Preliminary
CMOS LSI
LC895125Q, 895125W
CD-ROM Driver with On-Chip SCSI Interface and
Subcode Functions
Functions
CD-ROM ECC function, subcode read function, SCSI
interface
Features
• On-chip SCSI interface (with built-in SCAM selection
register)
• Supports 8× playback - Using ×16 80-ns DRAMs
• Supports 4× playback - Using ×16 80-ns DRAMs or ×8
70-ns DRAMs
• Transfer rates: 10 MB/s (synchronous), 5 MB/s
(asynchronous) using ×16 80-ns DRAMs^*1
• Transfer rates: 8.467 MB/s (synchronous), 4.2336 MB/s
(asynchronous) using ×8 70-ns DRAMs^*2
• Supports the connection of up to 32 Mb of buffer RAM
(using DRAM)
• The user can freely set the CD main channel, C2 flag,
and other areas in buffer RAM.
• Batch transfer function (transfers the CD main channel
and C2 flag data in a single operation)
• Multi-block transfer function (automatically transfers
multiple blocks in a single operation)
• High-speed transfer mode supports a 10-MB/s
(synchronous) transfer rate using ×8 80-ns DRAMs
• Subcode ECC function
Note: 1. For speeds up to 8× speed, use a SCSI master
clock frequency of 20 MHz.
Note: 2. For speeds up to 4× speed, use a SCSI master
clock frequency of 16.9344 MHz.
