STi5162
1.1
General
The STi5162 is the latest in the family of STBus set-top box ICs providing high-performance,
low-cost system-on-chip (SoC) for MPEG processing in digital terrestrial STBs. It is derived
from the STi5107, with the addition of a DVB-T COFDM demodulator and supports multiple
platforms using a unified architecture.
The STi5162 delivers enhanced performance with respect to previous devices. Main
memory is based upon a single 16-bit external SDR SDRAM or DDR DRAM.
The display architecture of the devices is based upon a high performance blitter engine that
supports CLUT8 and RGB16 formats for background, video and OSD/graphics displays. It
makes the porting of middleware easier with improved rendering.

The STi5162 is designed for low-cost basic STB applications.
Its BGA package allows the use of a simple 2-layer PCB, with all signals and power supplies
being routed through the top PCB layer. This leaves the bottom PCB layer dedicated to the
ground plane and JTAG connections.
The STi5162 provides the following features:
● SDR and DDR SDRAM memory interface
● Digital video output port (exclusive with parallel Flash)
● serial Flash interface for program storage
● serial TS input port
● two ASCs (UARTs)
