Preliminary Data Sheet

WidePort LANCAM^®Family

APPLICATION BENEFITS

DISTINCTIVE CHARACTERISTICS

Enhances Ethernet and Token-Ring LAN bridges

and switches:

Ø 4096 (4485A/L), 2048 (2485A/L), and 1024

(1485A/L) word CMOS content-addressable

memories (CAMs)

64-bit width stores 48-bit MAC address plus

associated data (Port ID, time stamp,

“permanent” flag)

Ø 64-bit word width

Ø 32-bit I/O compatible with the MU9C1485

Ø Fast 50 ns compare speed

32-bit I/O supports multiple ports of fast

(100 Mb) Ethernet or Gigabit Ethernet

Station list depth flexibility with choice of

pin-compatible device densities and

glue-free cascading

Ø Dual configuration register set for rapid

context switching

Ø Increased flexibility of MUSIC’s patented

CAM/RAM partitioning

3.3 Volt option for low power systems

Industrial temperature grades for harsh

Ø 80-pin TQFP package with the same pinout as

the MU9C1485 and MU9C1965A/L

Ø 5 volt (A) or 3.3 volt (L) operation

environments
