MLN7010
is a highly integrated and cost-effective
single-chip for 1-port Ethernet
to
HDLC (High-level Data Link Control)
bridge. The Ethernet Interface
supports
10 Mbps and 100 Mbps data rates,
full and half duplex, 802.3x flow
control in full
duplex and backpressure for flow
control in half duplex. It ijqnterfaces
with standard
Ethernet devices using the IEEE
802.3 MII (Media Independent Interface)
and
other common Ethernet interfaces.
HDLC can transform Ethernet frame
to HDLC
frame. MLN7010 supports the HDLC
bit-synchronous interface mode.
No external
memory buffer in applications
is required because MLN7010 has
an embedded
SRAM as a packet storage memory.
The MLN7010 also supports the
various
packet filtering and traffic shaper.
