Freescale Semiconductor, Inc. CAMFACT/D Rev. 1 Fa c t S h e e t M OTOROLA C ONTENT- A DDRESSABLE M EMORIES Freescale Semiconductor, Inc... High-Speed Look-Up Engines for Networking Applications The MCM69C232/233 and the MCM69C432/433 are flexible content-addressable memories (CAMs) that can contain 4096 and 16,384 entries of 64 bits, respectively. They are implemented with standard 4-transistor SRAM cells that provide a CAM solution at a fraction of the cost of existing CAMs. The widths of the match field and the output field are programmable, and the match time is designed to be ≤ 180 nanoseconds for MCM69C232/432. As a result, the MCM69C232/233 and the MCM69C432/433 are well suited for datacom applications such as Virtual Path Identifier/ Virtual Circuit Identifier (VPI/VCI) translation in ATM switches up to OC12 (622Mbps) data rates and Media Access Control (MAC) address lookup in Ethernet/Fast Ethernet bridges. CAMs are also well suited for fully associative disk drive cache and RAID applications. The match duty cycle of the MCM69C232/233 and the MCM69C432/433 is user defined, with a trade-off between the time between matches and the number of new entries added to the CAM per second.
