ENTERPRISE IP PHONE CHIP
FEATURES
SUMMARY OF BENEFITS
• The BCM1101 is the most highly integrated silicon solution for
feature enhanced Voice over IP enterprise phones
• The BCM1101 Integrates:
• 150 MHz MIPS32 CPU (165 DMIPS) with 8K I-cache and 4K
D-cache
• Superscalar 108 MHz ZSP DSP with dual-MAC (216 MIPS),
48K instruction and 32K data RAM
• Three-port 10/100BASE-T Ethernet switch with 64K buffer
memory
• Two 10/100BASE-T Ethernet PHYs with in-line power over
Ethernet support
• Three wideband audio ADCs and DACs
• 9x9 keyscan controller
• Ethernet status LED driver
• TDM IOM-2® port
• Two UARTs
• Two high-speed serial ports
• General purpose I/O
• Interrupt control unit
• DMA support unit
• SDRAM interface
• External bus interface
• IEEE 1149.1 (JTAG)
• 0.18µ process technology, 1.8/3.3V
• 1.1W peak, 0.3–0.8W standby modes
• 256-pin PBGA package enables 4-layer PCB designs
• 10/100BASE-T Ethernet Switch with 802.1p/Q Support
• 802.1p priority queuing ensures QoS for voice packets and
minimizes latency
• Supports modification of 802.1p priority tags on packets to
enforce priority tagging rules
• 802.1Q VLAN support allows for segmenting physical
networks into multiple logical networks
• 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
• Segments network, preventing any restriction on number of
hops
