GENERAL DESCRIPTION
The MU9C8328 speeds up bridging operations using Ethernet controller chips with serial NRZ data outputs, such as AMD’s MACE™, National’s SONIC™, and Motorola’s QUICC™ controllers, by parsing the Ethernet frame independently of the Ethernet controller device, and notifying it whether to accept or reject the incoming frame.

APPLICATION BENEFITS
➢ Single port 10 MHz Ethernet address parsing,
   filtering, and learning state machine at wire
   speed
➢ Glue-free interface between the MUSIC
   LANCAM® Family and AMD, National,
   Motorola, or similar Ethernet Controllers
   having an NRZ serial data port
➢ Selectable filtering and learning decisions
   on DA and SA compares
➢ Supports cascaded MUSIC LANCAM series
   for long station lists
➢ Host processor port for LANCAM
   initialization and housekeeping activities
➢ Supports system clock rates from 20 MHz to
   33 MHz
➢ 100-pin PQFP package
➢ 5 Volt operation
