MU9C4485L General Description
The MU9C4485A/L, MU9C2485A/L, and MU9C1485A/L WidePort LANCAMs are 64-bit wide content-addressable memories (CAMs), featuring a 32-bit wide interface. This interface doubles the available I/O bandwidth in many applications while maintaining the same powerful enhanced architecture and instruction set as the MU9C2480A/L.
Content-addressable memories, also known as associative memories, operate in the converse way to random access memories (RAM). In a RAM, the input to the device is an address and the output is the data stored at that address. In a CAM, the input is a data sample and the output is a flag to indicate a match and the address of the matching data. As a result, a CAM searches large databases for matching data in a short, constant time period, no matter how many entries are in the database. The ability to search data words up to 64 bits wide allows large address spaces to be searched rapidly and efficiently. A patented architecture links each CAM entry to associated data and makes this data available for use after a successful compare operation.
While the WidePort LANCAMs are optimized for LAN network address filtering, they are also well suited for applications that require high-speed data searching, such as virtual memories and cache management, data compression and encryption,database accelerators, and image processing.
MU9C4485L Maximum Ratings
Supply Voltage "A" Devices .....................-0.5 to 7.0 Volts
"L" Devices.............................................. -0.5 to 4.6 Volts
Voltage on all other pins ...-0.5 to VCC +0.5 Volts (-2 Volts for 10 ns, measured at the 50% point)
Temperature under bias ...........................-55°C to 125°C
Storage Temperature ................................-55°C to 125°C
