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
