MCM69C432TQ20 Description

Short technical summary and product information.

The MCM69C432TQ20 from NXP Semiconductors (formerly Motorola) is a Fast SRAM Content Addressable Memory (CAM) with 16K entries of 64 bits each, providing a total memory size of 1Mbit. It offers a programmable match field and output field widths, with a fast match time of 180 ns. The device operates at a maximum clock rate of 50 MHz and requires a single 3.3V supply.

 

This CAM is well-suited for datacom applications such as Virtual Path Identifier/Virtual Circuit Identifier (VPI/VCI) translation in ATM switches and Media Access Control (MAC) address lookup in Ethernet bridges. It supports concurrent matching of virtual path and virtual connection circuits in ATM mode and includes a mask register for ignoring selected bits.

 

The MCM69C432TQ20 is housed in a 100-pin TQFP package and is designed for surface mounting. It also features an IEEE 1149.1 Test Port (JTAG) for testing purposes. The operating temperature range is 0°C to 70°C (TA).
