GENERAL DESCRIPTION
The MU9C1965A and MU9C1965L LANCAM MPs are 1024 x 128-bit content-addressable memories (CAMs), featuring a 32-bit wide interface. The wide comparand width allows the LANCAM MP to handle multiple protocols in a single search table device.

DISTINCTIVE CHARACTERISTICS
➤ 1024 x 128-bit CMOS content-addressable memory (CAM)
➤ 32-bit I/O
➤ Fast 50 ns compare speed
➤ Dual configuration register set for rapid context switching
➤ 32-bit CAM/RAM segments with MUSIC’s patented partitioning
➤ /MA and /MM output flags enable faster system performance
➤ Readable Device ID
➤ Selectable faster operating mode with no wait states after a no-match
➤ Validity bit setting accessible from the Status register
➤ Single cycle reset for Segment Control register
➤ 80-pin TQFP package
➤ 5 volt (1965A) or 3.3 volt (1965L) operation

APPLICATION BENEFITS
The 128 bit x 1024 LANCAM MP facilitates numerous operations:
➤ Simplified switching/routing address filtering and translation
➤ Improved VLAN mapping:
   ➤ DA, SA, Port ID to VLAN ID
   ➤ Filter on any field
➤ IP to MAC, MAC to IP filters and translation
➤ DA, SA to ATM VC
➤ Shiftable comparand and Mask Register 2 assists proximate matching algorithms
