SANYO LC82220

Ordering number : EN*5422
CMOS LSI
LC82220
Motion JPEG Decoder LSI
Preliminaly
Overview
Package Dimensions
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.

System Configuration Example
1. Separate code bus type
This is a system in which the code and system busses are separated. The coded data input does not load down the
system bus.
No. 5422-5/6
LC82220
2. Shared code bus type
This is a system in which code bus and the system bus are connected. Coded data is written by the CPU, or
alternatively, data can be written using the DMA controller.
