A second memory bus is provided for flash memory, storing resident software, and for

connection of peripherals. This bus also has a high speed synchronous mode that can be

used to exchange data between two STi7200 devices.

A 32-bit MPX initiator (EMI module) and target (EMPI module) interconnect external devices

such as the STVi498.

A Blu-ray disc and hard disk drive (HDD) can be connected through the serial ATA interfaces

(2x). An expansion hard disk drive can be connected through a USB 2.0 port (3x). See

Figure 4.

For IP-TV and home network applications, the two integrated 100BT Ethernet controllers

with MII/RMII interface can be used for IP delivery and distribution, as shown in Figure 1.

The USB or Ethernet interfaces can also be used to connect to a DOCSIS 2.0 CM gateway

for interactive cable applications.

The STi7200 is supported by STMicroelectronics’ STAPI software.
