GENERAL DESCRIPTION
The LANCAM consists of various depths of 64-bit Content Addressable Memories (CAMs), with a 16-bit wide interface.
DISTINCTIVE CHARACTERISTICS
• High density CMOS Content Addressable Memory (CAM)
• 1K (1480B), 4K (4480B), 8K (8480B) words
• 64-bit per word memory organization
• 16-bit I/O
• Fast 50 ns compare speed
• Dual configuration register set for rapid context switching
• 16-bit CAM/RAM segments with MUSIC’s patented partitioning
• /MA and /MM output flags to 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
• 44- and 64-pin TQFP package
• 3.3 Volt operation
APPLICATION BENEFITS
• New low-cost LANCAM family in a space-saving
TQFP package
• Fast speed allows processing of both DA and SA
within 450 ns, equivalent to 138 ports of 10 Base-T or
13 ports of 100 Base-T Ethernet
• Full CAM features allow all operations to be masked
on a bit-by-bit basis
• Powerful, LANCAM A/L compatible instruction set
for any list processing need
• Shiftable Comparand and Mask registers assist in
proximate matching algorithms
• Cascadable to any practical length with no
performance penalties
• Industrial temperature grades for harsh environments
• Dual footprint connections to conserve board space
• 3.3 Volt for lower power systems
