InstaVoIP 516-CN Module

InstaVoIP® 516-CN Module

A VoIP hardware/software combination

The InstaVoIP 516-CN Module is a standalone hardware module ready to be connected into an existing hardware platform or used as the foundation of a new product. Based on a powerful Analog Devices Blackfin processor, the 516-CN includes an Ethernet connection, 4 MB of Flash, 16MB of SDRAM, and a 48kHz capable stereo audio codec. The 516-CN is based on Unicoi’s industry-leading embedded software including the Fusion RTOS, TCP/IP stack, Voice Engine, SIP stack, and VoIP Call Manager. Out-of-the-box, 516-CN is immediately capable of creating 8-way conference calls using G.729 or other codecs and still has enough free processing power to run user applications. The InstaVoIP 516-CN Module is designed and manufactured in the US.

Start Quick with the DevKit

The InstaVoIP 516-CN Module Development Kit consists of one InstaVoIP 516-CN Module, one debug carrier board, USB cable (for power only), Ethernet cable and headset. The initial InstaVoIP 516-CN Module Development Kit requires the VisualDSP++® Development Environment from Analog Devices along with a JTAG Emulator. The development kit is designed and manufactured in the US.


Production Ready Modules

Once your design using the 516-CN Development Kit is complete and it is time to go to production, 516-CN Modules can be purchased in any quantity.


A low-power, "Green" Module

A typical IP Phone uses 1 to 4 watts of power just sitting on the desk in an idle state. InstaVoIP 516-CN Module uses less than 5 milliwatts in idle mode and 600 microwatts in Deep Sleep mode. This low power design allows InstaVoIP to be the foundation for a wide variety of “GREEN” consumer and business products.
