The BCM1100 is the most highly integrated silicon
solution for Voice over IP Enterprise Phone and
Ethernet Residential Gateway applications.
10/100BASE-T Ethernet Switch with 802.1p Support
• Ensures QoS for voice packets and minimizes latency
• MIPS32 CPU not burdened by data packet processing,
leaving more cycles for application program
• Enables wire-speed non-blocking operation
• Blocks unnecessary traffic by learning local MAC
addresses
•

•
The BCM1100 Integrates:
• 100 MHz MIPS32 CPU (110 DMIPS) with 4K I-cache
and 4K D-cache
• Superscalar 140 MHz ZSP DSP with dual-MAC (280
MIPS), 48K instruction and 32K data RAM
• Three-port 10/100BASE-T Ethernet switch with 64K
buffer memory
• Segments network, preventing any restriction on
number of hops
• Two 10/100BASE-T Ethernet PHYs
• Three wideband audio ADCs and DACs
• 9x9 keyscan controller
