic compare and output time
• 32-bit Data I/O port
• 16-bit Match Address Output port
• Address/Control bus directly controls device operations for faster operation or higher throughput
• Seven selectable mask registers
• Synchronous operation
• Cascadable for increased depth
• Extensive set of control states for flexibility
• JTAG interface
• 100-pin LQFP package; 3.3 Volt operation

APPLICATION BENEFITS
• 28 million IPv4 packets per second supports up to 18 Gb Ethernet or 7 OC-48 ATM ports at wire speed
• Exact match on MAC addresses
• Processes DA and SA within 190 ns, supporting three ports of 1 Gb or 34 ports of 100 Mb Ethernet at wire speed
• Mixed mode L3 and L2 single search engine for two ports at 1 Gb or 29 ports of 100 Mb Ethernet at wire speed
• Directly addresses external RAM containing associated data of any width
• Hardware control states directly address memory and registers; Instruction and Status registers for optional software control
