SEMICONDUCTOR TECHNICAL DATA

MCM69C232

Advance Information

4K x 64 CAM

The MCM69C232 is a flexible content–addressable memory (CAM) that can

contain 4096 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 160 ns. As a result,

the MCM69C232 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 MCM69C232 is

user defined, with a trade–off between the time between matches and the num-

ber of new entries added to the CAM per second.
