The chip architecture was designed specifically with low-power and small footprint in mind for wireless handheld applications. The BCM1160 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 1.1, 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 BCM1160 device. The BCM1160, with the BCM4318, offers a highly optimized two-chip solution for WLAN IP Phones. The BCM4318 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, and battery life. WLAN IP Phone Reference Design To accelerate the product development cycle and time to market, the BCM1160 comes complete with a reference design including schematics, layout, BOM and VoIP and 802.11 networking software.
