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.

The BCM1161, with the BCM4318E, offers a highly optimized

solution for WLAN IP phones. The BCM4318E is a single-chip

802.11b/g baseband, MAC, and radio device. This two-chip solution

enables best-in-class WLAN IP phone design in terms of total

component count, size, range, voice quality, and battery life.

WLAN IP Phone Reference Design

To accelerate the product development cycle and time to market, the

BCM1161 comes complete with a reference design including

schematics, layout, BOM and VoIP and 802.11 networking software.
