Data Sheet Draft
MU9C1480A/L LANCAMs^®
APPLICATION BENEFITS
The 1024 x 64-bit LANCAM facilitates numerous
operations:
Ø New package saves space
Ø New speed grade allows processing of both
DA and SA within 560 ns, equivalent to 111,
10 Base-T or 11, 100 Base-T Ethernet ports
Ø Full CAM features allow all operations to
be masked on a bit-by-bit basis
Ø Expanded powerful instruction set for any
list processing needs
Ø Shiftable Comparand and mask registers
assist in proximate matching algorithms
Ø Fully compatible with all MUSIC LANCAM
series, cascadable to any practical length
without performance penalties
