General Description
non
head-of-line
TC9205M is a fully integrated 5 Port 10/100/1000
smart Ethernet switch controller designed for low
cost and high performance solutions. The chip
embeds necessary SSRAM for packet buffering
and MAC address table. It provides MII / GMII /
interface for all ports.
A store-and-forward switching method using a
non-blocking architecture is implemented within
TC9205M to improve the availability and
bandwidth. The chip embeds packet buffer, which
it supports normal and priority queues for each
transmission port.
TC9205M provides evolved CoS with four levels
of priority. The priority can be checked via layer 2
(802.1Q VLAN Tagging) and/or layer 3 (IP Header
TOS bits) packets. Port based priority is also
provided to ensure transmission with precedence
for all packets incoming from selected port(s).
This feature allows improved support for
multimedia applications.
The chip embeds IEEE 802.3 MAC functions for
each port and these functions support full and half
duplex modes for both 10 and 100 Mbits/s data
rates and full duplex for 1000 Mbit/s. Each port
includes dedicated receive and transmit FIFOs
with necessary logic to implement flow control for
both full and half duplex modes. TC9205M uses
IEEE 802.3x frame based flow control for full
duplex and backpressure for half duplex.
TC9205M handles an 8K address-lookup table
with searching, self-learning, and automatic aging,
at very high speed and excellent address space
coverage. Forwarding rules are implemented
according to IEEE 802.1D specifications. Filtering
capabilities for bad packets and packets with
Reserved Group Address DA are also provided.
The pin configuration interface comprises 40
configurations, which are shared with GMII output
pins by latching the configuration data during
reset. An external EEPROM device can also be
used to configure the TC9205M at power-up. With
reference to pin configuration interface, the
EEPROM extends the chip’s configuration
capability with new features and enables a
jumper-less configuration mode using a parallel
interface for reprogramming. A virtual internal
EEPROM mode is also provided to enable the
use of the programming interface in the absence
of external EEPROM. TC9205M can make
effective use by most of its features using only the
pin configuration interface.
TC9205M includes a physical layer configuration /
polling entity, which it is use to configure the phy
functions and to monitor the physical layer
transceiver’s speed, duplex mode, link status and
full duplex flow control ability for each port. The
chip provides four modes for phy configurations,
which these modes include auto-negotiation
disable procedure for 10/100 speed modes. The
phy configuration information is stored in
EEPROM setting.
The chip requires a 25 MHz system clock, dual 2V
and 3.3V power supply and is packaged in PBGA
292.
