SAA7381

` Supports real time error detection and correction in hardware. Error correction to n = 27, error detect to n = 30 and raw data transfer to n = 32.
` DVD-ROM supported in combination with the SAA7335
` Direct generic interface to external Small Computer Systems Interface (SCSI) controller devices
` Operates with up to 16 Mbytes DRAM
  Hyper-page DRAM up to 33 Mbytes words/s burst
  Fast-page DRAM at up to 17.5 Mbytes words/s burst
` Has fixed n = 1 or n = 2 rate (44.1 or 88.2 kHz) I2S-bus multimedia output for simple audio/video output; features for CAV/quasi-CLV support
  Supports Philips multimedia audio CODEC
  Provides 'SHOARMA' Red Book audio buffer
` IEC 958 (SPDIF, AES/EBU and DOBM) output with Q-W subcode and programmable category code, output at n = 1 rate
` Device registers are memory mapped for faster direct access to the chip
` Provides direct access from sub-CPU to buffer RAM to support scratchpad accesses. This eliminates the need for extra RAM chips in the system
` Automatic sequencing of ATAPI packet command protocol, including command termination
` Automated data transfers to and from the host using PIO, DMA and ultra DMA.

The SAA7381 is a block decoder/encoder and buffer manager for high-speed CD-ROM/CD-R functions, that integrates real time error correction and detection and bidirectional ATAPI transfer functions into a single chip.
