uC53281-EVM

embedded voice module

uC53281EVM

The uC53281EVM module is a hardware platform designed to help developers enable high-quality SIP based VoIP products without having to become media, audio and signaling experts. The software package for the module (available with the kit) features a complete VoIP and Management Middleware system and an open source uClinux BSP. The module integrates into end product by using a simple 50 pin connector and includes all necessary subsystems to support full duplex audio, network, I/O and serial connections with minimal external circuitry.

The kit provides all the necessary tools to:

  • Evaluate the capabilities of the hardware and software.
  • Act as a prototype system to develop application implementations.
  • Act as a reference to help implement MCF53281 VoIP processor designs.

In addition, Arcturus offers a complete suite of services including; customization, application development, product development, support and training.
