KE5BLME064 Datasheet PDF - KAWASAKI MICROELECTRONICS

Overview
KL5BLME064 is a search device for 40-bit IP address searches in IP routing applications. Its capability extends beyond a simple lookup of data entries stored in a routing table. With its compatibility with the CIDR (Classless Inter-Domain Routing), it outputs associated data for the longest match data when there are multiple matching entries. KE5BLME064 also has the search capability of finding the exact 40-bit match for searching the host address.
