• Manufacturer Part Number: bcm1160
• Description: Mobile Voip Processor
• Manufacturer: Broadcom Corp.

The BCM1160 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 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.
