The Broadcom BCM6345 combines an ADSL transceiver and analog front end (AFE) with a MIPS32 CPU, a 10/100 Ethernet interface, a USB 1.1 transceiver, a PCMCIA interface, and a generic expansion bus into a single chip.
The embedded MIPS32 CPU, with Broadcom-supplied software, controls the ADSL modem, performs high-performance bridging and routing between the ADSL WAN interface and various LAN interfaces, and allows for customer application development.
