MU9C Routing CoProcessor (RCP) Family

APPLICATION BENEFITS

DISTINCTIVE CHARACTERISTICS

•

Longest Prefix Match searches of IPv4 addresses

•

4K and 8K x 64-bit words

•

28 Million IPv4 packets per second supports up to 18

Gb Ethernet or 7 OC-48 ATM ports at wire speed

32-bit ternary or 64-bit binary compares

64-bit per word memory organization

35 ns deterministic compare and output time

32-bit Data I/O port

•

Longest Prefix Match searches of IPv4 addresses

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

16-bit Match Address Output port

Address/Control bus directly controls device

operations for faster operation or higher throughput

•

Mixed mode L3 and L2 single search engine for two

ports at 1 Gb or 29 ports of 100 Mb Ethernet at wire

speed

•

Seven selectable mask registers

Synchronous operation

Cascadable for increased depth

Extensive set of control states for flexibility

JTAG interface

•

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

100-pin and 128-pin LQFP packages; 3.3 Volt

operation (also available in lead-free packages)
