The CXD1804AR is a CD-ROM decoder LSI with a
144 pin LQFP (Plastic)
built-in Fast SCSI controller.
Features
• Fast SCSI controller (Target mode)
• Maximum transfer speed of 10MB/s (when using
Fast SCSI synchronous transfer)
• SCSI overhead reduced by executing multiple
SCSI sequences
• Supports SCAM Level 2
• Compatible with CD-ROM, CD-I and CD-ROM XA
formats
• Real-time error correction
• Capable of handling up to twelvefold-speed playback
• Multiblock auto-transfer function
• Can read subcode-Q data for each byte from the
sub CPU
• Real-time subcode (R to W) error correction
• Serial transfer of commands to CD DSP
• Connectable with standard DRAM of up to 8M bits
(1024K bytes)
• DRAM bit width selectable for 8 bits or 16 bits
