PRODUCT
Brief
BCM6352
The BCM6352 is a highly integrated system-on-a-chip solution
for use in security and voice-enabled Ethernet, DSL and PON
(passive optical network) CPE. It combines the power of a high
clock-rate 32-bit MIPS CPU with hardware acceleration for
ATM, HDLC, security processing to spare the CPU for customer -
differentiating, and value-added software applications.
In addition to the hardware ATM, HDLC and security
acceleration, the BCM6352 integrates a two-port 10/100 Mbps
Ethernet switch with support for line-rate WAN-to-LAN routing,
an MII interface to seamlessly connect switch chips, extensive
hardware and software support for VLAN tagging, QoS
functionality to support business class routing applications, and
features like auto-MDIX to minimize Ethernet support issues.
The BCM6352 also provides a USB 1.1-compliant interf ace, two
UART ports and a host of industry standard I/O ports (GPIO).
The USB port functions as a LAN connection for a single
Windows®-based PC. The UARTs can be used for console,
modem or debug ports.
The BCM6352 provides hardware acceleration for multi-line
VoIP and VoDSL applications and includes a voice processor and
four internal SLACs. It can also control external SLACs
connected via the PCM highway, or from external DSPs using
the embedded IOM-2 controller.
The BCM6352 provides a high-speed multi-peripheral
expansion bus to extend connectivity options to 802.11,
BluetoothTM, HPN A, Ethernet, and other networking technologies
from Broadcom and third parties.
The BCM6352 is provided with a complete software stack and
documentation to enable rapid hardware and software
application development. Extensive online support is available to
ensure efficient development of next-generation security and
voice-enabled Ethernet, DSL, and PON CPE solutions.
