Description

The Broadcom BCM1115 is designed for use in cost-sensitive, single Ethernet port, Enterprise IP Phone products. It is complimentary to the BCM1101 VoIP CPE engine, which is ideally suited for higher-end 2-port Ethernet VoIP products that require an integrated Ethernet switch and a second Ethernet port.

Key modules integrated in the BCM1115 include a MIPS32 87 MHz processor with 8K 2-way set associative Icache and a 4K 2-way associative D-cache. This MCU supports the VoIP protocol stacks, jitter buffer management, and application program. Programming is done in C, on top of Broadcom's object-oriented signal processing API.
