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. Functions • Support for JPEG format • Real-time decoding of motion-JPEG with rate of 30 frames/sec • Lowest solution cost for amusement, game, PC systems • Support for YUV 4:1:1 color format • YUV or RGB digital video outputs compatible with optional video format • Programmable picture and display window format • Support for trick display: scrolling, overlaying • Standard 8/16-bit microcontroller interface with DMA support for compressed data input • Support SOI and EOI markers • Direct connect to video DAC • Direct connect to 2 M or 4 M DRAM as bit and frame buffers • Two Q-tables included • High-speed processing by fixed Huffman tables Package Dimensions unit: mm 3182-QFP128E [LC82220] SANYO: QIP128E SANYO Electric Co.,Ltd.
