The BCM1161 VoIP processor offers a high level of system
integration, performance, and features for wireless IP phone handsets.
The chip architecture was designed specifically with low-power and
small footprint in mind for wireless handheld applications.
The BCM1161 is a highly integrated mobile VoIP processor based on
an ARM9 CPU architecture and integrated analog voice band codec.
The device integrates all phone peripherals such as keyscan and USB
2.0, as well as an external memory interface supporting NOR or NAND
Flash and SRAM or SDRAM. Also included are interface functions
and drivers to enable auxiliary components, such as microphone and
speaker, to connect directly to the BCM1161 device.
