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 customerdifferentiating, 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 interface, 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(R)-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, HPNA, 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.
