MIPS), 48K instruction and 32K data RAM

• Three-port 10/100BASE-T Ethernet switch with 64K

buffer memory

• Two 10/100BASE-T Ethernet PHYs

• Three wideband audio ADCs and DACs

• 9x9 keyscan controller

• Ethernet status LED driver

• TDM interface supporting IOM-2®

• 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)

• 1.8/2.5/3.3V Operation

• 1.8W Low Power 0.18u Process Technology

• 256 PBGA Package

HARDWARE PLATFORMS

• BCM91100 Reference Platform

• Complete Ethernet IP Phone reference design in phone

plastics

• BCM91100SV Reference Platform

• Ethernet Residential Gateway reference design

SUMMARY OF BENEFITS

• 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

• Segments network, preventing any restriction on

number of hops

• 100 MHz MIPS32 CPU Supporting:

• H.323, H.248/Megaco and SIP

• Application program

• 140 MHz DSP Supporting:

• G.711, G.726, G.729A/AB/E, G.723.1/A, G.728

• Half- and full-duplex speakerphone operation

• Two- and three-channel conferencing

• Fax relay (T.38, V.17, V.29, V27ter)

• Ancillary telephony algorithms

• 10/100BASE-T Ethernet MACs and PHYs

• Provides Auto MDI/MDIX enabling the use of straight

or crossover cables in either port

• Wideband Audio CODECs

• Enables support of emerging wideband vocoding

standards

• Glueless Interface to BCM4210/4100 HPNA MAC and

AFE Devices

• Enables low-cost home networking IP phone prototyping
