GENERAL DESCRIPTION
The SAA7382 decoder is a block decoder buffer manager for high-speed CD-ROM applications that integrates real-time error correction and detection and host interface data transfer functions into a single chip.

FEATURES
• CD-ROM (Mode 1) and CD-I (Mode 2 - Form 1 and Form 2) formats supported
• Real-time error detection and correction in hardware
• Suitable for double speed, n = 2.
• Maximum host transfer burst rate of 8.3 Mbyte/s
• Corrects two errors per symbol with erasure correction
• 36 kbit of on-chip error correction buffer RAM
• 12-byte command FIFO and 12-byte status FIFO
• Compatible with the Advanced Technology Attachment (ATA) register set and the Advanced Technology Attachment Program Interface (ATAPI) command set
• Operates with popular memories. (up to 128 kbyte SRAM; 1 to 16 Mbit DRAM, different speed grades, nibble or byte wide)
• Interface to Integrated Drive Electronics (IDE) bus without external bus drivers
• Q-to-W subcode buffering, de-interleaving and correction are supported
• Device can operate with audio RAMs. A RAM test allows bad segments to be identified.
