Overview

The LC82210 is a JPEG encoder/decoder that handles

motion JPEG. When encoding, the LC82210 accepts an

A/D converter generated digital video input signal and

encodes that signal in real time. When decoding, the

LC82210 decodes a compressed decoded signal and

produces a digital video signal that can be directly input to

a D/A converter.

Features

• Encoding/decoding based on the JPEG standard

• The image size can be set arbitrarily.

• I/O image format Y : U : V = 4 : 2 : 2

• JPEG format Y : U : V = 4 : 2 : 2 or Y : U : V = 4 : 1 : 1

• Process 640

× 480 images 30 frames per second

• Memory control function for the image memory used

for display, capture, and other image functions

• Supports the use of either 1M, 2M, 4M, 4M

× 2 or 16M

bit of DRAM for image memory.

• Supports fixed compression ratio encoding.

• Image memory can be accessed by external systems.

• Image memory compression function

• Supports a function for compressing/expanding part of

an image.

• Supports both x86 and 68xx family CPUs. Also

supports DMA transfers of compressed data.

• Low power mode

• Power-supply voltage: 3.3 V (internal) 5 V (pin) : LC82210

3.3 V (single)

: LC82210L
