SANYO LC82220 Datasheet

Overview

The LC82220 is a single-chip JPEG decoder designed for
wide range of digital video playback applications
including amusement systems, video games and PC JPEG
playback cards. The LC82220 is capable of decoding
JPEG bitstreams of SIF resolution with a picture rate of 30
frames/sec. The digital video output can be formatted for
NTSC, PAL, SECAM, or any other optional video
standard. The complete decoding function is realised with
the LC82220, a standard 8-bit or 16-bit microcontroller
and a bank of DRAM. A typical memory configuration is
a single 128 k × 16 or 256 k × 16 DRAM. The LC82220
also supports efficient video display functions such as
scroll and overlay.
