ENTERPRISE IP PHONE CHIP
FEATURES
SUMMARY OF BENEFITS
The BCM1113 is the most highly integrated silicon solution
targeted for midrange Voice-over IP enterprise phones
The BCM1113 integrates:
87.5-MHz MIPS32™ CPU (96 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
9 x 9 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
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
