MOTOROLA FAST SRAM
Motorola, Inc. 2000
16K x 64 CAM
The MCM69C432 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 180 ns. As a result,
the MCM69C432 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 MCM69C432 is
user defined, with a trade–off between the time between matches and the rate
of new entries added to the CAM per second.
