The integrated CPU of the STx5300 is a 300MHz ST231 core, a member of the ST200 series which was designed specifically for video and audio streaming applications such as MPEG-2, MPEG-4 and MP3 in digital consumer applications, where high performance, low silicon implementation costs and low power consumption must be combined with rapid development to ensure minimum time-to- market. The ST200 delivers an EEMBC ConsumerMark(2) of 37.2 while maintaining the low power benefits of a lower clock frequency. Full software development support is provided through evaluation boards and complete STAPI software (ST's Application Programming Interface).

As well as driving advanced end-user applications, the core has power to spare to implement system services in software, thereby reducing costs for STB manufacturers. The STx5300 family provides support for the Linux operating system, an emerging requirement for many operators, in addition to supporting legacy software.

"With an increase of over 500% in on-chip processing power we are providing consumer electronics manufacturers with the capability to support the demanding interactive TV applications of today and tomorrow," said Armando Caltabiano, VP and General Manager of the Retail and Satellite Division of ST's Home Entertainment Group. "At the same time the ability to save hardware by implementing more system functions in software will reduce production costs in this very price-sensitive market."

The new device embeds a USB2 Host interface which allows peripherals to be easily added to a basic STB in order to provide a low cost upgrade path for additional functionality. In particular, it would allow the STB in the field to become a Digital Video Recorder (DVR), by the addition of a hard disk drive.

The STx5300 decoders are available in a low-cost 27x27 PBGA package, with a pin-out that allows a two-layer PCB design. Samples are available now, with volume production scheduled for Q3 2005 and are priced at $11 when purchased in production volumes.
