STV3500
DESCRIPTION
This integrated circuit (IC) is dedicated to low-cost
100-Hz TV chassis. Combined with a digital multistandard video decoder (STV2310) delivering an
ITU-R BT.601/656 video stream and a 2H video
scan IC, it provides a cost-effective, high-performance solution for 2H applications. The STV3500
includes a field or line up-converter, a 32-bit ST20
CPU core with all peripherals required for controlling the TV chassis. Teletext data is extracted from
the incoming stream and decoded by the CPU. An
embedded On-Screen Display (OSD) generator
delivers the text and graphics. The Video Display
Pipeline performs feature box image processing
such as picture improvement, horizontal and vertical rescaling and Temporal Noise Reduction.
The chip operates with a single external SDRAM
that is used for the field-rate up-conversion and
text and graphic generations.The external
SDRAM can be configured as a single bank of 16/
64/128 Mb (16-bit configuration) or a dual bank of
16 to 256 Mb (32-bit configuration). Application
program codes are stored in an external Flash
memory and executed from the SDRAM.
The STV3500 is designed using an 0.18 micron
CMOS process and delivered in a 160-pin PQFP
(0.65 mm pitch) package.
The ST3500 completes the Digital IC Core family
(STi5xxx, STi7xxx) which offers common CPU and
software platforms based on STMicroelectronics’
32-bit ST20 CPU core.
