MCM69C433TQ15: 16K x 64 CAM ARCHIVED

Overview

The MCM69C433 is EOL. See PCN9049.
Possible replacement: none.

The MCM69C433 is a flexible content–addressable memory (CAM) that can contain 16K entries of 64 bits each. The widths of the match field and the output field are programmable, and the match time is designed to be 240 ns. As a result, the MCM69C433 is well suited for datacom applications such as Virtual Path Identifier/Virtual Circuit Identifier (VPI/VCI) translation in ATM switches up to OC12 (622 Mbps) data rates and Media Access Control (MAC) address lookup in Ethernet/Fast Ethernet bridges. The match duty cycle of the MCM69C433 is user–defined, with a trade–off between the time between matches and the rate of new entries added to the CAM per second.
