STMicroelectronics' SPEAr 300 embedded microprocessor forms the heart of the newest snom 870 VoIP telephone from snom technology, one of the leading manufacturers of VoIP equipment for enterprise communication. The Linux-based phone, which boasts an intuitive user interface with a high-definition touch-screen color display, wideband audio, an integrated XML browser, and plenty of additional features, arrived on the market in September 2009.
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.
