A state-of-the-art embedded microprocessor from STMicroelectronics has been selected for a next-generation IP telephone from snom technology, a leading producer of VoIP equipment for enterprise communication.
ST’s SPEAr 300 microprocessor combines an advanced ARM processor core with a rich set of audio, communication and connectivity interfaces to form the heart of the newest snom 870 VoIP telephone. The Linux-based phone comes with an intuitive user interface and a high-definition touch-screen colour display, wideband audio, an integrated XML browser, and a wide range of additional features.
The SPEAr microprocessor runs the operating system and Graphical User Interface of the snom 870 phone and handles all the computing-intensive tasks, including Ethernet communication, real-time voice coding/decoding, telephone conferencing, and echo compensation. ST’s microprocessor enhances the phone’s connectivity and extensibility with Ethernet MAC, three USB 2.0 ports, an analog-to-digital converter, and WLAN through USB.
A companion chip to SPEAr 300 is ST’s STM8 8-bit microcontroller, which manages the snom 870’s touch screen display, as well as the keyboard and the receiver.
