Applications

The STi5200 has an embedded 266 MHz ST40 CPU for applications and device control.

DDR1 SDRAM memory is used for higher performance, to allow the video decoder the

required memory bandwidth for H.264 decoding and sufficient bandwidth for the CPU and

the rest of the system. A second memory bus is provided for flash memory storing resident

software and for connecting peripherals.

A hard-disk drive (HDD) can be connected as an expansion drive using the USB 2.0 port.

The USB port can also be used to connect to a DOCSIS 2.0 CM gateway for interactive

cable applications.

The STi5200 is supported by STMicroelectronics’ STAPI software.
